Pouch cell and electrical device

Abstract

A pouch cell characterized in that it comprises: a housing arrangement (6) forming a receiving chamber; a cell (1) arranged in the receiving chamber comprising a base body and pole vanes (3) extending from the base body;Insulating adhesive tape (2) which is adhered circumferentially along a circumferential direction of the cell (1) on an outer surface of the base body of the cell (1), wherein the insulating adhesive tape (2) comprises a first end (201) and a second end (202), wherein the first end (201), after the insulating adhesive tape (2) has circumferentially surrounded the cell (1), partially overlaps the second end (202) in an adhesive manner, wherein an area in which the first end (201) and the second end (202) overlap each other forms an overlap area (203), wherein along a width direction of the insulating adhesive tape (2) a side of the first end (201) furthest from the overlap area (203) forms a first side edge (204) and a side of the second end (202) furthest from the overlap area (203) forms a second side edge (205);wherein in the width direction of the insulating adhesive tape (2) the width of the overlap area (203) is L0 mm, the distance between the overlap area (203) and the first side edge (204) is L1 mm, the distance between the overlap area (203) and the second side edge (205) is L2 mm, and L0 / (L1+L2) is in the range of 0.8 to 37.;
