Abstract
A method for treating electrode tabs of a crude cell for a lithium secondary battery, a crude cell for a lithium secondary battery manufactured according to the method, and a lithium secondary battery employing the crude cell are disclosed. The method for treating electrode tabs of a crude cell provided with a plurality of anode plates having respective anode grids, a plurality of anode plates having respective anode grids includes the steps of: (a) welding a tab member to an end of a grid of the crude cell to create a welded portion; and (b) attaching an insulating tape to the circumference of the electrode tab so that the insulating tape can wrap around the electrode tab, which is formed by the welded portion.
