  • Nickel zinc battery design
    Patent number: 8703330
    Abstract: Nickel zinc cylindrical battery cell designs are described. The designs provided limit dendrite formation and prevent build up of hydrogen gas in the cell. The present invention also provides low-impedance cells required by rapid discharge applications. The cylindrical battery cells may have polarity opposite of that of conventional power cells, with a negative cap and positive can. The cylindrical cells may include a gel electrolyte reservoir.

  • Cylindrical nickel-zinc cell with negative can
    Patent number: 8048558
    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.

  • METALLIC ZINC-BASED CURRENT COLLECTOR
    Publication number: 20100092857
    Abstract: A nickel zinc battery cell includes a metallic zinc-based current collection substrate as a part of the negative electrode. The metallic zinc-based current collector may be made of or be coated with a zinc metal or zinc alloy material and may be a foil, perforated, or expanded material. Battery cells incorporating the zinc-based current collector exhibit good cycle lifetime and initial charge performance.
