Abstract
A high amp-hour aluminium battery comprises a cathode, an alkaline electrolyte and at least one massive aluminium anode plate. The electrolyte contains dissolved indium. The anode is an alloy of aluminium with manganese and with one or both of magnesium and calcium and optionally gallium. When operated at a current density below 400 mA/cm.sup.2 particularly in the presence of seed crystals, the battery remains viable during and after aluminium hydroxide precipitation in the electrolyte.
