Abstract

There is disclosed herein a cylindrical secondary cell (1) and methods for manufacturing the cylindrical secondary cell. The cylindrical secondary cell comprises a cylindrical can (2) having a beading groove (3) formed in a wall of the cylindrical can (2) and arranged around the circumference of the cylindrical can (2), and a first conductive sheet (4), with first electrode coating (4a), wound to form a jelly roll (5) which is arranged in the cylindrical can (2), and wherein the first conductive sheet (4) comprises a portion free of first electrode coating (4a) which protrudes on a first end side (5a) of the jelly roll (5). The cylindrical secondary cell further comprises a current collector disc (6) which is electrically conductive and arranged at the first end side (5a) of the jelly roll (5) and in direct contact with at least part of the portion free of first electrode coating (4a) of the first conductive sheet (4), wherein the current collector disc (6) abuts the apex of the beading groove.
