Solid-state revolution: 100x power battery tech may soon run at room temp

Researchers at the Federal Institute for Materials Research and Testing are developing a novel NASICON-based solid electrolyte for sodium batteries. This could enable solid-state batteries 100 times more powerful than current lithium-ion ones, operating at room temperature. The team aims to replace expensive hafnium with sustainable dopants to stabilize the electrolyte. If successful, this technology could lead to safer, cheaper, and faster-charging batteries for various applications, advancing energy storage capabilities and supporting decarbonization efforts.
