At present, the international trade in the lithium iron phosphate leading enterprises are mainly three, namely the A123 U.S. companies and prestige to the company and Canada’s Phostech company. They have mastered the core patented technology related fields.

China’s DVD industry to avoid the tragedy of patents, a patent defense of lithium iron phosphate has already started.

June 10, Professor Zhang Chu, China University of Politics and Intellectual Property Research Centre, Canada Phostech an individual held by the “lithium iron phosphate battery” patent to the State Patent Review Committee (hereinafter referred to as the “Patent Reexamination Board” ) for valid applications received have been received notification.

For domestic companies, if unable to break the patent difficulties lithium, lithium battery industry or to repeat the DVD industry patents by foreign monopolies in the past. More importantly, not only to the lithium iron phosphate industry in China’s future development, the future may be related to the fate of my electric car industry.

Lithium battery patent barriers difficult to break

This breakthrough in lithium battery patent fight the plight of the industry has been started.

June 12, Intellectual Property Research Center of China University of Political Science by the China Battery Industry Association (hereinafter referred to as “Battery Industry Association”) commissioned, but also to the Patent Reexamination Board Phostech company held the patent invalid request made.

“In early July, and the Battery Industry Association, I received a patent review were accepted members informed, the next step is to wait for the oral hearing of the.” Zhang Chu told the “China Business” reporter, the Patent Reexamination of the oral hearing, the equivalent of court cases during the trial. The two sides should be present in court, their views and exchange of evidence presented.

Zhang Chu introduced, this request was mainly based on invalid “Patent Law” article 22 of the novelty and creativity on the provisions of Article 26 claims on the patent specification and the requirements of the and 33 on the scope of patent claims amended provisions. “Currently, we have found several applications for the open literature prior to the date of this patent to deny the novelty and creativity.” Zhang Chu said.

According to experts, and materials in the field of lithium iron phosphate has two core technology patents. One of which is carbon-layering technology patents, the other is carbon thermal reduction technology patents. The former by the Canadian Phostech company has the exclusive right to use and has patents in China. The latter’s patent by the U.S. Gateway to company, has yet to apply for a patent in China.

Changshu, Jiangsu Province, according to Tang’s green energy by the Changsha Institute of Technology Yong Kang Jieshao, lithium iron phosphate is now considered the best power battery, which has a discharge capacity, low cost, non-toxic pollution, security, performance, sources of raw materials widely , and long lifetime. “There used power tools such as electric bicycles, electric drills and digital products, lithium iron phosphate product technology has matured, but, due to immature technology, the lithium iron phosphate for high-power output of small cars.” Sha Yongkang said.

It is understood that, due to the advantages of lithium iron phosphate has been used in electric vehicles. Currently, the world’s major car companies will develop new energy technologies as the future direction of the electric car to become the focus of all areas of contention.

“As the lithium iron phosphate material in the field and the core patented technology, is the foreign company control, the next event of patent disputes, lithium iron phosphate, the patent will be the scene of repeated DVD business, Chinese companies can pre-commitment and effort is foreign companies to make wedding gown. “Zhang Chu warned.

Sword of Damocles hanging overhead, Chinese enterprises

Lithium iron phosphate battery industry, the golden age of electric vehicles along with the development of the industrialization of the arrival.

Industry experts have estimated that by 2012, China will create 500 000 new energy automobile production capacity, such as the use 20,000 yuan bicycle battery measured the average level of prices, the domestic automotive battery market could reach 10 billion yuan. By 2020, new energy vehicles driven global automotive battery market demand will be more than 200 billion yuan.

Such a huge market potential, makes the domestic investment boom iron phosphate lithium battery industry is emerging. Since 2001, Chinese companies are using lithium iron phosphate material development into the area, as of 2009, there were 50 to 60 vendors will soon or have already completed the purchase of production lines.

“In addition to promising market prospects, China’s abundant resources are raised lithium iron phosphate lithium battery industry, the investment boom, one of the reasons.” Sha Yong Kang said.

According to the U.S. Geological Survey report, China’s lithium reserves are about 1.1 million tons, accounting for the world’s 1 / 10. And Guotai Junan Securities report issued this number will refresh to 5.23 million tons. “Our country phosphate, lithium-rich mineral resources, high quality, low price. This iron phosphate lithium battery industry in China’s development provides a good foundation.” Sha Yong Kang said.

Lithium iron phosphate as involved in the field late in the overseas Chinese in the lithium iron phosphate’s technology is also relatively late start. Since 2003, China started on lithium iron phosphate’s patent application, but the first thing foreign patent applications, lithium iron phosphate started in 1997.

Zhang Chu told reporters, lithium iron phosphate’s core patent has been master of several foreign companies, domestic enterprises in this area are concentrated in the peripheral areas of the patent. “Foreign patent hanging overhead like a sword, they might fall on the heads of Chinese companies on our lithium iron phosphate industry pose a huge potential threat.” Zhang Chu said.

Sha Yong Kang believes that foreign companies to take the usual “rovide water for fish” approach. Now, the new energy vehicle technology is not yet ripe, nor the formation of lithium iron phosphate mature business model. Once the formation of new energy vehicles mature technology, new energy vehicles in China form a high volume of exports, the domestic lithium iron phosphate into the period of rapid development, master the core patented technology of foreign companies are likely to form a patent pool to deal with the Chinese iron phosphate Li-ion battery business.

Domestic enterprises is the scourge of the guard

The advent of lithium iron phosphate has not been long in the technology, from its birth, the patent would not stop fighting.

First by academics known as the “Father of lithium iron phosphate,” University of Texas professor of American and Japanese NTT John.Goodenough patent battle between the latter company in Taiwan, “Huaqianxiaozai” buy lithium iron phosphate battery patent is licensed, the same as between Europe and the United States, lithium iron phosphate blows patented technology. December 9, 2009, the European Patent Office ruling to revoke the right granted to the University of Texas lithium iron phosphate of the European patent ownership.

“This decision protects the interests of many European companies, if the revocation of the patent, European businesses will be possible to free development and use of iron phosphate lithium battery technology.” Zhang Chu said, they now want China to follow the example of the European Patent Office’s decision to protect domestic industries.

Relative experts worry, the domestic lithium battery companies who are relatively optimistic about this issue.

Zhejiang, a lithium battery manufacturer that now restrict iron phosphate lithium battery development bottleneck, not the patent issue, but technology is not yet mature, and how to achieve industrialization. “Although there are many interested customers lithium iron phosphate, but few people ordering large quantities directly, but only a few groups to do the battery test. Lithium iron phosphate battery technology is not mature, the performance is not stable, large Most customers only hold a wait and see attitude. “The manufacturer said.

Xiangcai Securities analysts believe the domestic enterprises eager to take the lithium iron phosphate line, but the accumulation of patents and technology still lag behind the United States, Japan, and Taiwan. Current production can reach Le claimed more than 20,000 tons, but subject to technologies and processes, product quality is not a Youshi cause actual yields are low, being able to meet the dynamic needs of Gaoduan iron lithium still imported from Guowaihuozhe China and Taiwan.

University of Texas patent on lithium iron phosphate, in the United States, Japan, Germany, Italy, Britain, France, and Canada has applied for patent protection. Although the patent was revoked in Europe, but the use of the patented product, if exported to the United States and other countries, the risk still exists.

Sha Yong Kang proposed to fundamentally solve the problem, can the following two aspects: First out of the current electric, hybrid, fuel cell group, further developing the technical route, from the technical concepts and principles of the new kitchen. Thoroughly integrated inventory or survey of existing domestic power and the development of lithium battery patents, proprietary technology, further development of lithium batteries.

“Lithium iron phosphate international patent lack of an answer is not solved, we will be in the industrial chain is still in low-end passive position.” Sha Yong Kang said.

Lithium iron phosphate material patent dispute

In 1997, by academics known as the “Father of lithium iron phosphate,” University of Texas professor John.Goodenough on lithium iron phosphate technology-related patent application.

In 1999, John.Goodenough patent application is approved. Because of the patented invention for the post John.Goodenough behavior, ownership of the patent belonging to University of Texas.

Japanese telecommunications company (NTT) has proposed, in 1996, they had already reported the olivine structure of lithium-ion cathode material, patents should belong to them.

In order to compete for ownership of the patent in 2001, the University of Texas and its business license of Quebec water company sued NTT to illegally steal technology secrets. Ultimately, the case settled out of court closed to. U.S. University of Texas admitted “NTT is not stealing its technology secrets”, but NTT was forced to the lithium iron phosphate materials have patents licensed to the University of Texas. In addition, NTT has to pay 30 million U.S. dollars of the settlement.

Japanese companies in the patent war victory, the Quebec Hydro, Phostech company, in turn targeting Taiwan. Taiwan has thousands of large and small, battery manufacturers, many companies did not receive patents. In order to avoid potential patent disputes, some Taiwan companies have chosen the “Huaqianxiaozai” to handle the matter. Taiwan’s powerful energy companies through the purchase of lithium iron phosphate way to get a patent is licensed.

China’s DVD patent loss of business

Occurred in the last turn of the century’s DVD patent fee dispute, the transnational corporations with “the exercise of intellectual property” in the name of China’s DVD business to charge royalties 3 billion yuan and is expected to levy royalties 20 billion yuan; China DVD business, because there is no defensive measures, only to pay large fees.

June 1999, when the DVD began to pop in the market era, 6C (including Hitachi, Panasonic, JVC, Mitsubishi, Toshiba, Time Warner) announced that “DVD Patent Joint License” statement calling on all of the world production of DVD manufacturers must to them to buy “patent license.”

April 19, 2002, China Audio Industry Association in two years time, after many negotiations, finally signed an agreement with the 6C to provide Chinese manufacturers export a platform for every DVD player to its four U.S. dollars to pay royalties. Subsequently, the Association and the 3C (Philips, Sony, Pioneer) have entered into an export platform for every DVD player to pay 5 dollars to its royalties agreement.

With DVD sales of the international market price continued to fall, when the U.S. market retail price of DVD machines only 30 to 40 dollars, Chinese companies export a DVD for each machine would pay about 12 U.S. dollars respectively royalties. Domestic DVD player almost unprofitable export business, many companies no longer produce DVD products or close down.

Society of Automotive Engineers (SAE International) car batteries 1-3 Forum will be held in September at the Shanghai Marriott Hotel Hongqiao. There will be more than 20 world-renowned power from the battery and related industry experts gave a speech. From the global automotive industry, battery industry, the power storage of lithium mining industry and senior engineers, experts and scholars and corporate leaders will gather on the power cell technology to study and exchange.

New energy vehicles and car batteries

In recent years, energy saving slogans all over the world, all walks of life all have engaged in the cause of energy conservation. Now, the Chinese government’s support for energy conservation efforts are increasing year by year, including the development of new energy vehicles for providing great impetus. Recently, the Ministry of Finance, Ministry of Science, Industry and Information Ministry and the Development and Reform Commission jointly issued a “buy on the launch of new energy vehicles to subsidize a private pilot’s Notice”, these initiatives not only promote the development of new energy vehicles, but also brought along with it closely related to the rapid development of automotive battery market.

New energy vehicles are currently the main plug-in vehicles and pure electric vehicles and so on, its development depends largely on battery technology. And with lithium battery as the chief representative of the cost, performance, life and charging, and security are still many problems, this is the bottleneck of the development of new energy vehicles, hard to spread.

How will the automotive industry and the battery industry more closely together?

Car battery in the battery industry’s top technology development, and because is directly related to the popularization of new energy vehicles, so their development for the future development of the automotive industry is of great significance. The development of the battery can power the two industries more closely linked together. In fact, a certain scale in China has thousands of battery companies engaged in production of automotive battery several hundred, while the real ability to set foot in automobile production enterprises battery only a few dozens. Car batteries each year and there are many exhibitions and seminars, unfortunately only with their industry focus, unable to meet the mutual understanding and communication of urgent need.

This year’s American Society of Automotive Engineers (SAE International) car batteries Forum invited the United States Advanced Automotive Battery (Advanced Automotive Batteries) president and the whole battery consulting company (Total Battery Consulting, Inc.) Founder, Dr. Anderman did the President. Dr. Anderman is the world’s leading battery experts, enjoy a high reputation in the industry.

With Nissan North America, announced the upcoming Nissan Leaf of the battery pack will be 8 years or 100,000 miles (161,000 km) warranty. North America Adds a scenic landscape electric vehicles.

Nissan introduced measures this warranty and is expected to fall this year, GM introduced the Chevrolet Volt extended-range electric compact car warranty match.

Leaf fully electric five mini-car, is scheduled to arrive in December a number of specific market dealer. Leaf’s priced at 32,780 dollars. However, commitment by the federal government to buy electric cars for consumers 7500 U.S. dollars of tax credits, making the price of the equivalent of leaf reduced to 25,280 dollars.

The next electric car sold in the U.S. will be the Mitsubishi i-MiEV. Mitsubishi spokesman Daniel arap Moi - Durand said it will debut in autumn 2011, the current manufacturers do not like the maintenance period of the discussion.

Smart models similar situation, in October test vehicles will reach the United States, but two Fortwo electric cars will have to wait until at least 2012, on sale in the United States.

Dollar price of 101 500 Tesla Roadster sports car, the only in the sales of electric cars, bumper to provide 3 years or 36,000 miles (58,000 km) warranty. However, the premise is, however, the time of purchase to pay 12,000 U.S. dollars, buyers can have 8 years to replace the battery after the permissions.

By the financial crisis, foreign dependence on the larger information industry last year by a huge impact. But before half-baked city’s information industry report showed the first half of this year, Jiaxing information industry revitalized.

January to June, extended a rebound of electronic information industry, economic doubled, accelerating revenue growth in the software industry in general took up recovery of channel. Growth rate of the index are much faster than the city average level of industrial enterprises above designated size.

75.55% recovery of electronic information industry

January to June, the city’s electronic information industry (387) completed a total industrial output value of 20.526 billion yuan, up 75.55 percent over last year; complete industrial sales output value of 19.824 billion yuan, up 81.62 percent; an export value of 8.369 billion yuan , an increase of 50.38%; complete main business income of 19.758 billion yuan, up 80.99%; total profit of 1.62 billion yuan. Completed a total of 445 million software revenue, an increase of 67.30%.

Rapid expansion of industrial scale is the development of the first half of the city’s information industry is a major characteristic. January to June, the city scale electronic information manufacturing output grew 75.55 percent, representing the city’s total industrial output value of 9.55%, to become the city’s industrial development, an important pillar industries.

In 28 manufacturing industries, over 2 billion yuan of industrial output value have information of chemical manufacturing, battery manufacturing, micro-motors and other electrical manufacturing, wire and cable manufacturing, electronic components and component manufacturing industries 5. Among them, the information manufacturing chemicals largest industrial output value of over 3.6 billion yuan; battery manufacturing industry grew fastest, up 259.73% This is mainly due to solar cell materials and components products are produced to expand international market rebound .

19758000000 industrial restructuring initial results

Municipal Development and Reform Commission that the relevant person in charge, the information industry during the first half of this year increased more economic data is due to a low base last year. Therefore, the current overall economic growth should be considered to restore growth. In addition, the first half of the city’s information industry’s growth rate high, but in June the growth rate has slowed compared to May, taking into account the base of the second half of last year, is the gradual recovery in the second half of the information industry growth than on slow half the year is expected industrial output value of the information industry is about to complete the 40 billion yuan.

Current industrial restructuring has achieved initial success, economic efficiency improved significantly. January to June, more than the scale of electronic information industry realized main business income of 19.758 billion yuan year on year growth of 80.99%. Main business profit margin reached 8.20%, higher than the same period in 2008, 3.6 percentage points.

At present, some enterprises orders also good, but cost pressures increased, labor, material costs, high export ratio, foreign exchange influenced by the price, because products for export to foreign currency, falling or if the foreign exchange revaluation and eventually obtained RMB revenues less. Depreciation of the euro this year to the European market-based enterprises to greater losses. Part of the business in July, August orders have been significantly better in the second quarter, in September the market situation is not clear.

Municipal Development and Reform Commission that the relevant person in charge, the information industry high outward, with the international market is closely related to the international financial crisis repercussions, many uncertainties still exist, market volatility that may arise at any time. Therefore, any one factor than-expected changes are likely to adversely affect the development of information industry.

Any console gamer will tell you wireless controllers rock — but it’s not unusual to go through a bunch of batteries each year. Chances are, you use rechargeable batteries, which are easier on the wallet (over time) and the environment.
A new rechargeable battery is on the market –USBCell from Moixa — that promises to make it even easier to charge up when not in use.

As the name suggests, these AA batteries recharge through a built-in USB connection, cleverly located under the hinged cap.

Therefore, you can use it like a regular battery in your game controller (or other gadgets and toys, of course) and then charge them up anywhere you’ve got a USB port, such as a laptop. No cables or charging docks are required.

While we haven’t tried out the USBCell yet ourselves, these rechargeable batteries ($17.99 for a 2-pack) are said to charge to 90 percent in 5 hours, while just 1 hour of charging yields about 50 percent of power. A small LED light shows when the battery is charging, and different colors for when it’s at 90 percent and fully charged.

These NiMH (Nickel Metal Hydride) batteries can be reused “hundreds of times” before they need to be replaced, says Moixa.

Concept is gaining in popularity as a low-carbon, the battery can lead to a growing concern.

Used batteries and more pollution

Used batteries a potential pollution has aroused extensive attention. China is the world’s number one battery production and consumption of power, has information that China currently has more than 1,400 battery manufacturers, battery production capacity in 1980 over the United States and ranks first in the world. China’s battery production in 1998 reached 14 billion, while the world total production of dry batteries is about 30 billion.

Such a large number of batteries, making a great problem is exposed, that is, how much pollution the batteries do not destroy our environment. If the one on the 1st cell in the ground rotting, it’s toxic substances can make one square meter of land lost value; throw a coin cell battery into the water, it contains toxic substances which cause pollution of 600,000 liters of water body , water equivalent to a person’s life; used batteries contain cadmium, lead, mercury, nickel, zinc, manganese, which cadmium, lead, mercury is more harmful substances the human body.

Therefore, the collection and disposal of used batteries is very important, if disposed of improperly, may be on the ecological environment and serious harm to human health. While advanced technology has given us the right direction, but my battery is still not optimistic pollution phenomenon. Currently most of our garbage is mixed with used batteries be buried underground, over time, after conversion to battery decay, leaching of heavy metals, both can contaminate groundwater, they may contaminate the soil, eventually, by various means into the human food chain. Biological uptake of heavy metals from the environment through food chain biomagnification, step by step in the higher organisms, thousands of times more enriched, and then enter the human body through the food chain, and in some organs of savings cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.

Thin film solar cells Cheng Xinchong

When the domestic war battle it polysilicon when the feast of thin film solar cells already quietly open seats. Photovoltaic power generation field, as the two main “master”, crystalline silicon cells and thin film batteries, seems to pull a Competition.

As the name suggests is the layer of thin film battery into the solar cell thin films, the silicon is extremely rare and easier to reduce costs, while it is both an efficient energy products, but also a new type of building material, more easily with the perfect combination of architecture. Silicon raw materials in the international market against the background of continued tension, thin film solar cells has become the international PV market development trends and hot spots.

Although thin film solar cells have already emerged, but conversion efficiency is low, attenuation ratio were higher, a few years ago did not attract enough attention from the industry, market share is low. With its technological advances in photoelectric conversion efficiency is rapidly increasing, now more than two years ago increased to about 30% -40%, although still in comparison with crystalline silicon cells have very different, but the use of less materials, simple process low energy consumption, costs are certain advantages, more and more accepted by the industry.

Corresponding to this, following the hot solar modules, polysilicon fever, film photovoltaic cell has become the new investment hot spot areas.

Compared with crystalline silicon cells, thin film cells is much greater potential for cost reduction, driven by rapid technological progress in thin film batteries. Thin-film solar capacity may be the next to reach 20% of the entire solar energy industry, while only 7.6% in 2007, shows that among the space.

Yesterday morning, the City Urban Management Committee and the Municipal Environmental Protection Bureau in Guangzhou City sanitation sprinkler teams handled the transfer of waste batteries work, where the storage of 12 tons of used batteries from Guangdong Province, treatment and disposal of hazardous waste franchise organizations - Huizhou Dongjiang Veolia Ya Environmental Services Ltd., for sound processing.

It is understood that the environmental protection department entrusted by the city, Guangzhou City sanitation sprinkler team since 2003, began more than three-star city hotel, primary and secondary schools, some universities, kindergartens and other units of the obligation to collect waste batteries. Guangzhou this year, a comprehensive classification of the work undertaken to promote garbage collection since the used batteries and other harmful waste are temporary here. According to city environmental protection departments, the current collection of used batteries to store 12 tons will be transferred to Huizhou Dongjiang Veolia Environmental Services Limited, harmless treatment.

2010, global solar PV market size will exceed 12,000 megawatts (MW), and the size of the market in 2009 compared to earlier, the growth rate of more than 60%. The first half of 2010, shipments of solar cells in Taiwan about 816.6MW, annual growth rate of 160.1 percent. Estimate the PV module capacity of silicon the size expected to reach 1,778 MW, annual growth rate of 101.6%.

Global solar PV market in 2010 will show rising trend overall, due in the first half cut rates by the German government’s policy announcement effect, sparking an get the building trend, while in the second half is expected in Italy, France, the Czech Republic and the United States and other countries have plunged into the market, along with Japan, China needs to upgrade, in 2010 the global photovoltaic market is expected to grow substantially.

Industrial Information Institute for Information Industry (MIC) of high Hongxiang industry consultant, said the PV manufacturers in early 2010 to conduct large-scale expansion, in addition to first time silicon material manufacturers have started trial production, the wafers, cells, modules are showing capacity to expand significantly over the situation. Among them, the first and second quarter shipments of silicon solar cell, respectively, rose 307%, 160%, in 2010 shipments are expected to challenge the world’s third-largest or second chance. In most production layout of the Taiwan situation, utilizes the existing petrochemical, semiconductor industry technology strengths, the nearest Gongyingjiage, quantity and stability of the upstream material, the silicon material, silicon Changshangchuangzao the basic living conditions, Suizhedianchi film makers substantial expansion of plants, the growth of upstream industries can be said beyond doubt.

MIC MIC said the financial turmoil has resulted in a substantial decline in unit prices, cost competitive pressures, the European module, solar cell makers for the cost too high to allow outsourcing, eastward under enormous pressure and battery chip manufacturers in Taiwan to quality, prices are relatively competitive advantage, preparing for further significant expansion of production capacity. Observed first quarter of 2009 1,952 MW capacity and the fourth quarter of 2,487 MW capacity growth trend, and the first quarter of 2010 and second quarter were higher than in 2009 over the same period grew 34.9%, 50.5%, production scale rapidly increased to 2,634 MW and 3,104 MW expected second half 2010 to first quarter of 2011, on a quarterly basis will be maintained above 70% capacity growth.

Outlook 2010, in large ICT companies with strong financial, global logistics system, brand, cut into the PV module manufacturing capacity and systems, the photovoltaic industry of Taiwan is concerned, in the past been regarded as the weakest link, then competitiveness can be described as substantial increase in expected future there will be considerable opportunity for a showdown in mainland China manufacturers. The cost and quality advantages, the expected 2010 Taiwan wafers, cells obtained orders for manufacturers should be no doubt. Consequently, the success in obtaining equipment and funding the peak season will be the decision makers a key factor in winning or otherwise.

With the solar cell manufacturers continue to improve the competitiveness, ability to spread this competitive advantage first, downstream, and the virtuous circle shape overall competitiveness, industrial policy remains to be blessing. In addition to new and emerging technologies, manufacturing equipment, system components such as R & D to promotion, capacity-building will help system vendors domestic market and the current pay falls remain certified, financing, evaluation system, are urgent administrative units of the active .

Hydrogen and oxygen fuel cell is a chemical reaction directly through the electrode into electrical energy. The most important feature of this device is due to reaction does not involve combustion, so the energy conversion efficiency from “Carnot cycle”, which limits the energy conversion rate of 60% to 80%. It also has a fuel diversification, clean, low noise and pollution to environment, good reliability and maintenance advantages. Battery requires continuous supply of live material (from the reaction of the substance) - the fuel and oxidizer, which in turn, and quite different from other ordinary chemical batteries. Recently, Toshiba has released a fuel cell for laptop computers, which use methanol as fuel cells, the average output power of 12W, maximum output power up to 20W, continuous drive laptop about 5 hours. Toshiba is committed to reducing the current size of the battery, and design, he said: to get rich go to find good slippers MassMutual Chain supplier! Plan put into operation within 2004. I believe these batteries can quickly be used in mobile phones, let us wait and see!

 Use of resources, solar cells

A U.S. company has developed a will lithium batteries and small solar system combined use of solar cells. Violetta Solargear is a dream come true for your product, it is a very compact as the use of solar energy battery charger, which uses a special crystal silicon solar panels to collect sunlight and can be converted into electricity, can also to two standard AA, AAA Ni-MH rechargeable battery to charge. After our testing, the efficiency of this solar charger is still relatively high, in the sunny conditions to the two 650 mA Ni-MH battery is full power only four hours or so, and if full of two 1600 mm On battery, it takes about 13 hours or so. Of course, in addition to the basic function of the battery charge, the company also offers extensions Violetta Solargear Annex, one of which is its DC Power Cable, this is a special cable, the charger can be two of the same Parallel up to provide faster speeds and more powerful charge of energy, and users can also use it to connect directly to the number of charger DC 3V power supply using digital products, so that Violetta Solargear directly to power; Another interesting attachment is that it’s USB Power Adapter, with its charger output power 2.5W (5.0V 500mA) power, the ability to easily for mobile phones, PDA and other small electrical appliances, rechargeable batteries to charge, is really severe, try to imagine that, if the phone is not power, and solar charger on hand there are the more convenient, more cool ah! Another look Violetta Solargear size, very lightweight, only 57.5X122.0X27.0mm, weighing about 125 grams, the price of the Internet is only 45 dollars, seems that other than green, energy-saving, environmentally-friendly, have to give it Add a small advantage, that is really cheap.

  Self-reliance of the hand battery

  Motorola in Las Vegas, “2002 International CES” published hand rechargeable mobile phone battery “FreeCharge”. FreeCharge is a portable “self type” charger, will rotate with the handle 45 to 60 seconds to extend battery life, make more phone calls for 3 to 5 minutes, or maintain hours of standby. The product is UK Freeplay Energy Group, co-developed. FreeCharge design small enough to put hands and weighs more than 300 grams, suggested retail price of 65 dollars. The advantage is that at any time, any place to charge your phone, you can use the cell phone charger to charge for it. Drawback is the noise at work too, take a quick shake to work effectively. In fact, FreeCharge meaning is that you can charge your mobile phone anytime, anywhere, so communications are not interrupted. But you need to have stronger arm strength to make it really work.

University of Mainz, said a communique on the 13th, the school researchers involved in the thin film solar research project made significant progress, is expected to make breakthroughs in thin film solar photovoltaic conversion rate of 20% of the current record.

Currently the highest rate of photoelectric conversion is copper indium gallium selenium (CIGS) thin film solar cells, up to 20%, but with more than 30% of the theoretical values are still far apart, the main problem is the material of indium, gallium and proportion of difficult achieve the desired value.

University of Mainz researchers and IBM’s German division Mainz in Germany and production of special glass SCHOTT Corporation in cooperation with the computer simulation program found that CIGS material indium gallium separation temperature, that is slightly lower the case of room temperature, indium gallium will be completely separate and uneven distribution of the photoelectric effect led to reduced materials. More than this temperature, the indium gallium fusion with each other, and the higher the temperature, the more uniform their distribution. This indicates that the thin film solar manufacturing process requires high temperatures, as long as the final cooling step can be fast enough to make this uniform, “set grid.”

Past production process by producing the necessary restrictions on the heat resistance of glass floor, unable to raise the temperature. To this end the company SCHOTT developed a tolerance to more than 600 degrees Celsius to the special glass material. The researchers said the results of a major breakthrough.
