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 includes the steps of: (a) gathering a plurality of anode grids and plurality of cathode grids having a plurality of anode plates and cathode plates, respectively; (b) welding an anode tab and a cathode tab to respective end portions of the anode grids and the cathode grids to form an anode side welded portion and cathode side welded portion; and (c) attaching an insulating tape to the anode side welded portion and cathode side welded portion with an adhesive to wrap the welded portions with an insulating tape.
