Abstract
Provided is a battery module in which a connection structure between electrode leads is changed to prevent a heat generation phenomenon when overcharged and to allow easy connection and disconnection between secondary batteries, and a method for manufacturing the same. The battery module according to the present disclosure includes a secondary battery stack formed by stacking a plurality of secondary batteries having electrode leads, wherein each electrode lead protrudes from the corresponding secondary battery, and each electrode lead has a bent part, and the bent parts of opposite-polarity electrode leads of neighboring secondary batteries are stacked with an elastic body interposed therebetween, and the corresponding stacked part is fastened by an insulating bolt including a washer, with the elastic body being compressed.
