British use of the development of new porous carbon air battery life 10 times longer

According to “Science Daily” Web site on May 18 reported that British,PCG-Z505 , scientists have developed a new type of air cells, comparable with the current laptop battery life 10 times longer. This will improve the mobile phone and other electronic products, such as the performance capabilities and promote renewable energy industries, in particular the development of electric vehicles. Even if the weather changes, sun xicheng , this battery can enable sustained wind and solar power devices, “views” remain.

British researchers at the University of St Andrews will be referred to as such batteries STAIR (StAndrewsAir) battery.Sony laptop battery

,
Add them to the battery by the porous carbon elements manufactured to replace the rechargeable batteries Inspiron B120 battery , HD438 , KD186 currently used in the chemical constituents of a lithium cobalt oxide —. These components can discharge the battery when the ambient air from the oxygen to be used in the carbon-hole interaction in the repeated, forming a charge-discharge cycles, so that the STAIR batteries have 3 times higher than that of other cells of the storage capacity.

Because there is no such a lithium cobalt oxide chemical composition, and the batteries currently used in comparison, the same size STAIR batteries Latitude D820 battery , Latitude D830 battery can provide more energy. This electric vehicle industry would be tantamount to a Gospel, because the development of long-standing problems of electric vehicles is necessary in the protection of the premise of the power supply to reduce battery size and weight. At the same time, the use of oxygen rather than chemical agents,VGP-BPS8, STAIR battery battery more than the existing economy. Air is free of charge, while the carbon component is also very cheap, their prices much lower than it replaces lithium cobalt oxide.

The main person in charge of the project, Department of Chemistry, University of St Andrews Peter? Bruce said, our goal is to enable the storage battery capacity 5-10 times, which would far exceed the present level of lithium batteries Inspiron 1150 battery , Inspiron 5150 battery . The current research group is working to make the system suitable for small applications, such as mobile phone or MP3 player battery prototype STAIR. Bruce is expected, STAIR battery of large-scale commercial operation at least 5 years.

The project is funded by the UK Engineering and Physical Sciences Research Council (EPSRC) funding, led the University of St Andrews, Strathclyde and Newcastle researchers are also involved.

The first super block Binodal line silicon thin film solar cells

From Hebei Science and Technology Agency was informed that the first piece of super-large 5.7 square meters Binodal ,PCG-R505,silicon thin film solar cell recently in Langfang City, Hebei Xinao linear photovoltaic companies. This solar cell conversion efficiency of 8%, and significantly reduce production costs.

Solar cells is divided into crystalline silicon cells and amorphous silicon, two major categories of batteries sony battery , dell battery . And compared to crystalline silicon solar cells, including silicon-based thin film solar cells, including the production of amorphous silicon solar cells with low cost, large area lighting, power and good low-light to highlight the advantages. Austrian companies from the new development of large photovoltaic Binodal silicon thin-film solar cell conversion efficiency of 8%, to reach the international advanced level; At the same time, the laptop battery components can be greatly reduced installation costs, lower system cost of power generation and thus avoid the crystalline silicon the production process of high energy consumption, more conducive to energy saving and environmental protection, applicable to vehicle battery charging station, Toshiba Laptop Battery,residential roofs, walls and large-scale power plant construction and other fields, has a broad application space. It is learned that this very large silicon thin film solar cells into mass production soon.
