Solid-State Electrolyte Material for Sodium-Ion Batteries

Invention SummaryWe’ve created a sodium-rich antiperovskite (NaRAP) material that greatly improves battery capabilities. Antiperovskite is a type of crystal structure that exists naturally deep in the earth’s mantle that we now can create in the lab. When used as an electrolyte (the material between positive and negative electrodes on a...
