A breakthrough battery technology could vastly improve the safety of batteries used for electric vehicles (EVs) and could enhance the stability of energy grids, scientists say.

Researchers made the breakthrough while developing solid-state sodium-ion (Na-ion) batteries, which could one day supplement and replace the lithium-ion (Li-ion) batteries used in many everyday devices today.
