Abstract

A method of producing a prismatic battery cell includes forming an initial arrangement by spatially arranging one or two wiring boards, a cathode layer, an anode layer, and at least two separator layers so as to be in parallel with each other and with respect to a winding axis. The initial arrangement is wound about the winding axis to form a battery winding. The battery winding is inserted in a cell housing, and a respective current connector is connected to each of the cathode layer and anode layer. The cell housing is filled with a liquid electrolyte, and is closed. A prismatic battery cell of this type can be included in a battery, such as a battery included with an automotive vehicle.
