Abstract
A pouch cell (20A, 20) includes a generally rectangular cell housing (20, 21) formed of a metal laminated film, an electrode assembly (60) that is sealed within the cell housing (20, 21), and a current collector device disposed in the cell housing (20, 21). The electrode assembly (60) includes positive electrode portions alternating with negative electrode portions, the positive electrode portions and the negative electrode portions being separated by at least one separator and stacked along a stack axis (66). The current collector device is electrically connected to one of the positive electrode portions and the negative electrode portions and exits the cell housing (20, 21) via an opening (28, 428) formed in the cell housing (20, 21). The opening (28, 428) is formed in a side (22, 24) wall of the cell housing (20, 21) at a location spaced apart from the sealed joint (40) that closes the cell housing (20, 21) and at a location facing the stack axis (66).
