Abstract
(EN)
A battery module according to one embodiment of the present invention comprises: a first battery cell and a second battery cell, each of which includes an anode lead and a cathode lead, and which are interconnected in series; a short circuit induction member of which one side in a lengthwise direction is disposed between and in contact with the cathode lead of the first battery cell and the anode lead of the second battery cell, and the other side in the lengthwise direction is positioned between the anode lead of the first battery cell and the cathode lead of the second battery cell, wherein when a potential difference between the cathode lead of the first battery cell and the anode lead of the second battery cell reaches a reference value or higher, an end portion of the other side of the short circuit induction member in the lengthwise direction undergoes a bending transformation towards the cathode lead of the second battery cell so as to come in contact with the cathode lead of the second battery cell.
