发明名称 Toed-in anode can and electrochemical cell made therewith
摘要 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 first side wall comprises a curl at the edge region. The edge region comprises a first portion of the first outer surface on the curl. The first portion of the first outer surface is displaced from a first downward projection of the first outer surface of the first side wall as defined at a maximum perimeter element of the intermediate 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 bottom edge of the first side wall, and a reverse curl extending from the bottom edge toward the top wall. The cathode can has a bottom wall, and a second side wall extending upwardly from the bottom wall. A seal is disposed between the anode can and the cathode can.
