Abstract
This invention pertains to an anode current collector for alkaline electrochemical cells having zinc anodes. An anode current collector made from silicon bronze alloy has improved welding characteristics and has a minimal effect on gassing.
Claims8
An electrochemical cell comprised of an anode comprised of zinc;
- a cathode;
- and alkaline electrolyte;
- and a current collector comprised of a silicon bronze alloy that is comprised of 85-98% by weight copper and 1-5% by weight silicon with the remainder being comprised of at least one of manganese, iron, zinc, aluminum, tin, lead, or mixtures thereof;
- and a strip of metal tab stock welded to said current collector, said tab stock being a metal other than silicon bronze alloy.
