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.
