Abstract
Disclosed herein are materials for use in battery separators. They include copolymers of a divinylbenzene and one or both of the monomers below (non-linked and linked). R is an n-alkylene group, and n is a positive integer. The copolymer made be made from tertiary amine monomers that are converted to quaternary amines. One battery includes a zinc anode, a silver cathode, and a tri-layer separator. The inner layer uses the linked monomer, and the outer layers use the non-linked monomer.
Claims8
A copolymer of a divinylbenzene and a compound having the formula:
- wherein each R is an independently selected n-alkylene group;
- and
- wherein n is a positive integer.
Dependencies are inferred from the claim text.
