Abstract
Provided is a battery module having improved safety by disconnecting an electrical connection due to short-circuit of electrode tabs by bending the electrode tabs upwardly extended to form welding parts having welding surfaces in a direction perpendicular to the battery module, performing a spot laser welding on the welding parts in a lap welding scheme using a top-hat-type laser beam or a Gaussian-type laser beam, and including a swelling partition to adjust a swelling position when a swelling increasing a volume due to a problem in a battery cell occurs and to short-circuit the electrode tabs.
