CYLINDRICAL AIR-CELL

摘要

This invention is to improve the sealing of the top and/or bottom of cylindrical positive electrode of air-cell, and to prevent the leakage or electrolyte from the gelled zinc negative electrode disposed within the positive electrode which is constituted of a collector layer, catalyst layer, and a porous layer. By utilizing a positive electrode constituted of a metallic collector layer made of metal mesh or such, a catalyst layer disposed around said collector, and fluororesin porous layer, as an air electrode, an outer cup and an inner cup are pressed on the top of the positive electrode in order to prevent the leakage of electrolyte. The possible leakage of electrolyte from the bottom of positive electrode can be prevented by providing a resin sealing body with a ring-shaped indentation fitted to the bottom of positive electrode, and by inserting this resin sealing body into the positive electrode canister, and by pressing the side wall of positive electrode canister against the side of resin sealing body in order to fit the bottom of positive electrode to the indentation of resin sealing body.
