Batteries supply electrons by undergoing reversible chemical reactions. That has meant that all the reactants have to be inside the battery, which adds to its weight and volume. Lithium-air batteries ...

CAMBRIDGE, Mass -- Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output ...

Lithium-ion batteries are often found throughout households, but it is essential to charge and dispose of them correctly to ...

A new type of lithium-oxygen battery could pack more energy and last longer than its predecessors. Lithium-oxygen cells are made of two electrodes, an anode and a cathode, separated by a substance ...

If you’re reading this with a rechargeable battery powered appliance, the chances are it’s a lithium-ion battery based on intercalation chemistry. But with increasing demands for higher energy density ...

Boasting an energy density similar to that of gasoline, lithium-air (or lithium-oxygen) batteries may one day prove the panacea for the range-anxiety associated with electric vehicles. But first there ...

Studies indicate that they occur less frequently than in combustion cars, but the chemistry and battery components make them more intense and require different, and more challenging, techniques to ...

The days of gas-guzzling cars may come to an end before we run out of oil if technologies such as 500-mile-per-charge lithium-air batteries become a real and affordable option. A company that ...

A new kind of lithium-oxygen battery, using glass nanoparticles of lithium oxides, could provide more energy, and much better stability and energy efficiency, report scientists. Lithium-air batteries ...
