Improving high-energy lithium-ion batteries with carbon filler

Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible ...

Shrimp shells to produce electrodes for large storage batteries

A project by Spanish researchers and other collaborators at the Massachusetts Institute of Technology (MIT) suggests the use of chitin from shrimp shells to produce electrodes for vanadium flow batteries. The results of the ...

Discovery challenges accepted rule of organic solar cell design

Solar cells that use mixtures of organic molecules to absorb sunlight and convert it to electricity, that can be applied to curved surfaces such as the body of a car, could be a step closer thanks to a discovery that challenges ...

Dangerous wild grass will be used in batteries

Hogweed, which grows over vast areas of Russia, can be useful as a material for batteries. Scientists from NUST MISIS have investigated the possibilities of fibrous substances in the plant stems. They have turned them into ...

Applying precious metal catalysts economically

Researchers at Ruhr-Universit├Ąt Bochum and the Fritz Haber Institute Berlin have developed a new method of to conserve rare and expensive catalysts and use them sparingly. They enclosed a precious metal salt in tiny micelles, ...
