According to the National Center for Light Detection monitoring report shows Nanfu “shaped ring” cells in MP3 music player can play 21 hours straight, electricity is a common high-capacity inspiron 1525 battery to 6.6 times.

Recently, U.S. researchers are jointly developing a tiered solar thermal hybrid solar Dell vostro 1500 battery , combine the solar photovoltaic cells and the thermoelectric materials to absorb light and heat , two different forms of solar energy. Meanwhile, the U.S. Department of Energy is also hoped that the solar cells are made into wooden tiles, in order to contribute to the environment. To achieve this goal, the Department of Energy to the United Engineering Corporation allocated 150 thousand U.S. dollars of funds to help it for the first phase of research and development.

The company is currently working with Columbia University in New York. The researchers hope that the roof solar Sharp md-mt831 battery panels solar thermal hybrid solar conversion efficiency can reach 12%, although the efficiency is not high, but considering the low cost, is still attractive. At present, models produced: In the solar panels under the outermost layer of protection is a photovoltaic solar cells for Casio np-100 , followed by the researchers referred to as “functional upgrades sandwich”, and from the plastic tube composed of thermoelectric materials. Plastic Header Pipe into the cold water cooling panels to play the role of outflows into the hot water heating for people to use. In the plastic tube below the bottom of the battery plate: plastic strengthened stories. Photovoltaic solar cells to solar electromagnetic radiation into electricity, while the thermal layer of solar thermal energy will be converted into electricity. Researchers presented, plastic pipe “feature upgrades sandwich” in the whole hybrid solar panels plays an important role, especially in the summer, the solar Dell inspiron 6400 battery temperature is too high, the conversion efficiency becomes low, this time plastic pipe cooling device The role will be very obvious.

Right now, other than the battery for Sony np-f330 were tested on the laboratory of Columbia University , they will be tested in New York, Douglas College (FDA) a roof area of 6.4 square meters of construction . The researchers also calculated the cost of the technology to generate electricity, which is determined that a new energy technology can compete with fossil fuels, the most basic standards.

This are the first stage of the experiment. If the success of this phase, researchers will be 6 months into the second stage: one million U.S. dollars from the Department of Energy to obtain funds in a year the technology was further improved. After the third phase is likely to cost 10 million U.S. dollars for the solar battery , Sony np-f730 technology, commercial production. Some studies presented, and they wanted to end within five years, the technology will go into market.

U.S. Department of Energy said they were very supportive of the plan. Solar cell for Sony np-f750 has not been able to penetrate into the market, mainly due to the initial high cost, conversion efficiency is low, but the solar thermal hybrid rooftop solar panels are part of the building’s surface, and the efficiency has been improved. At the same time, these low-cost, durable akku panels is extremely suitable for installation in ordinary residential and commercial buildings, the wide range of uses and broad prospects.

Continue to innovate and leap

China’s power Dell Latitude D620 Battery development is accompanied by the growth of electric bicycle stems. However, beginning in the domestic lithium-ion battery electric vehicles to carry out research and development, the lithium-ion battery and there were some explosions.

Generally speaking, batteries and battery safety is inversely proportional to the energy stored, namely, the greater the available energy released, the worse its safety. Huang Xue-Jie said, in other words, and in inverse proportion to the weight of the battery. Of course, as the battery size increases, the thermal performance deterioration, the possibility of an explosion is a significant increase, so will be made of lithium-ion battery power battery, it must improve its safety performance; the use of the larger, its demands also achieved higher safety index.

Lithium-ion Dell Latitude D820 Battery explosion, a very important reason is that the use of mobile phone batteries commonly used lithium cobalt oxide as cathode material for lithium-ion battery. Lithium cobalt oxide materials, theoretical specific energy of more than 270 milliamperes per gram of time, but to ensure its revolving nature, the actual capacity available than the theoretical capacity is only half that at about 140 milliamperes.

“In the actual use of the process, if in some unexpected circumstances, such as the management system damage caused by the battery charging voltage is too high, then the remaining part of the lithium will be from the anode through the electrolyte to the cathode surface in the form of lithium metal deposition. “Huang Xue-Jie said that, while the underpotential deposition of lithium on the surface can easily form a” dendrite “, thus piercing the diaphragm, the positive and negative short-circuit, causing fire and explosions accidents. In addition, the lithium metal is very lively, melting point is also low, the battery temperature is too high or partial contact with the shell broken air cases, very dangerous indeed.

Search for alternative cathode material for lithium cobalt oxide to solve security problems is the production of lithium-ion Dell Inspiron 6000 Battery power the optimal first consideration.

“Tenth Five-Year” period, in the 863 Program, supported by CAS Institute of Physics has developed lithium iron phosphate oxygen vacancies and for the vehicle power battery lithium manganese oxide cathode material, they developed a proprietary surface modification technology be applied to modified into the spinel lithium manganese oxide materials, produced when the reversible capacity of 107 milliamperes per gram, 55 ℃ cycle capacity retention rate of 200 times greater than 90%, better than similar products in the international levels and to protect the electric vehicle major projects in high-power lithium-ion batteries the smooth progress of the project. Pilot plant in Shandong Province on the basis of the technical fujitsu lifebook e8110 battery craft, built in Wuxi, an annual output of 1,000 tons of production lines.

In the lithium-ion battery anode material for research and development, our country also has significant progress. As a cell phone lithium-ion battery anode material of choice for middle-carbon micro-balls, our country has to achieve a comprehensive localization. Shanghai Shanshan and Tianjin Tiecheng production of the type of anode material, which were reversible capacity of 300-340 mAh / g, performance indicators have reached or in part, exceed international advanced level, and the price is only two-thirds of imported products . But the graphite anode materials can not meet high-power hybrid cars and long-life requirements, Huang Xue-Jie said, in the power fujitsu lifebook e8210 battery, the use of a graphite structure, mesophase carbon micro-sphere there is a fatal flaw, namely, the impact of high current when the As the volume change, carbon surface of the solid electrolyte layer of the ball will be damaged, thus accelerating the decay of its life. In the 863 nano-specific support, the Beijing Star Constant successfully developed a hard carbon anode materials, Badachu Hi-Tech Park is located in the pilot line is expected to put into production later this month.

The safety of lithium-ion battery materials

More than 10 years ago, the lithium-ion canon nb-4l battery is only scientists in the laboratory sought-after piece of scholarship.

Today, the people’s lives almost without it. Mobile phones, portable computers, almost all portable personal electronic equipment must be relied on to provide the required energy.

But how to put it in the car, and became a driving force of motor vehicles; how to access it to become the future power of the “container”, the scientists began to explore constantly, the battery “magnanimous” to a growing, dynamic to Yue Lai is stronger, life expectancy should be longer, but it does not mean that the size and weight but also growing, this is not simply the number of overlay .

The key to this change is that the casio np-20 battery material. The materials used in mobile phone battery must not be used to make electric cars the “heart”, or is not likely to explode, but will certainly be trouble.

Thus, scientists from various countries are trying to find the best answer.

20 years, insisted that something out of nothing

Physics Chinese Academy of Sciences research fellow and doctoral tutor Huang Xue-Jie evaluation of the development of China’s lithium-ion batteries are: from scratch, from small to large, developed rapidly.

In 2000 China’s output of about 20 million, accounting for 3.6% global share, with South Korea close to a time when Japan had reached an annual output of 512 million, accounting for 93.9%. 2002 China crossed the 100 million in 2004 reached 760 million, accounting for 37.1% of the global casio np-100 market, after Japan.

China’s lithium-ion battery research and development projects has been the focus of 863 items, from mobile devices with small batteries started 20 consecutive years of support. At present a small lithium-ion battery has an annual production capacity of more than 200 million, Japan, SONY, Sanyo and other companies to build production plants to China. Most of these materials achieve localization and the introduction of multi-national has been self-built production lines and supporting materials factory, there are many months, have been the formation of large-scale production and market competition.

“Small battery and its related materials, current technology processes mature into the scale of production, mainly to promote industrial investment.” Wong Hok-chieh.

“China’s power battery research relatively late, but so far has made remarkable achievements.” Huang Xue-Jie said that after 20 years of Physics, Chinese Academy of Sciences to study the accumulation of storage in nano-phosphate lithium anode materials and cathode minolta np-600 materials research in China ranks world-class.

China’s power type lithium-ion batteries “15″ electric vehicles during the 863 major projects with the support of research and development began to address the issue of high power output, security has also been greatly improved, relying on the CAS Institute of Physics Technology Suzhou Star Constant Power Co., created to achieve a flat battery mechanized production, in 2004, Suzhou Star Constant R & D of 10 AH high-energy-type and 7.5 Ah high-power-type manganese lithium-ion battery has passed the United States UL safety test, becoming the first Chinese mainland by a UL-certified Li-ion power battery, the current bulk supply of products have been domestic and international markets. The development of 15 high-power battery, when an electric vehicle 863 major projects through the organization’s unity test, “15″ period has been successfully applied to the fuel cell sony np-f970 hybrid electric car concept car “Beyond II” and “Beyond the Three.” When an eight high-power battery has become the “Shanghai” brand fuel cell hybrid car standard.

“Car lithium-ion battery technology development and other high-end products, not just the development of China’s electric car industry needs, will also bring China’s lithium-ion digital camera battery industry, a comprehensive technical upgrades.” Wong Hok-chieh.

A substantial expansion of lithium-ion battery – Fujitus Battery

A Japanese company has recently developed a new lithium-ion Fujitsu Lifebook T5010 Battery manufacturing technologies, the use of silicon oxide, nano-silicon, carbon and other materials generated by the new battery anode, so that battery capacity than the currently used graphite as anode in lithium-ion batteries to increase 2 to 5 into.

Silicon has a low price and the absorption rate of lithium-ion and high, suitable for manufacturing large-capacity battery. However, silicon absorbs lithium-ion when the expansion rate is also high, as the battery of negative cracks easily, thereby shortening battery life. Therefore, the silicon material of the lithium-ion batteries have not been able practical use.

According to “Nikkei Business Daily” has reported that fujitsu lifebook t4220 battery Hitachi Maxell, Ltd. adoption of new technologies, so that nc-Si dispersed in the silicon oxide materials is the formation of “nano-silicon-containing compounds” is then mixed with this kind of “nano-silicon-containing compounds” and carbon materials, form a “nano-porous silicon composite material.” This material increases the space between the nano-silicon to solve the battery charging inflated nanometer silicon to make silicon material for battery anode feasible.

The researchers said that this new type of battery capacity than the use of graphite as anode in lithium-ion batteries to increase 2 to 5 into. However, the new battery is about 300 times, there will be a clear decline in charge capacity. At present, the use of graphite as anode of the battery charge is about 500 times, the charge capacity only decreased significantly. Hitachi Maxell plans to further improve new materials to address the issue of a new fujitsu lifebook t4215 battery charge life.
