Battery cell comprising at least one galvanic cell, battery, and method for producing a battery cell

A battery cell comprises at least one galvanic cell, a first cell housing element, and a second cell housing element. The two cell housing elements jointly substantially completely enclose the galvanic cell. The first cell housing element has inner recesses on the inner surface thereof, which inner recesses are, on an outer surface of the first cell housing element lying immediately opposite the inner surface, outer protrusions for electrically contacting a first further battery cell. First compensation elements are complementary to the inner recesses in such away and are arranged in the inner recesses in such a way that the first compensation elements, together with the inner recesses, form a substantially flat inner surface of the first cell housing element.
