Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery module including two or more battery cells and electrode tabs extended from the respective battery cells and welded to each other by laser, wherein the battery module is formed so that the electrode tabs upwardly extended are bent to include welding parts having welding surfaces in a direction perpendicular to the battery cells, wherein the battery module has swelling partitions guiding a swelling position of the battery cells and formed to enclose the battery cells at a predetermined lower region of the battery cells. 2. The battery module of claim 1 , wherein the electrode tabs are welded by a lap welding scheme in which the welding parts of the electrode tab of an anode and the electrode tab of a cathode neighboring to each other are welded in a state in which they are lapped. 3. The battery module of claim 1 , wherein the electrode tabs are welded by a butt welding scheme in which end portions of the welding parts of the electrode tab of an anode and the electrode tab of a cathode neighboring to each other are welded in a state in which they contact. 4. The battery module of claim 1 , wherein the welding parts are welded using a top-hat-type laser beam or a Gaussian-type laser beam. 5. The battery module of claim 1 , wherein the welding parts are welded using a spot laser welding.
