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 ...

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 ...

Forward-looking: Despite being a relatively rare element, lithium is still the king of materials when it comes to rechargeable battery technology. Calcium is 2,500 times more abundant than lithium, ...
