Secondary batteries having a zinc negative electrode
First Claim
1. A battery having a positive electrode including active material and a negative electrode including zinc material and cadmium particulate matter dispersed in said zinc material, said battery being constructed with such positive electrode active material and said zinc material in quantities such that said positive electrode active material is electrochemically depleted prior to electrochemical depletion of said zinc material in discharging of said battery, whereby said cadmium particulate matter is electrochemically inactive with respect to said positive electrode active material in such battery discharging, said negative electrode including:
- an electrically conductive support, a first layer overlying said conductive support and comprised of said cadmium particulate matter and a first binder therefor and a second layer overlying said first layer and comprised of said zinc material, said cadmium particulate matter and a second binder therefor.

Abstract
Batteries having a positive electrode and a negative electrode containing zinc and cadmium matter. The cadmium matter is an additive enhancing adherence of the negative electrode for zinc electroreduced from solid zinc compound state or deposited thereon from electrolytes. The zinc matter and the active material of the positive electrode are employed in quantities such that the cadmium matter is maintained electrochemically inactive with respect to the active material of the positive electrode in battery discharging.
