Abstract
A negative zinc electrode for use in an alkaline battery has an active material consisting of zinc-magnesium alloy containing magnesium in an amount in the range of greater than 0% to about 15% by weight. The zinc-magnesium alloy may also contain a small amount of an additive metal that reduces the hydrogen overvoltage or an effective amount of an additive metal that increases the porosity, such as from 5 to 25% aluminum by weight of the zinc. The zinc-magnesium alloy is applied in particulate form to a suitable current collector using any one of a number of conventional methods such as die-pressing, mixing with a filler or a polymer and heating, sintering or compaction. The electrode has a cycle life longer than that of a conventional zinc oxide-based electrode, and causes little or no formation of dendrites.
