Leshan has the natural advantage

Leshan has the natural advantage of the dell laptop battery mineral resources, its production of polycrystalline silicon and monocrystalline silicon R & D strengths, seven years ago, Motorola has attracted foreign entry. This year is the Leshan City “project in”, investment and create, Leshan has become a hot spot for economic development and focus laptop battery. 30, an investment 3 billion yuan, covers an area of 400 acres with the silicon industry closely related to the project signing ceremony was held in Chengdu.
Over the years, Leshan foster a base, resources, and has been the formation of 100 tons of polycrystalline silicon, monocrystalline silicon 60 tons and 20 tons of production capacity of silicon processing. Today in the energy shortage, silicon resources Leshan finally got “useless.” Nantong, Jiangsu and Sichuan Leshan strong enterprises of the two places together, the project formed after the introduction of the dell GD761 battery silicon industry chain — polysilicon and monocrystalline silicon products “solar photovoltaic (battery)”, will greatly meet the needs of China’s western region power supply. Expected to be fully completed in 2008, its products “photovoltaic” sales will reach 2 billion yuan. Then a new “Silicon Valley” will rise in the west.
Tsinghua University, carbon nanotubes have been new breakthroughs in hydrogen storage technology research
Carbon nano-materials, Tsinghua University research team recently found a post-processed to show a significant hydrogen storage properties of carbon nanotubes, it is expected to become a new clean energy - hydrogen energy dell KD476 battery material.
Study Group on the orientation of scientific and technical personnel of the electrochemical hydrogen storage properties of carbon nanotubes to carry out a systematic study found that the carbon nanotubes have a number of new mechanical, electrical, thermal and optical properties, in particular, it mixed with copper powder After showing remarkable performance of hydrogen storage. Sub-topics will be made from carbon nanotube electrodes for electrochemical constant current charge-discharge experiments, results showed that copper powder mixed directional multi-walled carbon nanotube hydrogen storage dell TD347 battery capacity of the electrode is 10 times the graphite electrode, non-directional multi-walled carbon nanotube electrodes 13 times as high capacity 1625mAh / g, corresponding to hydrogen storage capacity of 5.7wt% (mass fraction), has excellent electrochemical hydrogen storage performance. According to the U.S. Department of Energy (DOE) hydrogen storage technology for the development of vehicle standards, the research team published the results have been dell Inspiron 1000 battery close to the weight of hydrogen storage materials and hydrogen storage density requirements.
This technology can be applied to the manufacture of fuel cells, the sustained and steady play the role of the hydrogen source. Is a fuel cell without combustion to electricity for the fuel in response to the chemical energy directly into electrical energy generating device. Of these, proton exchange membrane fuel cell (PEMFC) in pure hydrogen for fuel, with low operating temperature, output power, and small size dell Inspiron 2200 battery, light weight, “zero emissions” the advantages, in particular the use of suitable means of transport.
Inspection and quarantine to remind: import battery to be filed
A few days ago, a company Zhangjiagang imported from Germany 2 test battery Zhangjiagang Inspection Bureau was ordered to send back.
March, Zhangjiagang inspectors examine the import in the forklift when the forklift is found that these batteries as a power source. In accordance with the provisions of the AQSIQ, all battery products in the import inspection and quarantine agencies to apply for the record, the record made before the import of books, and the battery does not import the record of private imports. Accordingly, the Board made the decision to deal with dell 312-0292 battery returned.
Battery products to enhance the prevention and treatment of mercury pollution, protect and improve the ecological environment in China in 2000, AQSIQ issued the “Import and Export Inspection mercury batteries regulatory approach.” The “solution” provides the record imports of battery products, the applicant (manufacturer, importer or the import agents, etc.) the battery should be the products they are importing to the relevant inspection and quarantine agencies to apply for the record. Inspection and quarantine institutions to the structure of the battery, the electrochemical system, as well as mercury in batteries comprehensive test results to determine whether the filing requirements, without a record to ban the import of battery products.
Entry-exit inspection and quarantine departments to remind the Chinese enterprises to strengthen national policies and regulations related to learning and research, did not understand the policy to avoid the occurrence of “illegal” behavior, which to the normal production and operation of the impact and lead to unnecessary dell INSPIRON 2600 battery losses.
Growth of ZnO by the progress
Mechanics, Chinese Academy of Sciences by researchers using vapor deposition method, has successfully synthesized a variety of micro-morphology of the ZnO nano-materials, such as nanowires, nanorods, nano-cone, four feet, such as nano-ZnO, but also the realization of nano-ZnO in carbon nano - direct the growth tube, and prepared a variety of unique morphology of the ZnO micro-nano-materials by this method from synthetic materials are highly luminescent properties and catalytic activity.
Quasi-one-dimensional nanomaterials with a quantum size effect due to a number of specific physical, chemical characteristics, is to examine the conduct of electronic transmission, optical characteristics and dell INSPIRON 2650 battery mechanical properties, such as the size of the physical properties of an ideal system, in building nano-electronic and optical devices has a lot of potential applications are widespread attention in recent years. Unique nano-ZnO quantum size effects, interface effects and the coupling effect of its UV laser, optical waveguide devices, light-emitting components, surface acoustic wave devices, solar cell window materials, varistors and gas sensors have a wide range of uses, referred to as “third-generation semiconductor materials.”
Recently, the United States, “Applied Physics Letters” notice of Mechanics, the nano-zinc oxide (ZnO) growth and characterization of the work of the contributors were formally employed APL, and the text of the picture as the APL of May 8, 2006 cover a picture (Cover Image dell 1G222 battery), note the growth of ZnO nano-mechanics which work to achieve dell 1G222 batterysubstantive progress.
