Ceramatec is developing new batteries that make use of a non-porous, high ion conductivity ceramic membrane employing a lithium-sulfur (Li-S) battery chemistry. Porous separators found in today’s batteries contain liquids that negatively impact cycle life. To address this, Ceramatec’s battery includes a ceramic membrane to help to hold charge while not in use. This new design would also provide load bearing capability, improved mechanical integrity, and extend battery life. Ceramatec will build and demonstrate its innovative, low-cost, non-porous membrane in a prototype Li-S battery with a smaller size and higher storage capacity than conventional batteries. The project progress will be updated.
