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.

Abstract: The invention provides a zinc battery anode, comprising a substantially planar skeletal frame including conductive metal and having a portion of its surface area formed as open spaces, and further comprising an active zinc anode component encompassing the skeletal frame, the active anode component being formed of a slurry of porous granules comprising zinc, impregnated with and suspended in an electrolyte, and compacted under pressure to the skeletal frame.
