1. A device for disconnecting an electrical connection to a battery cell in the event of outgassing, said device comprising:
a connecting conductor electrically connecting a connection point electrically contacting a cell pole on an outgassing valve side of the battery cell to an electrical contact point;
said connecting conductor forming a fuse; and
a spacer supported between the connection point and the contact point;
wherein the spacer provides structural support that blocks movement of the cell pole so that, in the event of outgassing, the spacer retains the cell pole and the connecting point, and electrically insulates the connection point from the contact point.
