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.
Claims13
A battery comprising:
- an anode comprising zinc;
- a cathode comprising silver;
- and
- a separator between the anode and the cathode;
- wherein the separator comprises a porous membrane permeated with a copolymer of a divinylbenzene and a monomer having the formula:
- wherein R is an n-alkylene group;
- and
- wherein n is a non-negative integer.
A method comprising:
- permeating a porous membrane with a divinylbenzene and a monomer having the formula:
- wherein R is an n-alkylene group;
- copolymerizing the divinylbenzene and the monomer to form an amine copolymer;
- reacting the amine copolymer with a sulfonate compound having the formula CH3—SO2—O—(CH2)n—(O—SO2)m—CH3 to form a quaternary amine copolymer;
- wherein m is zero or one;
- and
- wherein n is a non-negative integer when m is zero and a positive integer when m is one;
- and
- reacting the quaternary amine copolymer with NaOH to form a copolymer of the divinylbenzene and
