An electrochemical cell includes an annular electrode composite body; and an annular liquid-tight housing formed as a hollow cylinder and including an annular interior space, wherein the housing is arranged around a central aperture or recess, the housing has a height of 5 mm to 40 mm and an external diameter of 6 mm to 20 mm, and the annular electrode composite body is arranged in the annular interior space.

Electrochemical cell and apparatus containing the cell

A button cell has a winding arranged in the cup-shaped, positive-polarity housing half such that one of the flat end sides points in the direction of the cup base, the circumferential outer side thereof bears against the circumferential cup wall and the outer side together with the cup wall forms a clamping zone in which the first current output conductor is clamped.
