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 ...

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 ...

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 ...

The field of lithium-oxygen battery research is advancing rapidly as scientists explore avenues to capitalise on the ultra-high theoretical energy density offered by this technology. Researchers are ...

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 ...

Chemists have discovered the key reaction that takes place in sodium-air batteries that could pave the way for development of the so-called holy grail of electrochemical energy storage. Chemists at ...

The development of aprotic lithium-oxygen (Li-O 2) batteries with ultra-high theoretical specific energies has been severely hindered by sluggish reaction kinetics and undesired parasitic reactions.

Lithium-air battery technology looks to have a big future. With the potential of providing energy densities up to three times that of the conventional lithium-ion batteries found in just about every ...

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 ...

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 ...
