Abstract
A zinc/air button cell, wherein the cell has a single casing, namely, the anode can. A substantially flat metal support disk is employed, to close the open end of the anode can, thus eliminating the need for the conventional cathode can. The metal support disk is locked in place within the open end of the anode can with insulating sealing material therebetween. The sealing material abuts a greater portion of the inside surface of the anode can than the outside surface of said can. A layer of cathode material comprising a manganese oxide, underlies the metal support disk. The cathode is locked in place against the metal support disk. The open end of the anode can is crimped axially and radially over the metal support disk with insulating sealing material therebetween. A tight seal results and the cell capacity is increased, since the cathode can has been eliminated.
