Abstract
The evolution of hydrogen in rechargeable silver-zinc batteries is reduced by the incorporation into the zinc electrode of a minor proportion of a lead oxide, e.g. either lead oxide (PbO) or lead dioxide (PbO.sub.2). The invention further relates in general to electrodes for batteries, said electrodes consisting mainly of zinc oxide and having a small amount of lead oxide or lead dioxide distributed therethrough.
