Abstract

A ceramic-coated separator for a lithium-containing electrochemical cell and methods of preparing the ceramic-coated separator are provided. The ceramic-coated separator may be manufactured by preparing a slurry that includes one or more lithiated oxides and a binder and disposing the slurry onto one or more surfaces of a porous substrate. The slurry may be dried to from a ceramic coating on the one or more surfaces of the porous substrate so as to create the ceramic-coated separator. The ceramic coating may include one or more lithiated oxides selected from LiSiO, LiAlO, LiTiO, LiNbO, LiPO, LiCrO, and LiCrO.
