Single-ion electrolytes for solid-state alkaline batteries

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
