Abstract
Primary electric cells are formed using as the combination anode and container for the cell aluminum base alloys containing up to 2.0% by weight zinc, up to 5.0% by weight magnesium, less than 0.1% by weight iron, elements selected from the group consisting of cadmium, tin and lead, or any combination thereof, in amounts ranging from 0.05 to 0.3% by weight of each of cadmium and tin and from 0.01 to 0.20% by weight for lead, balance aluminum. The aluminum alloys reduce the incidence of hydrogen gas evolution within the cells. The aluminum base alloys may also be utilized as anode material for uses other than primary cells.
