An efficient lithium-oxygen (Li-O2) battery that can be recharged more than 2,000 times could make truly long-distance electric cars possible for the first time. Chemical engineers at the University ...

A molecule that transports oxygen in blood could be key to developing the next generation of batteries, and in a way that’s environmentally friendly. Lithium-oxygen (Li-O2) batteries have emerged in ...

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 ...

Ju Li, Zhi Zhu et. al. Lithium-air batteries are supposed to lead to lighter, longer-ranged electric cars thanks to their high power-to-weight output, but they have some showstopping flaws: they not ...

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 ...
