Australian battery materials firm Altech Chemicals has released test results that show high purity (99.99%) 4N alumina prevents sodium leaching when used on a lithium-ion battery separator.

Test work by Germany’s Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) showed high purity alumina (HPA) could prevent battery failure modes including thermal runaway, lithium plating on the anode and life cycle reduction.
