ANODE DESIGN FOR A PRISMATICALLY WOUND LiMnO2 CELL

摘要

A prismatic cell (12) for implantable medical devices includes an elongated anode (11) and cathode (18) folded together to form a prismatic cell. The anode (11) includes an anode tab (22) which does not extend to the bottom edge (24) of the anode (11), with heat-resistant tape (36) on the opposite side of the anode, likewise not extending to the bottom edge (24) of the anode (11). This provides a strip (44) of anode material below the anode tab which acts as a current collector reducing the increase in impedance as the cell is discharged.
