ABSTRACT:
Cylindrical alkaline manganese dioxide-zinc cell with improved bottom sealing, where the cell comprises a coaxial assembly of a metal can closed at the bottom, a cylindrical cathode inserted in the can up to abutment at the bottom with an insulating member, a separator system in direct contact with internal surface of the cathode, a zinc anode arranged in the hollow interior of the separator system and insulated from the can, an alkaline electrolyte. The separator system extends up to the bottom end of the cathode, and a thermoplastic sealant is provided at the bottom edge zone of the separator system extending into said zone as a bead. The sealant impregnates the separator system at said edge zone.
