PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

At the Spring 2015 Materials Research Conference in San Francisco earlier this month, PATHION presented two new derivative superionic solid-state electrolytes built upon LiRAP (Lithium-Rich Anti-Perovskite). PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery.
