Leakage of electrolyte from metal/plastics joints of a sealed alkaline cell is prevented by connecting the metal to the positive electrode and by leaving exposed at least as much electrode as is in contact with the electrolyte, thus avoiding excessive gas pressures. The bulk of the electrolyte is fixed by capillary action in the pores of the electrodes and separators. Preferably nickel or nickel-plated metal spacers between the positive electrodes and the metal casing and synthetic resin separators for the negative electrodes are used. The electrode assembly may be concentric or may be formed into a spiral. Two negative half electrodes 11 spaced by a metal mesh 22 have three positives 12 spaced by separator 13 from the negative and metallic spacers 14 surround the positive, and connect them to the casing 15.
