In recent years, with the electric power, coal, oil and other non-renewable energy sources Laptop Battery frequently in an emergency, energy is increasingly becoming a bottleneck restricting the development of the international economy. The post-petroleum era, so that people will once again focus attention to a new energy development and use of, this has to a certain extent, the promotion of the battery power system industry. People will turn its attention to lithium-ion batteries, fuel cells, solar cells, wind energy battery research and development. According to experts, China's battery industry in terms of technological improvements or in the structure of demand, have ushered in a new era of development.

Fuel Cell

Is not easy to say love you

In today's global energy crisis era, finding new energy as a substitute for fossil fuels is a priority. Because of its easy to get fuel for fuel cells, environmental IBM Laptop Battery protection and sustainable use of the advantages of the battery industry and became the new topic, particularly in the automotive industry in the promotion of pollution-free fuel cell zero emissions, the relevant parties is given a high degree of recognition and evaluation of . In recent years, Europe and the United States, Japan and other developed areas and the state has put a lot of the fuel cell R & D strength, China as early as 50 years in the 20th century to carry out fuel-cell research, is now a key material in fuel cells, the key technological innovation has achieved many breakthroughs. 2008 Beijing Olympic Games on the use of green fleet of 20 self-developed fuel-cell electric cars.

According to the experts predict that by 2013 the global fuel IBM FRU 08K8193 Battery cell market could reach 35 billion U.S. dollars. In 2006, the fuel cell performance will be improved, its sales will also be significantly increased. Fuel cells growing on a global scale, so that many people in the industry that fuel cells will have broad market space, will become a trend in the development of battery industry. However, there are different voices in there.

"Fuel cells can only say that the development of a direction, but not become a trend." China Battery Industry Association, says the Secretary-General Wang Jingzhong. "At present, both foreign and domestic, fuel cells are still in development stage of a trial and did not form a mass, industrialized production." According to Wang Jingzhong introduction, the reason why fuel cells IBM 92P1060 Battery did not form industrial production, mainly by two factors, One is subject to material constraints, fuel cells require platinum as a Coal agent, and such materials costs very expensive. It is understood that the global annual production of platinum in 2006 to 200 tons in 2007 to 220 tons. China's annual output of only about 4 tons and imports about 40 tons, mainly used in chemical industry and chipped jewelry. "Every 50000 fuel cell electric cars would need at least 1 ton of platinum, just from this rare and expensive platinum resources are concerned, how to support affordable fuel cell electric vehicle industry to be?" Chinese Academy of Engineering, YANG Yu-sheng also expressed of the same IBM 08K8214 Battery opinion.

The second is a security risk. Wang Jingzhong that fuel cells are primarily used in the car, then install the bottle whether the quality of fuel to cross the border whether a collision will not occur under high temperature and so on will have security implications.

This year in May, the U.S. government's energy minister Obama officially announced that the government cease its support for fuel cell electric vehicle research and development. The fuel cell electric vehicle has been vigorously advocated by the Bush administration as "hydrogen economy" theory of the "magic." "In the substitution of new platinum catalyst technology has been no fundamental breakthrough in this problem, before fuel cell electric vehicle can not be big development. Moreover, hydrogen is a secondary energy to primary energy consumption can be obtained, the IBM 08K8195 Battery total energy of the fuel cell power conversion efficiency of was not high. do basic research is the key. "YANG Yu-sheng.

Solar energy, lithium-ion battery

Sync with the developed countries

"At present, China's battery industry in research and development of new battery technologies and abroad at the same starting line, just to see who will have a bigger breakthrough." Wang Jingzhong confidently say: "Now our focus is mainly on the lithium-ion batteries, solar cells in the development and research. "

According to Wang Jingzhong New China was founded, China's battery industry is in a destitute condition, the battery is only more than 3000 million total production value of less than millions of dollars in total for the workshop-type enterprises. While 60 years later, China has become the IBM 08K8193 Battery world's first battery-producing countries, production increased by 1000 times, sales revenue increased by tens of thousands of more times, the battery varieties from the new China was founded, early dry and paste-type open-type lead-acid batteries such as several hundreds to the present. Advanced mercury-free alkaline manganese batteries, valve-sealed lead-acid batteries, lithium-ion battery, Ni-MH batteries, solar cells and other products has become China's battery industry's leading products, technologies, equipment, and product quality has been synchronized with the developed countries, China's the battery industry has formed a complete industrial system supporting production and research, are moving toward a world power in the battery industry. As a new energy industry, an important component of solar, wind and other renewable energy sources, electric vehicles and other emerging industries, the rise of China Battery Industry is a new round of take-off and laid a solid market foundation.

It is understood that, after years of development, China's new energy industry has made considerable progress, China's solar cell production IBM 08K8192 Battery capacity has reached 2,900 megawatts, ranking first in the world. The lithium-ion batteries because of its cycle of good performance, high safety factor advantages in electric cars has played an important role.

China Battery Industry Association, Jin-Liang Wang, director of the Technical Committee also believes that the new battery technology is affecting the world science and technology and cutting-edge high-tech industrial development, one of the battery industry is also the most development potential in the 21st century, a sunrise industry, with the rapid development of world science and technology, Battery Industry in China's national economic development will play an increasingly important role. China is now the world's largest battery producer and the largest battery consumption of the country, with oil and other energy crisis escalating, people become increasingly aware of environmental protection, the battery industry is also seeking new opportunities and challenges in the IBM 92P1101 Battery development and breakthroughs

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.

Schematic diagram of lithium-ion battery

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%.

Hitachi said the money raised will be used to add features such as nuclear power, and lithium batteries and other aspects of capacity. Hitachi and General IBM ThinkPad T40 Battery Electric has a nuclear power joint venture.

The company disclosed that as 1000 billion yen in capital expenditure will be the operation of power systems and transportation systems research, and another 30 billion yen will be used to enhance the capacity of lithium batteries, as well as ¥ 90,000,000,000 will be used for software and IBM ThinkPad T41 Battery services business, expansion.

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.

"Artificial leaves" zero emission

PV industry as a new force in the field of Toshiba Satellite 2100 Battery 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.

Nanjing University of Technology, Professor Feng Xiaodong, told this reporter, in which a new type of solar cell, using a good performance, low-cost nano-titanium dioxide as a battery anode, and then a layer of nano-titanium dioxide on the absorption of the sunlight-sensitive organic dye, so they are called dye sensitized solar cells. It is simple and easy to Toshiba Satellite A60-662 Battery get the raw material production, process is not complicated, function as on a leaf, it is vividly called the "artificial leaves."

And leaves compared to dye-sensitized solar cells used in the dye, just as the leaves of chlorophyll, in the sunlight irradiation, will produce electronics, nano-titanium dioxide electrodes are assembled collection of electronic devices. This battery as long as the illumination, it will continuously produce electronics, solar energy directly into the light and will not discharge any waste.

Thin as onion skin, can easily bend

It is learned that, because titanium dioxide has a good visible light transmittance, so this "artificial leaves" almost transparent, and thin as onion skin and can be freely bent, with the materials and device structures of continuous improvement, this magic "leaves" very optimistic about the prospects for commercialization.

According to experts, this transparent "leaves" If you made a large area, it is possible to replace the glass, so long as to receive light, we can provide the impetus indoor small electrical appliances, you can also provide power for outdoor billboards. In the desert plateau, as long as one mounted on its roof fitted Toshiba Satellite A65 Battery with "artificial leaves" big tent, that small cars can provide the impetus for long-distance travel, when people do not need to worry about a lack of fuel cars, but also eliminates the extra baggage travel.

In addition, the flexible and transparent retractable battery is not only comfortable, but also layered, and enhance the utilization of sunlight, in the space area will be the new favorite power spacecraft or satellite.
