ABSTRACT:
This invention pertains to rechargeable zinc alkaline electrochemical cells. In cells of the invention, the anode current collector comprises copper, and from about 0.5% by weight to about 11% silicon. Preferred compositions for the anode current collector comprise from about 1% by weight silicon to about 6% by weight silicon. Cells embodying anode current collectors of the invention exhibit reduced current flow under anode polarization in alkaline conditions, and reduced cell expansion under abusive electrical drain conditions. The cells are less susceptible to oxidation of the anode current collector, which is typically irreversible, than known brass anode current collectors. In general, cells of the invention are less susceptible to, and generally do not exhibit as much, irreversible chemical reaction activity, as conventional current collectors, especially oxidation of copper at the anode current collector.
