Abstract (en)
[origin: WO2016012568A1] The invention relates to a method for producing a prismatic battery cell (10), said prismatic battery cell (10) comprising a cathode layer, an anode layer and two separator layers. The method comprises the following steps: winding an initial arrangement comprising the cathode layer, the anode layer and the two separator layers around a winding axis to produce a battery winding (12), the cathode layer and the anode layer each having longitudinal sides and transverse sides and being wound with the transverse sides parallel to the winding axis, inserting the battery winding (12) in a cell housing, contacting contact surfaces (36, 38) of the cathode layer and the anode layer with current collectors (42, 44), filling the cell housing with a liquid electrolyte and closing the cell housing. The cathode layer and the anode layer, on one of their longitudinal sides, are cut to size during their supply to the initial arrangement to form contact surfaces (36, 38). The invention further relates to a prismatic battery cell (10) and to a vehicle having a battery which comprises said prismatic battery cell (10).
