Spacer for prismatic battery cell, prismatic battery with the spacer and method for making a prismatic battery

摘要

The invention relates to a spacer 1 for electrically insulating a prismatic battery cell with respect to a further prismatic battery cell or another component, with a first spacer frame 3 having a lower and upper edge and a predetermined height for enclosing the narrow sides of the prismatic battery cell and one for completely covering a Broad side of the prismatic battery cell partition wall 2 provided with a first and second surface, wherein the lower edge of the spacer frame 3 is materially connected to the first surface of the partition wall 2. According to the invention, the dividing wall 2 is formed from an electrically insulating plastic film with a thickness of 0.2 mm to 0.8 mm. The present invention also relates to a prismatic battery with the spacer 1 according to the invention and to a method for producing a prismatic battery.
