U.S. scientists have invented a new "paper battery", 10 times the efficiency of lithium batteries
Someday, lightweight battery with an ordinary paper production, is being slowly disappear to print e-mail, e-books and online news reading devices to send and power.
Stanford University in California, scientists have said in the report, they have been successfully coated with a layer of silver nano-materials, carbon paper, into a "paper battery" light is expected to become a new and efficient method of storage. Help coating attached to the same features make it a piece of paper attached to the single-walled carbon nanotubes and silver nanowire film. Preliminary studies have found that the use made of silicon nanowire battery efficiency is now used to power devices such as notebook computer lithium-ion batteries 10 times.
Scientists published in the "U.S. National Academy of Sciences" on a paper said: "The use of sophisticated papermaking technology, through the paper with conductive as the collector and the electrode can be made into low-cost, lightweight and efficient electrical storage devices. "
People can use this battery for hybrid electronic devices, or energy. Using this battery, electronic devices will become lighter, lasts longer, and may one day produce paper and electronic products. Weight and battery life is the power cars and trucks in the commercial development of a major obstacle encountered.
Materials Science and Engineering, Stanford University associate professor and co-authors of this paper Cui Yi (Yi Cui), said: "Our society really needs a low-cost, high-energy storage devices such as batteries and super capacitors simple." Yi Cui that, in addition to portable electronic devices and wearable electronic devices can use it outside, "Our paper can also be applied to all super-capacitors require instantaneous power energy equipment. Because of our paper, the cost of batteries and super capacitors is very low, they also applies to the energy reserves of the grid. "University of California, Berkeley, chemistry professor Yang Peidong (Peidong Yang) said the technology will be commercialized in the near future.
Days of storage batteries into the South African market can
Recently, the South African solar manufacturers to days to study group, and live day to purchase solar energy storage battery group.
South Africa is the largest producer of electricity, before power has been adequate, cheap electricity, but the last two years, frequent nationwide electricity shortage. National saving as an important measure, the South African government in May last year the country began actively promoting solar energy, issued a series of preferential policies, vigorously popularize solar power, solar energy and solar lights and other traffic lights.
The South African companies to come to China, aims to select high quality solar energy storage batteries. Related businesses in the domestic field trips several times after the final selection of days to the South African company Group. Storage battery manufacturers in South Africa ordered the first batch of products will use solar power system in South Africa, the future South African National solar, wind and lighting systems engineering in the gel used in storage batteries are directed to the Group from the days of purchase, while days to the South African Group provide comprehensive technical support and after-sales service.
LG's first solar cell production lines start mass production next January
South Korean LG Electronics (LG Electronics Inc.) 22 said Monday's first solar cell production line from January 2010 to begin mass production.
October 2008, the electronics companies have said the end of 2010 a total investment of 2,202 billion won, the construction of two solar cell production lines and templates.
LG Electronics said in a statement in 2011, the factory will start in the second large-scale production.
