Patent ID: RE44960

Claim:
A method for manufacturing a lithium polymer secondary battery, comprising steps of: mixing source materials for an electrode active material layer; coating at least one surface of a collector substrate with the mixture of the source materials in a pattern corresponding to the electrode active material layer; cutting the collector substrate with the pattern of the electrode active material layer into individual collectors; attaching an electrode terminal to an electrode lead winding a sealing tape on a portion of the electrode terminal that will be in contact with a sealing portion of a battery case; attaching an electrode terminal to an electrode lead; winding a sealing tape on a portion of the electrode terminal that will be in contact with a sealing portion of a battery case; pre-attaching an insulating member to the electrode lead extending from each of the collectors; thermally fusing the insulating member to the electrode lead; and completing formation of an electrode plate including the collector which has the electrode active material layer and the electrode lead which extends from the collector and to which the insulating member is fused.
