Abstract
Provided are separators for use in an electrochemical cell comprising (a) an inorganic oxide and (b) an organic polymer, wherein the inorganic oxide comprises organic substituents. Also provided are electrochemical cells comprising such separators.
Claims27
A porous separator for an electrochemical cell, the separator comprising:
- (a) an inorganic oxide layer comprising aluminum boehmite;
- and
- (b) an organic polymer comprising organic polymer substituents,
- wherein the organic polymer substituents are covalently bonded to the aluminum boehmite.
