Method for Treating Electrode Tabs of Crude Cell for Lithium Secondary Battery, and Crude Cell and Lithium Secondary Battery According to the Method
First Claim
1. A method of treating electrode tabs of a crude cell for a lithium secondary battery including the steps of:
- (a) gathering a plurality of anode grids and a plurality of cathode grids of said crude cell provided with a plurality of anode plates having respective said anode grids, a plurality of cathode plates having respective said cathode grids, and a separator strip interposed between said anode plates and said cathode plates which are disposed alternately;
(b) welding an anode tab and a cathode tab to respective end portions of said anode grids and said cathode grids to form an anode side welded portion and a cathode side welded portion; and
(c) attaching an insulating tape to said anode side welded portion and said cathode side welded portion with an adhesive so that said insulating tape wraps around said welded portions.
