Abstract
Provided is a method for welding an electrode assembly comprising stacking a plurality of electrodes to manufacture the electrode assembly, attaching a buffer tab to a surface of an outermost electrode tab of the electrode assembly, and welding a lead such that a plurality of electrode tabs and the lead are in contact with each other to dispose the buffer tab therebetween. The electrode assembly comprises the stacked plurality of electrodes comprising the lead welded to the plurality of electrode tabs, and each electrode tab of the plurality of electrode tabs protrudes in one direction from the plurality of electrodes. The buffer tab may be attached, before the welding, to the surface of the outermost electrode tab to minimize or prevent damage to the electrode tab due to pressure applied by a welding rod.
