American University in Mechanical Engineering and MIT materials science and engineering researchers in the June 21, 2010 announced the development of a lithium-ion battery with a new carbon nanotube electrode material, which is based on nanotubes surface functional groups of the oxidation-reduction reaction. The electrode a few microns thick, allows reversible lithium storage capacity of up to weight of 200 mAh g-1 electrode, also available electrode power 100 kW kg -1, cycle life of more than several thousand times the performance and electrochemical capacitors can be comparable to the electrode.

    Stacked layer assembly for the electrode, the electrode was in no additives, high density and function of the composition of multi-walled carbon nanotubes. The facility to use carbon nanotubes as a cathode electrode, lithium titanium oxide as the anode, the weight of energy than conventional electrochemical capacitors to 5 times higher than the power output than conventional lithium-ion batteries 10 times.

    Its performance due to good electrode conduction of ions and electrons, and the nanotube surface and efficient lithium storage.

    Although this electrode can be used in small portable devices at first, but further research will be used for larger applications

Researchers at the Massachusetts Institute of Technology believe they may have found a way to dramatically increase the longevity of laptop and mobile phone batteries . The scientists believe that by replacing the electrodes used in normal batteries with electrodes plated with carbon nanotubes, it may be possible to significantly improve the power to weight ratio of the battery. The result could be dramatic, with the potential to enhance the longevity of batteries in mobile phones, netbooks and notebooks by as much as ten times.

The batteries can last longer as a result of the carbon nanotube batteries being able to store more oxygen groups and being more porous, meaning the battery can contain a larger number of lithium ions. At present, carbon nanotube production remains limited to niche suppliers, but several companies are believed to be preparing for mass production of the material.

Computer manufacturers have long since been attempting to find ways of enhancing battery performance without compromising the portability of laptops, while the recent advent of more advanced mobile phones has broadened the usefulness of this latest finding.

Platinum Yang solar resume trading yesterday, shares surged more than 3 percent once the maximum to see 0.91 yuan, mainly because the company announced that private clean energy generation and the Mainland Chinese enterprises signed a sales contract can be controlled, can sell to the Chinese totaling 2.55 billion U.S. dollars (about 19.8 billion Hong Kong dollars) of thin film solar module production equipment. In addition, the Chinese will be able to subscribe for 1.17 billion Hong Kong dollars Solar Platinum Yang about 49 million shares, representing Platinum Yang has been enlarged share capital of 51.5%. In other words, Han Yang can be a big addition to platinum customers, will be the majority shareholder.

Platinum Yang formerly engaged in toy business, red hair group, to 4.18 billion yuan in October last year bought a company engaged in manufacturing thin film solar PV module production line of specialized equipment and the company’s 80% interest, which involved transformation of solar energy business, as its main business for the PV component manufacturers to provide equipment and production lines, so could that be in the upstream industry.

In fact, want to talk about today is thin film solar cells, solar power system has three type of batteries, including crystalline silicon, thin film and concentrator, which is the mainstream crystalline silicon, such as silicon and polysilicon. Polysilicon Zengyin demand, prices have been pushed up to 500 U.S. dollars / kg, has dropped to about 50 U.S. dollars / kg.

Although solar energy is considered clean energy, but the polysilicon refining process is energy-intensive and high pollution. The principle of thin film solar cell is made of a layer of thin film solar cell, the silicon is extremely rare, or do not use polysilicon, it can reduce the production costs and reduce pollution.

Thin film solar cells available for some time actually, but because of the low photoelectric conversion efficiency than silicon, so I did not universal, but as technology advances, photovoltaic conversion efficiency has been more than two years ago to upgrade 30% to 40%. According to statistics, in 2005 the total solar thin film solar cells, cell capacity of only 5% last year, its share has more than 20%. Thin film solar cells is becoming increasingly popular, will limit growth in demand for polysilicon.

Concern of BYD Co., Ltd. The first Daimler new electric vehicle power systems have been identified. Last week, the reporter learned from BYD Auto, is expected to 2013 models listed in the joint venture with the BYD E6 battery will be used as the iron battery.

BYD car battery joint venture with Daimler will use BYD independent research and development, “Green Core” ET-Power-iron battery, follow the electric vehicle power systems e6. Previously, BYD said in a joint venture company to provide automotive power core technology, the global Daimler CEO Zetsche has publicly stated: “BYD is China’s new energy leader in the automotive field, the phosphorylation of BYD Lithium Iron Bidaimule currently used more advanced lithium batteries. ”

This year in May, Daimler joint venture agreement with BYD formally signed a joint venture with Daimler-new Technology Co., Ltd. Shenzhen BYD plans to launch in 2013 a new electric car, caused widespread concern in the industry. At that time the two sides said the joint venture will combine the development of electric cars Daimler electric cars structure and safety in the field of proprietary technology and BYD car battery and drive technology.

In addition to the joint venture company to promote electric vehicle research and development, the BYD electric cars began to consider raising the sales program this year. Last week, deputy general manager of BYD Auto sales company, said Wang Jianjun, will increase the pace of industrialization of electric vehicles, 2010, 1000 original electric vehicle production target will be raised, the specific plan is needed to further raise market research. According to the New Deal, BYD F3DM or by 50,000 yuan of financial subsidies, e6 is or will be up to 6 million worth of financial subsidies.

According to research reports that lithium car will bring an energy revolution and industrial revolution. Major automotive and battery businesses have invested in building car lithium ion battery production line, concentrated in the 2010-2011 production. NiMH batteries will continue to mainstream status in 2011, but after 2011, lithium batteries will gradually erode the market share of NiMH batteries. But who in the international standardization of next-generation automotive lithium gained opportunities to master certification initiative, and the enterprises will benefit immensely.

Comprehensive information on all aspects, lithium batteries will be the future development of new energy vehicles more worthy of reliance on the power source. New energy vehicles will move “Ni-MH - Lithium - The fuel cell” industrial development path. Lithium-ion battery in three years despite the nickel-hydrogen battery replacement is difficult, however, can not be ignored is that lithium batteries will replace the nickel-metal hydride batteries coming into the mainstream of the new energy vehicles.

Held in Shenzhen this year, a capital forum, a number of representatives, the new energy battery or will be important to invest venture capital, holding this view reason that the current difficulties of Electric Vehicle’s bottleneck is the battery, and battery bottleneck cathode material and the diaphragm is present, the two have made a great breakthrough in China, and has independent intellectual property rights. The huge domestic demand and national policy support to make this new energy battery market prospects fame, venture capital is no reason why the Nuggets are not optimistic about the treasure.

Favored by venture capital than lithium in the field, back in 2008, the amount of money to invest in thin film solar led to straight up. Lenovo, Intel, International Finance Corporation (IFC) and other venture has to thin film solar industry funding, mainstream names from these enterprises, you can capture the changing situation of the sign industry.

Data show that investment in the wind mechanism of the United States led the world last year in the first half to invest in energy storage batteries, the total capital of 100 million 14 million U.S. dollars, is the two speed over the same period the previous year. According to industry estimates, the battery industry to promote investment in the United States will continue for some time in the future.

Moderator: Let’s now look at the electric car technology is more advanced lithium-driven, including before, Tesla will do some sports car, is to use lithium batteries, although to achieve a long life time. It may only be lithium batteries, but also more than 1,800 lithium core. Do you think electric cars lithium battery will be a major technical means?

Schkade: as I am not a battery or a lithium-ion battery experts. So, now I can not say lithium-ion battery is not the best solution, is not the most should be used in our new energy automotive industry as a way of them. But I know that most of the advanced battery technology is still on the lithium-ion batteries. Many of the companies the possibility of future battery development and R & D efforts are now concentrated in the lithium battery research. But lithium is not a simple one, as you just said 1800 core that, in fact, many, many lithium batteries for various automotive products. In the lithium battery, there is a nickel-hydrogen batteries, lithium batteries may not be as advanced technology. Now why there are different battery technology? Because some areas are not rich lithium resources, how to do that lithium batteries? Lithium is not a rich resource for the area concerned, to mass production of lithium as fuel for another decade or two decades, this is a problem we need to face. In the end, the problem is the development of lithium batteries are lithium-ion battery technology itself, or because we are not lithium resources, it is not clear. I think that is a double problem, first because the need to develop lithium-ion battery technology, and the second is now available lithium resources, we can not, we do not have enough battery raw materials. This is a further problem, we take a look at over time, lithium-ion batteries will become a leading, in the future be able to solve a wide range of battery solutions for various problems.

Yu Hongtao: Judging from the periodic table inside, or the most advanced lithium-ion battery technology a. But tell the truth, the current lithium-ion the hands of human technology in order to truly achieve large-scale commercialization of electric vehicles still have some distance. Therefore, in our industry are scientists, including some of the new technology is more than this generation of lithium-ion battery technology more advanced technology to do some new energy vehicles energy, such as reported in the previous paragraph I see a number of cars in the study Lithium-air battery, once it can form after the industrialization of its energy density is almost comparable with petrol.

Moderator: Now many companies are developing electric cars including the use of lithium batteries, but take into account the life cycle of the battery in the future after the end of the degradation of its pollution of the environment is greater than the existing internal combustion engine?

The Tao: This is a very important issue, it relates to the future, the lithium-ion battery industry. Realistically speaking, at present the whole industry, including government research on lithium-ion battery more effort is placed on how to improve the performance of lithium ion, and how to recover, if the guarantee lithium-ion batteries for future use is over does not affect the environment, this area is relatively less studied.

Schkade: lithium-ion battery technology is just starting, right after its environmental impact, which I personally do not clear, I am not a battery technology experts. I think the battery degradation, recycling, the environmental impact of this point, it needs further consideration, to be seen. Now its impact on the environment, pollution how, there is no definite answer. I think even the battery expert in now or ask a number of technical experts, he has only to give some of his personal views. After the concrete reality of pollution for what he could do nothing to give you a very accurate answer. SAE speaking to us, our job is to convene the world’s experts in automotive technology, come together to discuss means of finding solutions to car problems. In Shanghai in October this year, our Center for Automotive Research SAE and electric vehicle battery joint summit forum, it is certain that a considerable part of the discussion focused on the environmental impact of batteries and recycling issues, to the time that many experts to discuss this. If we are very concerned about this issue, then, to join or pay attention to our SAE battery summit will be a very good option.

Moderator: SAE or on the Center for Automotive Research in China, is considered such a program is responsible for selling off the train car, the battery provided by other manufacturers. To enter the charging station when it can not replace the battery charge, such a program?

Schkade: automobile production cars, batteries for recycling is a very good solution, which is now in the end is the best way, is hard to say. The way you just mentioned is a method, we have other ways to solve this problem, for example, this battery in your car outside, consumers rent the battery is also an option. Because in terms of electric vehicles, more central part of the battery if you want to dispense with the need to meet a lot of cars on the battery requirements, including the acceleration, the exercise of cars, the car’s performance on the battery requirements. If the battery after a period of time no longer fit to drive, you can use this battery to the other. Such as the electric field of the stored energy, or some other industries which can be used. I say this example is not to say the future will do, but would like to assure you that such a model, the market if they have such an opportunity, entrepreneurs may find the opportunity of a new industry emerged. Through the success of these methods to find a suitable business model, the battery problem will be solved. It does need a lot of work. This is my personal view, this is a very exciting for us commercially.

Yu Hongtao: charging now there are many global practice, including fast charging and battery replacement. Battery replacement in this manner have a larger problem that the size and the size of the battery there is no way unified. For example, the bus probably easier to unity, because it put the battery in the space more rules, but also relatively large, can put the battery the battery design of its space. For the average passenger car in terms of different cars put the battery space, shape, size is not the same. Therefore, this replacement battery in a different car when very difficult to achieve, which is affecting the battery replaced a bottleneck in this way.

According to research reports that lithium car will bring an energy revolution and industrial revolution. Major automotive and battery businesses have invested in building car lithium ion battery production line, concentrated in the 2010-2011 production. NiMH batteries will continue to mainstream status in 2011, but after 2011, lithium batteries will gradually erode the market share of NiMH batteries.

Electric car needs a new technology for the automotive industry Lirun provide new ways of development in electric vehicles to occupy more positions, grab more work will undoubtedly get more profit, and this is business and vehicle Auto parts suppliers focus of the next battle.

In the past many years, automotive suppliers in the automotive development has gradually occupy more control, essentially covering 75% of the vehicle development costs, however, the trend of interest makes the vehicle must at all costs, companies want to reverse this trend, but now in full swing for the development of electric vehicles, control the development of technology will undoubtedly become the focus of contention between the two sides.

“For electric vehicles, the vehicle enterprises account for relatively large share of the engine without a gear box, also banned, added an electric motor and most important - the battery. The French parts maker Valeo electric vehicle development departments people Henri Trintignac says.

“Suppose monopoly suppliers of electric motors, electronics and battery production, vehicle manufacturing enterprises in the cost of a car share from 25% to 10% down, I do not think they can accept the situation. ”

Renault - Nissan CEO Carlos - Ghosn is the battery electric vehicles to become “the core of the entire electric vehicle manufacturers.”

On the electric vehicle manufacturing cost is expected to vary, but a more consistent view of the battery in the electric vehicle will occupy one-third of production costs or even one half of GDP.

Nissan Leaf electric car will be available in Europe early next year, while the Renault Kangoo and the Fluence will be available after a few months.

Ghosn that ended in 2020, electric cars could account for the entire industry, 10% of new vehicle sales, however, many other apparently more cautious estimates. HSBC analysts estimate will account for the light electric vehicle market share of 4.5% of the car.

In last year’s Frankfurt Motor Show, Ghosn said: “We do not rely on others, we are going to independent producers (battery). To other vehicle manufacturers to provide the battery is not a problem.”

Nissan would like an independent production company that vehicle batteries, and many enterprises had to rely on cars and professional supplier of joint ventures, relying on its complex and specialized technical skills necessary to develop this gold mine.

Nissan, NEC Corporation of Japan have jointly developed for LEAF hatchback lithium-ion battery, while the German Daimler currently has with the Chinese battery maker BYD to cooperate.

Pool maker Saft’s Chief Executive John - Seville, said some car manufacturers have begun to consider from the supplier to recapture something.

Barclays Capital analyst Christina agreed to accept the car manufacturers will not be completely certain technologies, “monopoly supplier.” “I think they (the manufacturers) of course, want to make sure they have some control over development.”

“They do not want to simply outsource, because they know that, at some stage in the future some technology will be key to winning and the core.” She added.

Because vehicle enterprises also tend to enterprises through joint ventures or partnerships to maintain some control over technology, and will advance the Touzi Bijiao high, the electric car run, will be yes for the supplier rather than a cause simply for Ying Li Feng Xian Project. Christina continue their analysis.

Seville warning that the vehicle will be found to overthrow the existing enterprise system, the process of developing new fields is full of hardships, particularly in relation to the complexity of battery technology.

“According to the Western model, in addition to engines and gear boxes, almost all of the key components are the vehicle from the parts supplier companies acquired.”

“We think this is a lot of Western car manufacturers will continue to follow the pattern, because this is undoubtedly easier, they do not need massive investment.”

IHS Global Insight analyst, said Tim, in view of an electric vehicle parts and components needed to countless vehicle companies and suppliers will be the relationship between the occurrence of “dramatic” changes.

“Electric car market includes not only batteries and electric motors, lighting, heat and air conditioning systems, all of which must meet one of the best optimizing system.” Thus, while control technology profitable, but the risk of them have a clear Awareness is also very important, especially in early stage investment in battery technology.

BCC research firm has forecast report issued by large and advanced battery technologies Di global market value will Zai in 2009 to 6% on the basis of a comprehensive annual growth rate, and will be 近 2014 to 11 billion U.S. dollars.

The largest part of the market for portable products involving advanced batteries, such as laptops, portable tools and lawn care and battery. Advanced fixed cells representing the second largest market. Representative of the third-largest market for mobile applications.

The first “solar house” has high-tech zones in Changsha Lugu. By Changsha climate characteristics, this “solar house” self-produced 15 kWh per day, day or night, sunny rain, home electrical appliances can use solar power. Battery storage capacity can “meet” three or four rainy days. However, the villa investment of nearly 1.1 million yuan, due to high costs, solar power also extended to the apartment building long way to go.

Comments: The building is a monument of human civilization. The first “solar house” While there is still this kind of problem, it is hard to promote. However, this green building construction ideas may be brewing another revolution. Process in the future, building a harmonious ecological environment and a good low-carbon, comfortable, convenient, beautiful personalized modern homes, is the architect of the big issues in today’s world.
