Abstract
A separator for an alkali metal ion rechargeable battery includes a porous ceramic alkali ion conductive membrane which is inert to liquid alkali ion solution as well as anode and cathode materials. The porous ceramic separator is structurally self-supporting and maintains its structural integrity at high temperature. The ceramic separator may have a thickness of at least 200 μm and a porosity in the range from 20% to 70%. The separator may be in the form of a clad composite separator structure in which one or more layers of porous and inert ceramic or polymer membrane materials are clad to the alkali ion conductive membrane. The porous and inert alkali ion conductive ceramic membrane may comprise a NaSICON-type, LiSICON-type, or beta alumina material.
