Abstract

Battery, characterized in that it comprises: a cell assembly (10) wherein the cell assembly (10) comprises a first terminal tab (11); a terminal pin (20); a current collector arrangement (30) wherein the terminal pin (20) is located on a first side of the current collector arrangement (30), the cell assembly (10) is located on a second side of the current collector arrangement (30), and the current collector arrangement (30) comprises a first current collector (31) and an insulating connecting element (32), wherein the first current collector (31) is fixed relative to the insulating connecting element (32);wherein the first current collector (31) comprises a projection (311) and a main body (312) which are rigidly connected, wherein the projection (311) has a projection area (3111), wherein a first end face of the projection area (3111) is configured to be rigidly and electrically connected to the pole pin (20), and the main body (312) comprises a terminal tab weld area (3121), wherein a second end face of the terminal tab weld area (3121) is configured to be rigidly and electrically connected to the first terminal tab (11), wherein the first current collector (31) is stamped in one piece, wherein by stamping or milling the thickness of the terminal tab weld area (3121) becomes less than the thickness of the projection area (3111).
