The battery’s electrical properties are quite different from other types of lithium-air batteries, but the fact that they can store enough energy to power a phone for months is significant.
A key problem in developing these batteries is that they need a large amount of energy to get going.
As a result, researchers are trying to create lithium-oxygen batteries that are much more compact than those found in smartphones and electric vehicles.
