Claim 0:
1. A secondary cell, comprising:
an electrode assembly; and
a casing accommodating the electrode assembly;
wherein:
the casing comprises a body, a first end plate and a second end plate, wherein the first and second end plates are arranged on opposite sides of the body with respect to a length direction of the body, and wherein the first end plate comprises a first current collector electrically connected to a first terminal of the secondary cell, and wherein the second end plate comprises a second terminal of the secondary cell;
the first end plate comprises:
a contacting tab configured to provide an electrical contact between a first tab of an anode electrode of the electrode assembly and the first current collector; and
a first spacer arrangement comprising a first and a second spacer element arranged between the first end plate and the electrode assembly and on opposite sides of the contacting tab, wherein the first and second spacer elements are configured to secure the electrode assembly in the length direction of the body;

the second end plate comprises:
a second current collector arranged to provide an electrical contact between a second tab of a cathode electrode of the electrode assembly and the second terminal, wherein the second current collector is attached to the second tab of the cathode electrode to secure the electrode assembly in a plane orthogonal to the length direction of the body; and
a second spacer arrangement arranged between the second end plate and the electrode assembly and configured to secure the electrode assembly in the length direction of the body; and

the second current collector comprises a plate-shaped portion attached to an inner surface of the second end plate and at least one edge portion protruding towards the electrode assembly.
