Hydrogen fuel cell R & D was a major breakthrough
British scientists have invented a lithium compound
laptop battery, can store enough onboard hydrogen fuel cells so that they could drive vehicles driving 300 miles straight. This new technology for future fuel vehicle market is of great significance, because the existing hydrogen storage technology can not do this.
Fuel cells are electrochemical reaction using hydrogen and oxygen to produce clean energy, it does not produce carbon dioxide. However, due to the hydrogen storage technology restrictions, the current fuel cell-powered vehicle prototypes and demonstration models can only reach a maximum travel distance of 200 miles. The standard temperature and pressure, if you want to store enough hydrogen to travel 300 miles in the distance, you need a volume equivalent to double-decker

fuel cells; while other methods, such as compressed hydrogen stored in cylinders inside or will liquefied hydrogen is stored in tins, are due to weight and size issue can not be practical.
As a result, the United Kingdom UK-SHEC project team of researchers another way to try a higher density of hydrogen storage, but will the battery weight control within an acceptable range. They used "chemical absorption" method, the inhalation of gas molecules between the lattice of solid compounds in case of need no longer be released. Research team carried out tests on thousands of compounds in order to find a lightweight and inexpensive materials, such material must be able to in a typical fuel cell operating temperatures, so that the hydrogen adsorption or desorption fast, secure manner. Now, researchers have the system a series of lithium hydride compound, can be well positioned to meet those requirements.
The project coordinator, University of Oxford Professor Peter Jonathan

lifebook t4020 battery Edwards said, "This is the fuel cell industry and the transport sector the long-awaited breakthrough, the key breakthrough will make fuel vehicles in the next 10 years, mass production and application of as possible. "
Promotion of fuel cell is also a "hydrogen economy" of the key technologies. It's environmentally friendly transportation is particularly important potential applications, can present a large number of oil-fuel vehicles to reduce carbon dioxide emissions. At present, a gasoline fuel vehicles an average of about 3 tons of carbon dioxide emissions.
Luoyang Suntech, the development of solar cell manufacturing base
Yesterday went to high-tech zone is located in Luoyang Suntech on the way, the reporter found that the street lamps along the way are not the same as ever, an increase of one block above the beautiful silver square plate. By Suntech found here are exactly the same street. Deputy General Manager of Lan Qin told reporters: "These lights are used in solar energy, side-board is a block of solar panels produced in Luoyang Suntech."
"With silicon is king, who mastered the polysilicon grasps the lifeblood of the solar energy industry." Suntech in the U.S. the New York Stock Exchange immediately after the development of the vision to invest in Luoyang, in Luoyang, a second solar cells production base.
Suntech is a keen vision of policy makers. Suntech 1 construction was in full
lifebook t4210 battery,
FPCBP155 fujitsu battery swing in January 2006, when implementation capacity 6.5 MW. In October 2006 the company launched a 90 MW solar cell expansion project construction, mechanical and electrical installation of the current project has been completed and started trial production in June, when the Luoyang Suntech company can achieve an annual production capacity of 120 megawatts, is expected to be achieved this year, sales revenue 15 billion. Luoyang Suntech solar energy industry, the national statistics on real output second only to Suntech.
In Suntech's clean and spacious workshop, automatic coating machine is a piece of side length 12.5 centimeters, the thickness of the battery is only 220 micron layers of blue-chip coated with a thin film. Plant production supervisor Fu-Kuo-chung, said: "Do not underestimate these thin solar cells, it was covered in full of scientific and technological content. Just plated with a layer of film that can greatly increase the battery efficiency of absorption of sunlight."
Suntech Corporation's "Solar Energy Engineering Technology Research Center" built a world-class chemical laboratory, physical laboratory, lithography laboratory, the proliferation of laboratories, equipped with world-class R & D and testing test equipment. "Center" class at home and abroad gathered photovoltaic technical experts and professional technical personnel, independent research and development of highly efficient crystalline silicon solar cell industry cost of key technologies, engineering technology, PV modules, photovoltaic systems engineering technologies, applications integration and other international and domestic photovoltaic technology, high-end technology, core technologies with independent intellectual
lifebook t4220 battey property rights more than 30 items, access to national science and technology projects 9, provincial and municipal science and technology projects 14.
Company person, in December 2008, Luoyang Suntech industrial scale of the project will reach 150 MW, annual output of 130 MW of crystalline silicon solar cells, the cumulative sales revenue may reach 30 billion yuan, net profit of 300 million yuan, the total tax 65 million yuan. Luoyang Suntech Suntech will be after the domestic solar photovoltaic industry, the largest enterprises, and in the high-performance thin crystalline silicon cells an absolute majority share of the market share.
Xinjiang Seized 10000 infringement total nearly 180,000 mobile phone battery
Xinjiang kunjirap Seized thousand pieces of mobile phone batteries infringement
Xinjiang News May 28 Xinhua recently by Motorola, Nokia, China confirmed that Customs Khunjerab Pass of Xinjiang had uncovered a thousand pieces of counterfeit mobile phone batteries all the infringing products
lifebook p1510 battery,
lifebook p7120 battery.
It is understood that this year, May 6, a Pakistani visitor to the Khunjerab Pass customs for export of mobile phone batteries. Customs officers found the battery when in the identification unclear brand identity, packaging, simple, rough look, a suspected infringement for counterfeit products, so make kept pending. The inventory revealed that the battery installed in the nine sub-boxes in a total of 11960, which brand batteries Nokia 7000, Motorola brand batteries 3100, Samsung brand batteries 1860, amounting to 179.4 thousand yuan.
According to the owner confessed that batch cell phone batteries on April 16 this year in Guangzhou, Urumqi, Xinjiang sent after purchase, and then transported to the Kashgar prepared by kunjirap exported to Pakistan's port city of Karachi for sale. It is reported that in Guangzhou buy the mobile phone battery is only 10-12 yuan, to the Pakistani market can fetch around 80 yuan. The difference between inside and outside the market, allowing the operators to purchase a large number of violations at mobile phone batteries in an attempt to Khunjerab exit ports, and reap high profits.
Khunjerab Pass Customs withheld the cell phone batteries immediately wrote to Nokia, Motorola, Samsung and other companies in China headquarters to confirm the authenticity of these cell phone batteries.
The case is now being processed. Khunjerab Customs indicated that in light of this situation, the customs inspection staff will enhance the
pavilion zd7000 battery,
pavilion zd8000 battery entry and exit of goods and passengers checking luggage items, guard against infringing goods entering and exiting, effective safeguard the legitimate rights and interests of intellectual property rights.
