Most of everyday consumer electronics products are using lithium-ion battery-powered Fujitsu FPCBP63 Battery, such as mobile phones, MP3, cameras and notebook computers. Before 2007, lithium-ion battery gives a good impression of stability. But in the past few years, there have lithium-ion batteries explode enable the industry to re-examine their security problems and trying to find a new power supply materials.
Foreign media reported that Taiwan's Industrial Technology Research Institute recently found a new solution is still powered by lithium-ion batteries, but not an explosion. It is reported that Alex Pang, led by the research team developed a process known as "Stoba" The new material, can be used in lithium-ion battery between the positive and Laptop Battery negative.

When the lithium-ion batteries as the status of an internal short occurs, the internal temperature will quickly rise to 500 degrees, resulting in lithium-ion batteries overheating or explosion, which Stoba new material you can when the temperature reaches 130 degrees to form a protective film isolation layer, This is to avoid further enhance the stability, in order to avoid an explosion, hence the addition Stoba materials, batteries, also known as "never exploded battery."

However, the current problems is the inclusion of Stoba IBM Laptop Battery will raise the cost of lithium-ion battery, about 2% -3%, the promotion will encounter resistance. Alex Pang said that the new lithium-ion batteries in notebook computers and cell phones in the first use of the first quarter of 2010 is expected to be seen.
Japanese electronics giant Hitachi Ltd. said Monday it plans to sell 418 billion yen (47 billion) of new shares and convertible debt financing in order to improve the poor financial situation. Hitachi said it plans to sell 318 billion yen of new shares and 1,000 billion yen in convertible bonds.

The public offering will be the company's the first time in 27 years, but also will make its shareholding diluted by 30%.

Chloroplasts of green plants through photosynthesis, which convert Laptop Battery sunlight into chemical energy. Inspired by photosynthesis, scientists are working to develop a theory of chloroplast was similar with the new battery - dye-sensitized solar cells, it can convert light into electrical energy, a true "zero emissions."

PV industry as a new force in the field of energy has become a high-tech industries in Jiangsu, one of the fastest growing. However, as the representative of clean energy, silicon solar cell industry chain upstream silicon raw material is high energy consumption and high pollution industries. To this end, scientists have started preparation of new materials developed to use more solar cells.

(According to China Association for Science News Network)

For the photosynthesis of green plants, we may not be familiar: The chloroplast, absorb and utilize light energy, carbon dioxide and water into organic matter stored energy and release oxygen.

Throughout this process, as long as there is sunlight, photosynthesis can always continue.

Called "dye-sensitized solar cell (hereinafter referred to as DSC)" works with the principles of photosynthesis is similar. The difference is that the photosynthesis of green Toshiba Satellite A75 Battery plants through chloroplast, DSC of photosynthesis, using chlorophyll is similar to the dye to absorb sunlight, produce electronic, electronics no longer be collecting electrode, and then through the external circuit and return to counter-electrode to generate photocurrent.

Such cells are considered to be the field of solar energy research and development of another "Dawn." Nanjing University of Technology, Professor Feng Xiaodong recently told reporters that the battery will be the next generation of low-cost solar cells. If the battery proved to be successful, will allow the use of clean energy into millions of households.

Bright have electricity?

"The whole cycle, as long as there is sunlight, and with the external Toshiba Tecra 8000 Battery circuit connected to, we can continuously convert the energy charge." Plasma Physics, Chinese Academy of Sciences Institute DAI Song-yuan introduced the battery works: When the dye molecules absorb the After the sun, electronics became active as well as from the original ground state, and titanium dioxide oxidation reaction occurs, the electronic soon went to electrode surface of the collection, pass out circuit; while returning from the other side of the electrode electrolyte ion electrons captured, sent back to the oxidized dye molecules, to regain back to the ground state, which complete the electron transport cycle.

However, Feng Xiaodong also said, DSC photosynthesis and plant photosynthesis different. Chlorophyll molecules in plants can be said is that DSC used in the dye molecules in kind. It is with the similarity of plant photosynthesis is light absorption, molecular excitation by charge transfer. Difference is not the same as a later step, the DSC run is collected in two electrodes to pass over the charge to generate electricity; while photosynthesis, charge transfer to the reaction center, forming new chemical bonds, it will light equipment for into chemical Toshiba Tecra 8100 Battery energy.

Geometric new battery cost?

"DSC producing simple, low cost, environmentally friendly, and can be prepared on flexible substrates." Feng Xiaodong introduced, compared with the silicon-based solar cells, as the preparation of thin-film photovoltaic cells of the DSC is very simple, it was one of the major advantages of the battery .

In addition, DSC's abundance of raw materials, low cost and stable performance. Cell production process is mainly a large area screen-printing technology and simple immersion method is conducive to large-scale industrial production, and all raw materials and production processes are non-toxic, pollution-free, the battery in the conductive glass can be fully recovered, the protection of environment is important.

DAI Song-yuan said that as the DSC can be directly solar energy into electrical energy, large-scale photovoltaic power generation, to solve China's vast central and western regions without electricity energy issues of great significance. He worked out an account in the long run, if the DSC down the cost of 10 yuan per peak watt, the cost can be considerable with conventional Toshiba Tecra 9000 Battery energy sources. If the efficiency of 7% per square meter will have a 70-watt battery-powered, then an area of 14.3 square kilometers can reach 1000 MW of power supply capacity.

New battery bottleneck where?

For PV to become an integral part of future energy systems, the key is to achieve its cost performance with conventional energy sources can be quite. Dai Song-Yuan introduced to DSC's cost advantages, such as 6% of the photoelectric conversion efficiency, outdoor stability, to achieve more than 10 years, it has the potential for industrialization. But the DSC, as a prolonged period of time outdoor installations, will be a variety of natural conditions. Therefore, the study of long-life, high stability of the DSC is a very pressing issue.

Feng Xiaodong noted that the dye-sensitized solar cells Another problem encountered is the dye molecules, at present its light absorption efficiency is not high enough. Exposure to the spectrum of sunlight on earth is very wide spectrum, 49% of the energy concentrated in the infrared light, while the vast majority of dye molecules present on the infrared light absorption efficiency is not high. Therefore, high absorption efficiency of the synthetic dye molecules have also become a very important research Toshiba Tecra 9100 Battery direction.

Would replace silicon-based solar power?
In 2004, industrial research, DAI Song-yuan of the research team in a leading position in China. They prepared a large area tandem cell module (15 × 20cm2) of the initial efficiency of 5.9%, stability, efficiency of 5%. This industrial production for the next step and lay a good foundation.

He explained, DSC's next main objective is to process and industrial manufacturing technology, strive for new breakthroughs, focused on solving the battery long time stability and improve the efficiency of the battery components, once the popularization and application, require at least 15 -- the stabilization period of more than 20 years. But in the long run, to be truly low-cost solar cell applications, so that ordinary people can afford is the key way out.

Feng Xiaodong that the photovoltaic cells will be in the future become an important safe and reliable new energy. DSC, as a kind of photovoltaic Toshiba Satellite 1900 Battery cells, has its unique application market, of course, it can not replace the current silicon-based solar energy dominance.
