Claim 13:
14. A method for assembling a secondary cell comprising an electrode assembly accommodated in a casing, wherein the casing comprises a body, a first end plate arranged at a first open end of the body and a second end plate arranged at a second open end of the body, wherein the first and second open ends are arranged at opposite sides of the body with respect to a length direction of the body, the method comprising:
inserting the electrode assembly into the body via the second open end;
attaching a contacting tab to a first tab of an anode electrode of the of the electrode assembly and to a first current collector, electrically connected to a first terminal of the first end plate to provide electrical contact between the anode electrode and the first terminal;
arranging a first spacer arrangement, comprising a first and a second spacer element, between the first end plate and the electrode assembly and on opposite sides of the contacting tab, thereby securing the electrode assembly in the length direction of the body;
attaching a second current collector to a second tab of a cathode electrode of the electrode assembly and to the second end plate to provide electrical contact between the cathode electrode and a second terminal of the second end plate and to secure the electrode assembly in a plane orthogonal to the length direction of the body;
arranging a second spacer arrangement between the second end plate and the electrode assembly to secure the electrode assembly in the length direction of the body;
arranging the contacting tab such that it protrudes from the first open end of the body; and
attaching the contacting tab to the first current collector of the first end plate while the first end plate is oriented substantially parallel to the length direction of the body.
