In September a new national standard should be made from time to time raised the threshold of the implementation of lithium batteries

August 5th, reporters learned from the new energy Aucma, presided over by the company to amend the “cell phone use lithium-ion batteries total norms” national new standard for finishing the work has been completed, only to be promulgated and put into effect in September. The implementation of the new standard will allow lithium-ion 6y270 battery, c1295 battery, dell inspiron 500m battery, dell inspiron 510m battery industry in China entered the fast track of development.

Should be made from time to time

In recent years, the domestic lithium-ion battery industry developed rapidly, particularly in the mobile communications industry, the rapid development of the effective promotion of the lithium-ion battery industry. China-made lithium-ion battery in addition to the expansion of scale, in the product performance is also greatly improved, which is the product testing standards, assessment tools has made new demands. This shows that the standard has significantly lagged behind the original, together with the existing national standards for lithium-ion battery standards and international practices a wide gap between the docking with the international standards and there is an urgent need to develop new industry standards.

“Amendment GB lithium-ion battery is in line with the needs of the development of related industries, but also the requirements of their own development.” According to the company Aucma GB amendments introduced Dr. Wu Huikang responsible person, “Li-ion batteries by Aucma GB of new energy and power of God the company in Tianjin amended to take the lead organization. in 2000 the company completed the first draft of our God, since 2004, Aucma new energy in the basis of the draft has been revised. ”

It is reported that Li-ion batteries by Sony since 1992, began commercial. In 2000, the Japanese lithium-ion battery production accounted for more than 95% of the world. In recent years, this pattern has been broken, China, Japan and Korea formed a pattern of one-third of the world in 2005, lithium-ion batteries in Japan’s global market share will be below 50%, China’s lithium-ion battery in the global market share will rise to 20%.

In this regard, China Battery Industry Association, vice chairman of the told reporters that “China’s lithium-ion battery is able to achieve such good results is the relatively complete industrial chain, the core technology to keep pace with international advanced technology, particularly in the material aspects of lithium, substantial progress has been made in our country. ”

The lithium-ion dell inspiron 600m battery, dell latitude d500 battery, dell latitude d505 battery, dell latitude d510 battery for the country the subject of amendments that and mobile communications industry is closely related to the current situation. He pointed out that current mobile phones, notebooks and other products competitive product cost to start bottom, lithium-ion battery prices will be inevitable. Growth in the face of difficulties, lithium-ion battery manufacturers are requested to rectify the chaos of the lithium-ion battery market.

Small factories will be out

In recent years, although the lithium-ion battery industry in China is developing rapidly, but the development is very uneven. At present, the domestic mobile phone battery manufacturers of all sizes more than 200, of which there is no lack of hand-like small factories workshops, backward technology, simple process. These small factories moved to the Li-ion battery market, weeding, not only disrupted the market order for lithium-ion batteries, but also damages the cell phone manufacturers and the interests of consumers.

Wu pointed out that the revised national standard in the industry will be the establishment of a high technical threshold, only those with relatively high technological level of enterprises need to meet the demand, many of the hands of small factories workshops will be eliminated, and some with considerable size and has a technological advantage enterprises will be more space for development.

According to the briefing, with the existing GB biggest difference lies in the fact that the newly revised national standard may be more feasible. Selection criteria for mobile phones of different manufacturers to give effective guidance to enable them to correct choice of appropriate levels of lithium-ion battery.

“In the enterprise, while eliminating the backward, but also to promote the integration of advanced enterprises.” told reporters that those who lag behind businesses to survive, because lithium-ion battery market, the lack of a strong brand, which is China’s enterprises to ignore an important aspect of the collective.

Brand mark

At present, China’s lithium-ion battery companies have not yet a global brand, but benefit from the “15″, 863 plans, the development of lithium-ion batteries has been an unprecedented support to the Shenzhen BYD, BAK, Shenzhen, Shenzhen science and technology, manufacturers such as TCL payment to the rapid rise, and in the global market for lithium-ion batteries a large market share, forming a lithium-ion battery is relatively complete industrial chain.

“China’s lithium-ion battery products have strong competitiveness, mainly in low-cost and their own intellectual property rights. Motorola 1 / 3 of the lithium-ion battery supply by Aucma.” pointed out that although some companies have a lithium-ion dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery core technologies, products, capacity, safety performance indicators have reached the leading domestic level, but consumers are not recognized before. He believes that enterprises should take the initiative to shape their own brand at the same time, changes in consumer attitudes to guide consumers to recognize that the value of brands.

Pointed out that the Government should give businesses some guidance, and purification of the market for enterprise to create a good environment for development. In addition, to encourage enterprises to go out for export tax rebates and other concessions, to cultivate an international brand.

This reporter has learned that China’s lithium battery brands at the plight of non-solvable, especially in hardware there. Internal lithium-ion battery production equipment, mostly from Japan, the equipment is very expensive; and internal lithium-ion battery manufacturers to develop their own production equipment, and technical is not high, the case of different standards. “To participate in international competition, have to rely on the opponent to provide equipment, which is obviously the road of no return.” Said the experts.

Shanghai to open in October to build environmentally-friendly battery power base

Yesterday, reporter learned from Shanghai Bicycle Industry Association was informed that the country’s largest power dell inspiron 6400 battery, dell inspiron e1505 battery, dell latitude 131l battery production base will start in October this year to build, from Henderson, Zhejiang Power Technology Co., Ltd. to introduce the United States, with a total investment of 5.8 billion yuan in new environment-friendly battery power project recently entered into a joint venture in Shanghai R & D and production agreement, the project will start providing the market with an annual 8 million sets of electric bicycle batteries environmentally-friendly new vehicle.

Beijing this fall will be like homemade hydrogen fuel cell car

Changchun City, Jilin Province Some experts suggested that the current development of automotive fuel cell projects, can also be energy-saving environmental protection, and to seize opportunities in the international community and broad prospects.

Experts said that the fuel cell project is within the 863 projects planned, at present, Tsinghua University a1079 battery, Tongji University and the Dalian Institute of Chemical Physics ongoing research. This autumn, Beijing China and the United States will be made like the hydrogen fuel cell vehicles.

The key to fuel cell technology is the hydrogen proton exchange membrane, Changchun City, Jilin Province Institute of Applied Chemistry, has ion-exchange membrane technology, not the lack of hydrogen materials in Changchun. In June this year, Chery Automobile has become the Ministry of Science and Technology took the lead in the first “National Energy Saving and Environmental Protection Research Center of Automotive Engineering,” the base.

Fuel cell is an energy-saving projects, 34% overall efficiency is the efficiency of petrol-driven 3 times 6y270 battery, c1295 battery; At the same time, the fuel cell is an environmentally friendly project, which can achieve zero discharge of pollution, chemical reactions produce only water objects. In national energy security strategy and oil bottleneck constraints, this project has broad prospects.

Experts believe that a fuel cell project is related to the national energy strategies and catch up with world’s advanced level, a major event for its own intellectual property. In the development of this project, at home and abroad rather close in time. At present, China has not lagged behind the targets, the State also funds support, should be similar to the Changchun-based FAW and by such a unit, should be positive for the project.

Magic change coal direct battery power to learn the only way to non-combustion

At present, the scientists developed a new type of coal for fuel cell energy. This battery and traditional methods of coal is not only simple to extract the energy of combustion, so that the utilization of energy has been a substantial increase.

Vibert Douglas, Harvard University, said: “The battery’s basic idea is to find a method of chemical energy in coal directly into electrical energy.”

Vibert said traditional coal burning power plants through the heat, using heat to promote the steam turbine to produce electricity. During this process, 65% of coal energy will be lost.

Prior to this, people will be struggling to find a kind of coal used for fuel cells, but in order to achieve this process must have a temperature of 600 ℃ to 900 ℃ between the dissolved carbonate electrolyte. However, such a high temperature not only to reduce the use of efficiency, but also make it easy to battery corrosion.

Vibert’s new design and allows the temperature at 100 ℃ under power, the temperature of the previous requirement to achieve this temperature is much easier. However, battery energy utilization in the samples was surprisingly low, only 7%. The utilization rate of only traditional methods of one-fifth of the utilization of coal a1175 battery, apple macbook pro15 battery.

This battery is Vibert George White and his colleagues jointly developed by Sezgin. They add toner slurry of iron ions, and then in sulfuric acid from the mixed electrolyte into the battery. In the mixture, the ferric ion by carbon reduction in the fuel cell in a typical reduction - oxidation cycle, resulting in power.

However, Vibert said that because coal is the source of energy for the battery, this battery can not avoid greenhouse gas carbon dioxide. However, if the battery energy utilization by improving the utilization of power plants can not exceed, then the people from the coal seam is widely distributed throughout the world to gain more energy, but also will not be accompanied by the increase of carbon dioxide emissions.

Vibert said, in fact, only very simple and easy to see improvements in battery energy can be greatly improved utilization. For example, the use of higher quality coal, or improvements in the design of the electrode, the electrode _ is taking a closer.

In this regard, the Royal London School of Energy Policy Management Group Matthew Leach said that such improvements to make fuel cells for the opportunity to compete with traditional coal-fired power generation is critical.

Leach also said that such a battery will be used for large-scale power generation units, we should not be attributed to it can be used in the type of car-MH battery. However, he also believes that the advantages of fuel cells is one of the true portability, and this a1078 battery, a1148 battery, apple powerbook g415 inch battery because it is difficult to make a mixture of pulverized coal with sulfuric acid and restricted distribution.

Development of the “dirty silicon” technology to produce new low-cost solar cell

University of California, Berkeley researchers announced the development of a based on the “dirty silicon” (dirty silicon) of the new technology, this technology can reduce the cost of solar cells dell inspiron 4000 battery, dell inspiron 4100 battery, dell inspiron 4150 battery, dell inspiron 8000 battery, dell inspiron 8100 battery. Nearly 90% of the solar cell is due to refining of pure silicon production.

The use of such a richer, cheaper silicon - that is, the existence of metal impurities and defects in silicon - the attempt has not been successful, because the use of this material can not be produced by solar cells to run. In addition, for the elimination of impurities in the high cost of manufacturing techniques, the use of cheaper materials to offset the cost advantage. Berkeley professor of materials science, Weber said: “We propose the use of dirty silicon, a new method.” Weber said: “We are not to remove impurities, but left them, but through a reduction in their adverse effects on the solar cell approach to take advantage of them. ”

The researchers said their study found that will enable more low-cost waste into useful materials, reducing the cost of solar cells. Researchers can detect the use of only 30 nm high-sensitivity metal cluster synchrotron X-ray microscope, an analysis of the metal impurities in silicon for different types of reaction processes. The researchers found that the distribution of silicon material in different locations on the nano-scale defects in limiting the energy loss of electrons can be spread before the average distance. Dissemination of the longer distance, the material on the higher energy conversion efficiency. The researchers found that by changing the cooling rate of silicon to control the distribution of metal impurities. Slow down the cooling rate, the proliferation of metal impurities in the formation of large clusters, thus changing the distribution of impurities dispersed.

How to promote China’s development of solar photovoltaic cell technology

With coal as the mainstay of China’s energy structure of the energy - resources - environmental problems are becoming increasingly difficult to highlight. To solve this problem is one of the ways to develop green renewable energy. China’s abundant solar energy resources, the country had accepted the total amount of solar radiation on average for 5.85 × 106kJ/m2, in particular, the majority of China’s northern regions and Yunnan, Guangdong and Fujian to the south dell 6y270 battery, dell c1295 battery, dell inspiron 500m battery, dell inspiron 510m battery. Utilization of solar energy is an important form of solar power.

According to statistics, by the end of 2003 the country has installed photovoltaic cells accumulated about 55MW. The largest to date in 2004 in Shenzhen China International Flower Expo Garden 1MW photovoltaic power plant system, the successful implementation of power generation. Is expected that by 2020 the total installed capacity of China’s solar cell to achieve 30GWp. Photovoltaic power generation will only China’s total generating capacity of 1%, even so, in order to achieve this objective requires the total installed capacity of solar cells to more than 40% of the annual growth rate. This is China’s solar cell technology is a challenge and an excellent opportunity.

First, the international status of photovoltaic technology

World solar cell production the rapid growth in recent years, from 1999 to 2004, the 200MW of 1260MW. Average annual growth rate of more than 30%. 2004, 2003, based on 69% increase! In the photovoltaic device and manufacturing technology, has been available since the PV cells, crystalline silicon cells as the basic material has maintained a dominant position, so the world around the crystalline silicon photovoltaic technology development in the most mature material. Crystalline silicon photovoltaic solar cells is currently the international mainstream products on the market. According to statistics, in 2004 the battery of crystalline silicon, including monocrystalline silicon, polycrystalline silicon and with silicon cells, the proportion of the world’s solar cell more than 94%. In crystalline silicon cells, from 2003 to 2004 increased the proportion of single crystal silicon, polycrystalline silicon ratio declined. Amorphous silicon in 1999 from 12% to 4% in 2004. The proportion of other thin-film batteries also add up to less than 2%. Table 1 is the world’s major solar cell production statistics. World solar cell production mainly in Japan, Europe and the United States, especially Japan. China has a relatively large increase.

In solar technology research, to reduce costs is quite a long time now and in the future the most important task. The world’s major solar cell-producing countries in the efforts of crystalline silicon solar cells in a series of technical studies.

123

(1) to improve the crystalline silicon, in particular, the conversion efficiency of monocrystalline silicon cells, continue to develop new technologies, such as the University of New South Wales, Australia groove technology and the use of special passivation technology, single crystal silicon cells have achieved conversion efficiency reached 24.7 % dell inspiron 600m battery, dell latitude d500 battery, dell latitude d505 battery, dell latitude d510 battery.

(2) to reduce the amount of crystalline silicon material. Crystalline silicon cell materials accounted for the total cost of production of about 40%. Proceed in two ways to reduce the amount of crystalline silicon materials:

(1) of thin-film batteries. Germany will cut silicon to 40μm thick cells, the conversion efficiency can be as high as 20%.

(2) brought about as a result of cutting of crystalline silicon materials accounted for 50%, so the development of cutting people in order to reduce the deterioration of materials and technology.

(3) to optimize the design of the battery components to improve the efficiency of the battery components. Lower conversion efficiency using a single battery, the battery components assembled battery module efficient.

(4) the life of the battery components to achieve 30 years.

(5) Other technical progress. Including energy storage devices to reduce costs, simplify and standardize the installation of battery systems. A variety of crystalline silicon cell technology development, the highest level as shown in table 2.

124

The realization of thin film solar cells, and is internationally one of the main directions of research and development. Such as directly from the silicon melt out the thickness of crystalline silicon in the 100μm band. It is also studying the use of liquid or vapor deposition, such as chemical vapor deposition method of preparation of crystalline silicon thin film solar cell materials as. Can be used when lower-cost metallurgical silicon or other low-cost substrate materials such as glass, graphite and ceramics. Substrates used in the low-cost low-temperature deposition of semiconductor thin film preparation technology of photovoltaic devices, preparation of materials and devices can be completed at the same time, technology is simple, easy to continuous large-scale production; Preparation of low energy consumption and payback period can be shortened. Without crystalline silicon substrate as the substrate material on the vapor deposition of polycrystalline silicon conversion efficiency has been reached more than 12%.

In addition to crystalline silicon thin-film battery, the other thin-film dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery materials are also making progress. Now is the realization of industrialization and industrialization are amorphous silicon and polycrystalline thin-film compound semiconductor thin-film battery (cadmium telluride, copper indium selenium). Amorphous silicon thin film mainly prepared by chemical vapor deposition. Alone in improving the conversion efficiency of amorphous silicon solar cell research little progress has been made, the current skill level is less than 8%. It is therefore to examine the use of laminated battery technology to improve the efficiency of amorphous silicon, such as laminated battery laboratory a-Si/a-GeSi/a-SiGe reach 15.6% maximum efficiency. Amorphous silicon / polysilicon stack cell (HIT) is a high efficiency of the battery stack. Sanyo has developed a 20.7 percent efficiency a-Si/c-Si battery. CIGS cell research, people trying to use other materials to replace scarce resources such as rare earth elements of the In. In the compound semiconductor thin-film CdTe cells, although the CdTe stability and sound, but the Cd and Te are toxic, some people are trying to study alternative materials. Other compound semiconductor materials have also made remarkable achievements. It is reported that the United States National Renewable Energy Laboratory and the laboratory spectra of germanium substrates in the growth of a GaInP / GaAs / Ge three cell coating, combined with the metal connection and anti-reflective coating, through the standard solar spectrum 1.5AM condenser, was 47 times the intensity of sunlight, resulting in a record 32.3 percent of the photoelectric conversion efficiency. It is estimated that the cost of production of thin-film batteries can be with the expansion of its production scale to reduce, if there is a major breakthrough in technology, the cost can be reduced to one U.S. dollars / WP following. The above-mentioned thin-film battery technology on the study also did not list all the status and trends of the main study. Table 3 is the world of the conversion efficiency of thin-film batteries.

125

It is worth mentioning is that the dye-sensitized solar cells (DSC) has recently made great progress. Large area (100 cm2) DSC conversion efficiency has reached 6%. This type of battery used in the main material for the conductive glass and TiO2, rich source, the battery is also relatively simple preparation process, have greater potential price advantage. However, the conversion efficiency of such batteries to be further enhanced, the stability of the battery to run need to be further tested.

Second, China’s photovoltaic technology achievements

China’s PV cell technology is the 60’s from the 20th century with the development of space solar cells start to develop the ground with the production of photovoltaic cells from the early 70s. After years of efforts, China’s photovoltaic power generation technology has made significant progress, the conversion efficiency of photovoltaic cells continue to increase the efficiency of current silicon cells of 20.4% of laborator dell gd761 battery, dell kd476 battery, dell td347 battery, dell inspiron 6400 battery, production efficiency of 14%, the efficiency of polycrystalline silicon for the 15 laboratories %. Table 4 for various types of China’s current level of battery research laboratory.

126

China’s major low-cost solar cell technology and production capacity is in the 20th century, the mid-80’s built up. After 2000, China’s polycrystalline silicon cells and modules-scale production began to take shape gradually, continuously improve the efficiency of current production. Compared with developed countries, continue to narrow the technology gap. In recent years, to further expand the scope of application of PV. Especially in recent years, affected by domestic and international demand, around the emergence of a number of new photovoltaic enterprises, is worth mentioning that country to fly Shanghai Jiaotong University Green Energy Co., Ltd., batch size of product specifications of the largest domestic, monomer and technical performance and appearance components essential to achieve the quality level of similar products abroad. Monomer plant in the annual production capacity of more than 1MWp, component in the ability to package 5MWp. In large-scale production, China-Australia joint venture Suntech production capacity of crystalline silicon solar cells in June 2004 had reached 50 MW, 75 MW in December to reach production capacity before the end of 2005 to achieve 150 megawatts of production capacity, solar components have reached a production capacity of 50 megawatts, is an international pre-production level of 10. Baoding Yingli New Energy Resources Co., Ltd. has introduced a full set of advanced solar silicon (polysilicon), batteries, components, production lines, annual production capacity of 48 MW.

Third, development of solar Suggestions

Control of our country and the world’s solar cell technology, the overall view, China’s solar technology has made considerable progress. However, solar cell production in China mainly relies on imported equipment. Solar-grade crystalline silicon mainly rely on imports. Technology with independent intellectual property rights is also very small. In recent years, as a result of increased demand on the international market dell inspiron e1505 battery, dell inspiron 1501 battery, competing in many areas and some small-scale photovoltaic component packaging plant, as a result of small-scale, resulting in the battery components in China’s production costs are generally higher than the international standard of 30%. If this trend continues, will certainly weaken the situation of each other. In particular, foreign companies have to enter into China’s entry into the WTO, their capital and technological advantages, it is bound to the rapid occupation of China’s PV market, weakening the development of China’s solar industry. Of course, economic development in the context of globalization today, this view may also need to advance with the times. However, if we do not have independent intellectual property rights of photovoltaic technology, we will always be controlled by others, so great in favor of technology owners. Thus, it is necessary to strengthen the study of photovoltaic technology into the development of technologies with independent intellectual property rights.

425

On the one hand, China’s need to market demand in order to boost the technological development, technological innovation through the enterprise; On the other hand, countries need to formulate policies and technology development planning 417066-001 battery, hstnn-lb31 battery, 411462-421 battery, hp pavilion dv2000 battery, hp pavilion dv6000 battery, hp pavilion dv2500 battery, the promotion of solar science and technology. Demand in the market, in March 2005 adopted a renewable energy law, through various channels to promote and oversee the implementation of the Act. Combined with the development of the west and east of the building, in particular the requirements of energy-saving buildings, photovoltaic market to nurture and promote the formation and development. Solar cells as a result of higher prices in general, it is difficult to form a short-term self-sustainable development. Can refer to the German solar industry experience, preferential loans to install solar systems and higher Internet prices. As a result of the current situation of solar cell roof States plans to pull the market good. Some provinces and cities in China also plans to engage in the roof. With the 2008 Beijing Olympic Games, Shanghai World Expo in 2010, we have the hope that the application of solar cells in China greater access to a breakthrough. At the same time, the Government should set up the relevant management agencies, guide the trade associations, and gradually standardize the production and sale of solar cell market.

427

State and local governments to adopt policies to guide our country with strong economic power of energy companies and enterprises to participate in the development of solar cell industry. Japan, the United States and Europe, with strong economic strength of large companies actively involved in the production of solar cells, China’s largest energy companies are involved in very few.

Government to make people realize that the use of solar cells is beneficial to social development event, at the same time as a result of the use of special price policy, urban regional solar power generation system installed, such as the installation of the roof of the battery system is profitable.

From a technical perspective, the State through the development of planning and increased funding for research to promote an original birth of the new technologies. Combination of the world development trend of solar cell technology, we need to look carefully at our view of solar cell technology development. Deserves our attention is that of crystalline silicon, in particular the production of monocrystalline silicon cells and increased the momentum of development. Need to continue to develop ways to further enhance the silicon photoelectric conversion efficiency of the battery, how to further reduce the deterioration of materials and the cutting technology, reducing the thickness of crystalline silicon cells, the production of ultra-thin crystalline silicon cell technology. To develop the production of crystalline silicon solar cell-grade key equipment and technology. Upstream and downstream in the solar cell technology, including a dedicated solar batteries, battery monitoring systems, test instrumentation systems, as well as the battery system assembly and installation of technology, we also need to give them adequate attention.

Thin-film cell technology to reduce battery cost is the ultimate hope, the need to continue to develop. Thin-film battery should sum up the experience of long-term development and the lessons learned. China in the production of crystalline silicon solar cell-grade level, but larger metallurgical silicon production, metallurgy in the development of silicon-based thin-film polysilicon cell body to do more work. Attention should be paid to other thin-film solar cell research vgp-bps2 battery, vgp-bps2a battery, vgp-bpl2 battery, including new materials and new structure of the battery.

The development of solar technology is the collection of solid-state physics, materials science, materials technology, mechanical and electrical engineering and equipment development of multi-disciplinary and integrated systems engineering technology. Especially in materials science and technology in solar technology occupies an important position. And technology development is inseparable from the cultivation of human resources and inputs, in conjunction with the solar theory and technology, in colleges and universities to foster the development of solar technology professionals and engineers, including the lower reaches of the solar skills. Therefore, I believe that the expansion of the University to participate in the special needs of solar cell research, the formation of solar-related theories, technologies and engineering personnel training chain for China’s solar cell technology development.
