Abstract
The invention provides a metal-air electrochemical cell, having a leak-proof, metal prismatic casing comprising a pair of interfacing interengaging rectangular tray-like casing components, a first substantially rectangular tray-like casing component having a first major surface and contiguous side walls for encompassing a cathode of the cell and a second inverted substantially tray-like casing component having a second major surface and contiguous depending side walls for encompassing an anode of the cell, the side walls of one of the casing components being of a height to facilitate the curling and crimping of an upper portion thereof over a peripheral edge area of the major surface of the other casing component to form a leak-proof, closed prismatic casing.
