Abstract
A nickel-zinc battery cell is formed with a negative can, a positive cap, and a jelly roll of electrochemically active positive and negative materials within. The inner surface of the can is protected with an anticorrosive material that may be coated or plated onto the can. Good electrical contact between the jelly roll and the cap is achieved through folding the nickel substrate over to contact a positive current collection disk.
