ABSTRACT:
This invention pertains to electrochemical cells, and anode cans used therein, wherein edge regions of respective anode cans are toed-in. The anode can includes a top wall, and a first side wall depending downwardly from the top wall. The first side wall has an edge region remote from the top wall. The cathode can has a bottom wall, and a second side wall extending upwardly from the bottom wall. The edge region of the first side wall is displaced inwardly of the outer surface of the first side wall as defined at locations away from the edge region. Thus, the edge region is toed-in. Generally, the first side wall follows a path from an intermediate element of the first side wall to a distal edge of the first side wall, wherein no element of the path is directed toward the top wall. The invention further comprehends methods of making the above metal anode cans, and cells.
