Abstract
The invention relates to a battery cell (2), comprising a negative terminal (15), a positive terminal (16) and a fast discharging device (70), whereat the fast discharging device (70) comprises a first busbar (71) that is electrically connected to the negative terminal (15), a second busbar (72) that is electrically connected to the positive terminal (16) and an activation unit (75) that is connected to the first busbar (71) and to the second busbar (72). At least one connection element (91, 92) is arranged between at least one busbar (71, 72) and at least one terminal (15, 16), whereat the connection element (91, 92) is electrically conductive and a melting temperature of the connection element (91, 92) is lower than a melting temperature of the busbar (71, 72) and lower than a melting temperature of the terminal (15, 16). The invention also relates to a method for producing a corresponding battery cell (2).
