China Solar Grade Polysilicon supply of emergency

Xuzhou in the silicon industry, the parent company can be co-Xin PV, CEO Jiang Yu noted that the demand for heating due to solar cells, recently sony vaio vgn-fz battery, sony vgp-bps11 battery has been the supply of emergency upstream polysilicon pressure, coupled with the mainland began to limit the import of overseas wafer, while the 2010 tender years, the project has now reached 2GW (20 billion watts), so that estimated solar Queliao problems will continue,notebook battery, but before the end of the price of polysilicon can be also steady.

Solar cell industry in the global financial crisis, “frozen” until the third quarter of this year, entered the industry after the peak season in Europe, the United States needs a stronger, coupled with the mainland government has increased its support for solar cell industry, following the launch of “solar roofs subsidies plans, “planning in Dunhuang, Inner Mongolia and Xinjiang build solar power plants in remote areas, it has even announced in July,” Golden Sun demonstration project on the implementation of the notice “and therefore holds many lessons for excellent demand. Jiang Yu also disclosed that at present in the silicon toshiba pa3475u-1brs battery, toshiba pa3476u-1brs battery industry will be able to sell how much how much more pressure on existing capacity emergency.

Looking up, Jiang Yu analysis, mainland China Ministry of Environmental Protection recently notice the “adjusted import of waste management directory”, which was to restrict imports of products, including semiconductor wafer scrap, head to tail material, etc. This is definitely the upper limit of silicon solar crystal material, the silicon wafer is imported, even if we wanted to import, they have to wait 3 months approval time; Furthermore, the mainland, more and more standard case of solar energy should be gradually released, which in 2010 also identified the tenders to reach 2GW Therefore, the mainland shortly upstream polysilicon solar cells will always be in a “not sold” under the predicament.

Offer more than silicon in the third quarter, demand stabilized, the current price per kilogram has rebounded to more than 60 U.S. dollars, Jiang Yu Queliao problem that will not improve before the end of this year, so the price of polysilicon by the end of the year will not be too much change. As for the silicon industry can be part of, recently also announced its own cost about 36 U.S. dollars per kg from top to bottom, it will continue to profit at the next stage dell latitude d630 battery, dell latitude d830 battery.

To tie in with the mainland market’s strong demand for polysilicon, coupled with the silicon industry in the mainland authorities to “support industry to set up solar power plants abroad” policy, fostering, has made Europe and the United States and other places around 400MW (4 million watts) of the contract, at the same time Xuzhou Economic Development Zone will be set up 20MW power plant, in the silicon industry can continue to invest in expansion of polysilicon end of this year’s largest annual capacity of 1.8 million tons, as the continent’s largest and Asia’s largest polysilicon supplier but also crowd in the world three makers.

As for the silicon industry to customer base in Taiwan, including green energy, the Sino-US crystal, Taiwan, Holley Group is one of its main agents. It is noteworthy that in the silicon industry is also able to move toward the vertical layout of solar cell industry, branched out into a long crystal, pull rod and slice operations, the first quarter of next year’s production, maximum capacity late next year in terms 2GW hp probook 4311s battery, hp pavilion dm3 battery, next year’s actual output is also up to 1GW .

Experts Answer automobile battery

electric vehicle battery as the heart of the performance of the car plays a role. The lithium-ion batteries, lead toshiba pa3534u-1brs battery, toshiba pa3535u-1brs batteries, fuel cells … … these cells differ? Performance between them is it? This goal, we ask the Zhejiang University, Professor of Chemical Engineering and Materials Science, Dr. Wang Lianbang.

Professor Wang has 15 years of research degree battery, Inspiron E1405 battery , studied in Japan, the main attacks of lithium-ion batteries, fuel cells and other new energy technologies. In recent years, Professor Wang has been working with our province and battery tech companies such as Zhejiang day to a close working group to develop lithium-ion batteries and solar power hybrid cars.

Professor Wang told reporters, all companies launcher pure electric vehicles using lithium-ion battery as the main driver of the car. Currently, lithium ion battery carbon cathode materials are generally, but are mainly four kinds of cathode materials, namely, cobalt oxide, manganese oxide, lithium iron phosphate and lithium materials and ternary. lithium cobalt oxide and carbon materials with a lithium ion is mainly used in mobile phones, dell lithium manganese oxide and ternary materials made of carbon materials with lithium-ion batteries used in power tools, the iron phosphate and lithium dell studio 1535 battery, dell studio 1737 battery from a combination of carbon materials lithium-ion has been used in the car, also known as lithium-iron or iron drum.

As the lithium iron phosphate is expensive, more technical difficulties and manufacturing, the price of lithium-ion high, leading to the current high prices of electric vehicles. He stated that the production of lithium-ion very demanding, it is particularly sensitive to moisture, so it must be with good equipment and plant conditions and highly skilled workers to produce lithium-qualified ion. VGP-BPS8 , Existing range of lithium-ion battery with advanced foreign technology is mainly the quality of raw materials, equipment, the gap between the quality of skilled workers. Thus, in this context, there is no large investments for equipment and quality raw materials, companies can not produce the quality and reliability of energy lithium-ion batteries.

Lead-acid battery is commonly used in dell studio xps 1340 battery, dell studio xps 1640 battery electric bike. Professor Wang as “particularly strong vitality” to describe the lead-acid batteries. He told journalists, lead-acid batteries as early as 150 years ago, invented, and for a while we think its almost been eliminated, but thanks to the development of Chinese industry of electric bicycle he was a young man “second”. Changxing province of the nation’s largest producer of lead acid batteries, which represents over 43% of national production.

Lead-acid battery has the advantage of being cheap, the battery itself, its price is only one third of the lithium-ion fifth may be large discharge current, “float” properties, often used as a car battery there is an uninterruptible power supply for the communications industry or the provision of reserve power.apple battery, The disadvantage is that the manufacturing time polluting, low energy density weight, the life expectancy was short, and the battery inside the active material utilization is low toshiba pa3475u-1brs battery, toshiba pa3476u-1brs battery, typically only about 35%.

International Battery Exhibition and academic summary

National support policies will continue to follow up: the new energy vehicles has risen to national strategies toshiba pa3475u-1brs battery, toshiba pa3476u-1brs battery, constantly promote is undoubtedly a follow-up will also have the support of the policy adopted measures, “New Energy Auto Industry Development Plan” prepared to consider the State Department reported early in July, until after the completion of all preparatory work will be implemented, “planning” mainly from the research and development production, marketing, service and recycling in various sectors starting to develop an appropriate industrial policy, fiscal policy, tax policy, Investment and Financing Policy. On the current state of technology, the lithium battery is the best choice for car, all face forward is very positive lithium. Can reduce the production cost of a lithium battery to run the main obstacles to business: lithium battery under current technology, cost and safety has not yet been sufficient to support live data. The use of lithium iron phosphate is considered to solve the current safety, cycle life the best of a cathode material, after mixing elements Meng Meng lithium iron phosphate cathode material will further improve the battery’s specific energy, specific power, if the anode material lithium titanate can successfully replace the existing graphite would further address the safety and cycle life problems, the progress of electrolyte membrane, and also will contribute further. Over time, technological progress, safety and cycle life, the cost will be greatly improved hp mini 5101 battery, hp pavilion dm3 battery.

LEV (light electric vehicles) or for promoting the commercialization of lithium battery pioneer: Domestic electric bike market, more than about 100 million scale, and to increase the annual rate of 20 million, of which 95% are using lead-acid battery, to promote the use of lithium power battery business of a relatively realistic approach is to increase the lithium battery in the LEV, the electric bike, electric motorcycle, the use of small electric vehicles, to obtain certain industrial scale and lower costs . To manufacture the electric cars that replace the traditional internal combustion vehicles, then the lithium battery to meet the cost of 1 yuan / WH, battery cycle life of 2,000 (or 15 years), and the present distance of the target also some gaps. China’s goal is to 2012 to achieve specific energy lithium battery 120WH/KG, specific power 1000W/KG, 2,000 cycle life, cost 2 yuan / WH; to 2020, the lithium battery than the energy to do 200WH/KG than the power 1500W/KG, 3000 cycle life, cost 1 yuan / WH.

18650 cylindrical core VS large capacity lithium batteries square Choice: Domestic including BYD, universal and so were powered by single battery capacity 10AH batteries into the square group, the advantage of group power required will greatly reduce the number of cores, but this square batteries Industry data are inadequate, difficult to ensure consistency, group life cycle after the poor, costs high; abroad, including the BMW is used in such a cylindrical single-18650 body of the battery capacity of around 2AH batteries, such batteries is the general consumer lithium dell studio 1535 battery, dell studio 1737 batteries industrial experience is very rich, better batteries consistency, lower costs, but requires more sophisticated battery management system to control After the battery pack into the group. For square or cylindrical which is more appropriate is inconclusive, we tendentious view is perhaps the 18650 cylindrical batteries larger capacity batteries are commercially square the successful operation of the actual conditions, with greater capacity, square type of technological progress and the cost of batteries down, the future may be dominant.

Lithium battery storage areas or open a broad new world: the market is more concerned about the use of the battery as a power, in fact, the use of energy storage is a broad field of earth. Smart grid energy storage battery as an integral part of both can be applied to store wind energy, solar energy and other forms of instability of the new energy, you can also play the role of load shifting. May adopt a “cascading” in the form of advance, the storage battery due to its storage is static, slightly lower on the requirements of consistency, power battery can continue even after retirement services in the energy storage. However, the lithium sony vgp-bps9 battery, sony vgp-bpl9 battery on the uses of large-scale commercialization of Li-ion battery recycling is still a problem to be solved, this point is not current technology maturity, such as lead-acid battery recycling.
