CMP (china moblie power) is the abbreviation of China Mobile Power Supply has been committed to China’s new energy research and development and improvement, has nearly a decade of notebook battery R & D and production history and reputation in the international arena. According to the person in charge said: Actually, those from the original brand of  laptop batteries, almost all from mainland China’s foundry business!
The person in charge is advisable for consumers, the choice of laptop batteries  Latitude D620 battery , C1295 , HD438, do not blindly believe the original notebook battery quality, but rather from the battery to distinguish the quality of material and process up the pros and cons.
High-quality batteries in the choice of material demands strict control. Of high-quality materials is to ensure that the battery of high-quality basis. Laptop battery mainly by the COB board, batteries group, protective material, shell and other parts. The quality requirements for all components are very high. Some manufacturers in order to save costs, use of low-quality protection without batteries or electronic components, or save the fireproofing material that one, which virtually all of the battery life and security of hidden dangers.
In addition to the high material requirements, but also in the processing technology on the stringent requirements to ensure that maximize the performance of high-quality materials. For example, CMP, in the production process, in strict accordance with international standards, the production process to produce and carry out full quality control, especially in the batteries capacity allocation, strict and accurate 100% of capacity batteries uniform distribution, in order to ensure that the same batteries Group batteries each have the same capacity, voltage and resistance.
Of course, consumers purchase products can not open the battery to identify the material, then how to choose it? The responsible person said, first of all, a rigorous process control, high-quality batteries must pass the national and international electronic products usually have a certification, such as: 3C, CE, UL, ROHS certification, which is to ensure that product quality prerequisite for compliance.
Second, the regular manufacturers of high-quality manufactured batteries on the packaging requirements are also very high, consumers can feel from the product packaging, writing clear, paste the location of the label to determine the details. Regular, high-quality battery manufacturers of paper packaging delicate, feeling good; packaging printing legible handwriting, no wrong, and missed the word or ghosting; label pasted on the pasting and products seamless tank there will not be posted crooked or posted groove surface phenomenon.
Finally, after-sales commitment of view, a responsible manufacturer must have a formal set of strict after-sales service system to ensure that the legitimate rights and interests of consumers.
Through the introduction of the above points, I believe that consumers easily could have been elected to rest assured that laptop batteries. Person in charge of CMP, said, CMP brand laptop batteries in addition to satisfying all the selection principles, in price significantly lower than the original battery. Even more exciting is that, CMP creative to make all of CMP brand battery warranty period of two years of super-long warranty! And solemnly promise, CMP valuable brand, the battery can be recycled, which is undoubtedly environmentally conscious consumers, to bring all those who love the gospel!

Sharp with 35.8% solar cell conversion efficiency refresh the record

“Efficiency is close to internal combustion engine. This is the conversion efficiency to achieve the ideal of breaking 50% of the solar cells in the process of a major breakthrough” (Sharp). Recently, Sharp,  Inspiron E1505 battery the conversion efficiency of solar cells increased to a record 35.8%. If the condenser to 1000 times the conversion efficiency is also expected to reach 45%.
Sharp’s technical staff the ongoing new round of development. Objective is to 1 / 10 the cost of non-condensing unit when the conversion efficiency exceeded 40%. To go beyond 40% as the goal is not to intensify the development of a Sharp. laptop battery In order to achieve high efficiency solar cells, the technology development of competition are becoming more active.
Prior to this, the highest conversion efficiency is the U.S. NREL (National Renewable Energy Laboratory) in 2007, created by 33.8%. Condenser under the conditions of maximum efficiency Spectrolab is the United States in October 2009 just posted on the Institute 41.6%. Including Sharp, including the results of this and create a record of all compounds for the three-in-style multi-junction solar cells.
The solar cell conversion efficiency to the limit and need to combine different materials band gap in order to take full advantage of the various wavelengths of light. Sharp focus on the past, manufacturing simplicity, chose the lattice constant close to the material. Namely, the top unit (the upper three-junction structure) of InGaP, the unit (ibid., middle) as InGaAs, at the end of unit (ibid., lower) for Ge, bottom of Ge.
This time, Sharp to optimize the band-gap for the first, at the end of unit Ge (bandgap of 0.67eV) from the InGaAs (ibid., 0.97eV) substitution, using InGaP (top), GaAs (China), InGaAs (bottom), GaAs backplane combinations. Therefore, in accordance with the order from top to bottom, from short to long wavelengths of light can be applied effectively to generate electricity.
Solve the issue through the Reverse Cascade
This combination exists InGaP and GaAs lattice constants, and other bottom layer of quite different issues. This phenomenon may give rise to crystal defects, it is difficult to achieve high efficiency. To this end, Sharp turned the film over the past order, through the use of from the InGaP (top) began in turn film “reverse cascade formation method” so that the lattice constant of GaAs substrate basically reached a consensus. Through the lattice constants of the different GaAs (middle) and InGaAs (bottom) inserted between the buffer layer, inhibiting defects. Taking into account the transmission wavelength, the buffer layer and top with the InGaP.
Forming method using the reverse cascading from the InGaP (top) began in turn to the superposition of InGaAs (bottom), the three-layer GaAs substrate need to separate, InGaAs (bottom) layer down to the Si substrate on the transfer. InGaP layer in a direction to the surface. Bonding with the Si substrate to use is “similar to the solder material” (Sharp).
In addition to more efficient, the method can also reduce costs in the future. GaAs substrate separation process is currently used by curettage GaAs substrate method. If in the future to take advantage of plug stripped layer, who wish to divest part of the implementation of ion implantation and other methods to complete the process, then, GaAs substrate is expected to achieve reuse. As the GaAs substrate is very expensive, so the realization of this method can significantly reduce costs.
With these improvements, “than crystalline Si-high two-digit,” is expected to reduce manufacturing costs to the current 1 / 10. Its use is currently limited to satellite, but with lower costs in the future may also be extended to other areas.
Enhancement of conversion efficiency does not stop there. 2025, Sharp plans to develop a cell conversion efficiency of 40%, 1000 times the condenser when the conversion efficiency of 50% of the revolutionary solar cells. Through the InGaAs (bottom) below the addition of new layers, to achieve four resultant compound multi-junction solar cells. Manufacturing methods is still the method of reverse cascade formation. In addition to the different band gap materials, the use of quantum dots band gap control layer is also expected to become a new layer.
South Korea’s LG and Taiwan’s AU Optronics (AUO) is scheduled to “Green Device 2009 Forum” (10/28 ~ 10/30) held on to explore the solar cell business and technology strategy seminar solar cells.

Japan’s Sharp Corporation 22, announced that the application layer of the formation of an innovative technology, the company’s long-term commitment to R & D compounds 3 junction solar cell achieved a 35.8% of the high photoelectric conversion efficiency.
       Sharp’s 22 press release that the compound is different from the current mainstream solar cell silicon solar cells for the material. It more than two kinds of indium and other elements of the compound as the material to form a light absorption layer, Inspiron E1405 battery , Latitude D520 battery the photoelectric conversion efficiency than silicon solar cells, laptop battery is mainly used in satellites.

       Sharp is committed to research and development since 2000 by a three-layer optical absorption layer stack compounds made of three junction solar cell. The past three junction solar cell compounds, the underlying germanium materials are used, although the use of this material will have a great current, but can not be the most current energy use. Another kind of material indium gallium arsenide, can substantially increase the efficiency of current use, but very regular atomic arrangement of production of high-quality indium gallium arsenide is very difficult. Sharp R & D personnel application layer of the formation of unique technology to solve high-quality GaAs layer of the formation of indium problem, so that compounds 3 junction photoelectric conversion efficiency of solar cells from the previous 31.5% to 35.8%.

We are in the market to replace laptop battery, it often to see what those who claim to what is used with an ultra-AA batteries compatible with the battery level what does that mean?

         In fact, purely a propaganda tool, Take the Sanyo to examples of each of the 18650-capacity batteries is very easy to distinguish ways of looking at the color of the battery cover to protect gas will know the capacity size.
Sanyo battery assembly plants provided by the batteries to get after the matching assembly, thus matching the first (mainly the resistance of the pair) and then assembled, in this part inside the battery manufacturers and battery pack manufacturers do not distinguish between What is the so-called A + +. Then, on the market a new 2600mah batteries source of what is it? One is a real battery assembly factory inventories, that is, a certain number of the remaining tailings batteries, battery assembly plants in order to optimize the quality of the battery is generally refuse to use the residual tailings added a new batch of batteries inside the engaged in production; the second, that is, pre-production testing process, I found a variety of factors, does not fulfill the anti-2600mah batteries, but its capacity is significantly higher than the 2400mah batteries. Outside of these two batteries XPS M140 battery , Inspiron XPS M170 battery is a major source of sales of new 2600mah. Therefore, this so-called A + + what the stuff is completely merchants own standards, there is no basis. Moreover, the battery capacity and the English alphabetical order the contrary, B-level is the 2200mah batteries, which is frequently used Chinese-made notebook 4400MAH origin, and the price cheap and the most mature.

         On the resistance of the pair, the battery on the relationship between the good and bad, and if one had the same batteries C1295 , HD438 , D5318 , inside the battery parameters are almost identical in all aspects, then the battery will be able to give full play to the greatest advantage of these batteries, if one of these batteries in some of the parameters a and another a few batteries vary greatly, then the battery can play to its advantages at this time will receive its influence, and the barrel is the same principle to decide the capacity of this bucket is the bucket The lowest piece of wood to decide.

   Not here to use a professional terms, just simply say that a moment principle. We hope that readers can understand!

August 18, 2009, Guangzhou residents of Chiang Chao-An is being charged cell phone battery exploded, his left eye blind deep-fried on the spot.
      August 2, 2009, Yangzhou Yang, cell phone pocket on the trousers suddenly exploded, injuring his thigh.
July 26, 2009, the Fuzhou Railway Village, home of Mr. Zhu living room of a sudden popping sound, a 7 Nanfu battery explosion, DVD machines were scattered around a bombed remote control to … …
      These are some of the recent media exposure of the battery explosion, and even the quality has been good and the Nokia cell phone explosion occurred in New Zealand announced a global recall of events, the occurrence of battery explosions one after another, the safety of lithium batteries KD186 , MM165 , NF343 gradually into the public view.
 
The battery industry crisis triggered an explosion
 
The world’s manufacturing center of the lithium from mainly from Japan to South China in Shenzhen area, two-thirds of the world’s lithium in China, two-thirds of lithium in South China. Shenzhen lithium battery industry after 10 years of development, has become the largest of the second battery industrial base, with a strong competitive edge in the low-end products.
After the incident, the laptop battery  company in Shenzhen how to treat these problems? Turn to what kind of industry self-regulation do? With these questions, this reporter visited BYD, Banke, BAK, Barrett and other well-known battery companies in Shenzhen.
      BAK Battery, Inc. Chief Engineer, told reporters: “driven by huge profits, so that fast tympanites battery industry, the industry’s large manufacturers, mixed low-level duplicate issues is very conspicuous. If the battery is explosive this issue is not effectively controlled, long-term past, will eventually require the battery caused by mobile phones, digital products and other industrial markets shrink, the results also will affect the battery industry development. ”
Currently, China’s lithium battery industry has been formed in southern China as the core of radiation pattern of China’s southeastern coast. But the industry, barriers to entry is low, not high-tech, making lithium battery industry in the rapidly developing as well as trouble. According to statistics provided by relevant units, only in 2008 in Shenzhen on the new lithium Inspiron 6000 battery of more than 100 production enterprises, but also a large number of workshops based corporate failures.
“Shenzhen lithium battery industry is rapidly developing, but it also faces many difficulties.” Shenzhen B & K new energy sources, experts said the financial crisis to hit Guangdong battery industry experience, many enterprises have ceased production, a loss of almost the whole industry. After the financial crisis, international buyers withdrawals, he said, breach of contract, destruction of a single constant. Lithium cobalt prices soaring, China is facing a new round of lithium challenge. For the “dangerous power box” hidden dangers, the domestic 3G Electrical safety standards for lithium-how to fully established? Shenzhen lithium how to cut into the field of high-end brand? These are serious issues.
 
Deep Lithium Electric no longer follow the low-level route
 
     “We all know to improve the safety of lithium batteries is extremely urgent.” Shenzhen BAK Battery Co., Ltd., executive vice president of MAO Huan-yu referring to China’s current industry issues, when lithium pointed out that as the industry has a large number of small workshop factory, to rely solely on a two leading independent innovation of enterprises unable to dominate the industry’s healthy development, for this reason, he strongly suggested that China should establish a lithium battery industry, manufacturing industry standard.
Has been successfully held four high-level forum of the South China Lithium New Energy Co., Ltd. Shenzhen B & K President and Miss Gao Ping, said: “We had some concerns about battery safety held last year, the theme ‘from manufacturing to create’ high-level forum of the South China lithium. convergence of the three places of the lithium elite, concerned about the safety of lithium-power industry and jointly explore the development of China’s lithium plans, and vigorously promote innovation, hoping to find one for the Chinese Lithium smooth the road to sustainable development. She said that domestic enterprises, such as lithium BYD, BAK and so in addition to vigorously carry out independent innovation. Banke batteries  6Y270 , 75UYF have also introduced a thickness of only 0.5 mm ultra-thin battery and capacity 300AH (equivalent to 300 people can use high-capacity mobile phone battery) Industrial Batteries . The representative of China’s current lithium battery research and development of high level.
     Miss Gao Ping said that regulate the industry is essential. July 8, 2009, B & K initiated the establishment of the company led by a “lithium power industry alliance” aimed at industry self-regulation, to China’s lithium production set the rules, norms lithium battery industry order between enterprises operating order to create the industry’s overall development pattern, increasing China’s lithium ThinkPad R60 battery  industry in the global influence so that China’s lithium enterprise onto the international, standardized way.
