Abstract

An improved alkaline galvanic cell which includes an anode sealing plate of a layered structure serving as an anode terminal and having a copper layer as the innermost layer, a cathode container serving as a cathode terminal, an insulating packing provided around the peripheral edge of the anode sealing plate to be fitted into the cathode container for hermetically sealing the cell, and two layers of sealing agents provided between the anode sealing plate and the insulating packing. One of the layers at the side of the anode sealing plate is of epoxy adduct polyamide amine having amine valence in the range of 50 to 400, while the other of the layers at the side of the insulating packing is arranged to be of chlorosulfonated polyethylene for improvement of resistance against leakage of electrolyte.
