The invention relates to an energy storage cell (100) in the form of a cylindrical round cell having an outside diameter of al least 30 mm, comprising an electrode-separator composite (104) having the following sequence: anode, separator, cathode. The electrode-separator composite (104) is in the form of a hollow cylindrical winding having two terminal end faces and having a winding casing lying therebetween. The energy storage cell comprises a housing, which surrounds a hollow cylindrical interior. In the interior of the housing, the electrode-separator composite (104) in the form of a winding is oriented axially In order to delimit the interior, the housing comprises: —a first annular closure element (1010), which has an outside diameter and an inside diameter; —a second annular closure element (1020), which has an outside diameter and au inside diameter; —a first tubular housing part (1030), which has two terminal circular openings, the diameter of the first tubular housing part (1030) being matched to the outside diameter of the first annular closure element (1010) and of the second annular closure element (1020); and —a second tubular housing part (1040), which has two terminal circular openings, the diameter of the second tubular housing part (1040) being matched to the inside diameter of the first annular closure element (1010) and of the second annular closure element (1020). The strip-shaped electrodes of the electrode-separator composite are contacted by means of the longitudinal edges of the electrodes, which protrude from the terminal end faces of the hollow cylindrical winding. The energy storage cell comprises an at least partially metal contact element, which is in direct contact with one of the longitudinal edges and is connected to said longitudinal edge preferably by means of welding. The first or the second annular closure element (1010, 1020) acts as the contact element. The second tubular housing part (1040) of the housing defines a channel (1500), which is open at both ends and runs axially through the energy storage cell.
