ABSTRACT:
A case for enclosing a metal anode, air cathode, and electrolyte of a metal/air electrochemical cell is prepared by securing a multi-functional metallic cover, which has means for providing ingress of oxygen to the air cathode, to a non-conductive container. The container is capable of expanding to accomodate the growth of anodic material during discharge, while the cover is capable of supporting the air cathode against distortion on discharge and serving as the positive terminal of the cell. Metal/air cells and batteries constructed with such a case are also described.
