Materials scientists have found a way to prevent internal short-circuits, the main cause of fires in lithium (Li)-ion batteries.

Although the supply of lithium around the world is plentiful, getting access to it and extracting it remains challenging and inefficient.

Researchers have developed rechargeable batteries that can store up to six times more charge than ones that are commercially available.

Lithium ions work well for energy storage, however, lithium is an expensive metal with concerns regarding its environmental impact
