Abstract
The present invention relates to a method for welding an electrode assembly in which electrode tabs and leads are welded in the electrode assembly having a plurality of stacked electrodes having electrode tabs protruding in one direction. The method is characterized by including providing the electrode assembly by stacking the electrodes to make the electrode assembly; attaching a buffer tab to a surface of the outermost electrode tab of the electrode assembly; and welding the lead in a state in which the electrode tab and the lead are in contact with each other to dispose the buffer tab between the electrode tab and the lead. In the method for welding an electrode assembly according to the present invention having the characteristics as described above, the buffer tab can be attached to the surface of the outermost electrode tab before welding to minimize or prevent damage to the electrode tab due to pressure applied by the welding rod.
