Water contamination is generally considered to be detrimental to the performance of aprotic lithium–air batteries, whereas this view is challenged by recent contrasting observations. This has provoked ...

A new design could pack more energy and last longer than others of its kind Lithium-oxygen cells are made of two electrodes, an anode and a cathode, separated by a substance called electrolyte. When ...

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.

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 ...

Lithium-oxygen systems could someday outperform today's lithium-ion batteries because of their potential for high energy density. However, a number of important issues, such as their poor ...

TESTING A NEW LITHIUM BATTERY CONCEPT: A discharged carbon cathode viewed through scanning electron microscopy by a team of researchers from Boston College and the Technical University of Denmark. The ...

Researchers at the Chinese Academy of Sciences have fabricated two-dimensional Mn3O4 nanosheets with dominant crystal planes on graphene (Mn3O4 NS/G) as efficient oxygen catalysts for lithium-oxygen ...

Relay Orbital Hybridization Boosts Lithium–Oxygen Battery Catalysis. Schematic illustration of phosphorus-doped MnMoO₄ hollow nanospheres enabling “relay orbital hybridization.” Internal Mo–P orbital ...

Scientists have created a battery whose technology in principle could power electric cars and other energy-hungry devices far better than current lithium-ion batteries, but it remains years away from ...

Researchers are making significant progress in the development of stable and practical electrolytes for lithium-oxygen batteries. Research led by the University of Liverpool, in partnership with ...

Current lithium batteries are based on intercalation—lithium ions squeeze into spaces within electrode materials such as graphite. As a result, most of the battery’s volume and bulk is dedicated to ...
