Lithium-air battery nirvana comes nearer

A decade from now, we could all be driving low-cost electric cars for hundreds of miles without recharging, thanks to an advance in lithium-air battery technology announced today. Or maybe it’ll be some other lithium-air innovation. Or maybe we’ll see batteries with a different chemistry, such as sodium-air or sodium-lithium.

“The battery of the future is going to encompass a lot of these different technologies,” University of Cambridge chemist Clare Grey told GeekWire.

Grey is the senior author of a study describing a technological twist that promises to remove some of the obstacles that have blocked the path to battery nirvana. The research, featured on the cover of this week’s issue of the journal Science, shows how changing the nanostructure of the electrodes and shifting the chemistry can boost a lithium-oxygen battery’s efficiency and make it more stable.
