LAGP Conductive Ceramic Separator Sheets/Membrane Description
LAGP (Li1.5Al0.5Ge1.5P3O12) is an electrolyte for all-solid-state lithium batteries with high ionic conductivity of 4x10-4 S/cm. It can also be made to ceramic separator sheets to serve Li-air & solid rechargeable batteries. LAGP separator sheets can block moisture and air, protect the anode metal Li from oxidation, allowing lithium ions to freely enter and exit, and is the key material for lithium-ion air battery. Comparing to LATP, LAGP has better electrochemical stability so that LAGP is superior to LATP.
