Patent ID: 8574751

Claim:
A secondary battery with a protective circuit module comprising: a rechargeable bare cell having a first electrode and a second electrode; an electrode terminal protruding from the rechargeable bare cell; a protective circuit board comprising a protective circuit for the rechargeable bare cell; a conductive bonding layer on the protective circuit board; a secondary protective element assembly comprising a connecting plate bonded to the protective circuit board by the conductive bonding layer; a first lead plate electrically connecting the secondary protective element assembly to the first electrode; a second lead plate directly contacting the electrode terminal and the protective circuit board to electrically connect the protective circuit board to the second electrode; and an insulating member secured to a longitudinal side of the rechargeable bare cell, wherein the insulating member is both between a portion of the first lead plate and the rechargeable bare cell and between a portion of the second lead plate and the rechargeable bare cell, wherein the connecting plate comprises a first connecting portion in contact with the conductive bonding layer, a coupling portion extending from the first connecting portion, and a second connecting portion substantially parallel to the first connecting portion, wherein the first connecting portion comprises a plurality of through holes allowing the conductive bonding layer to penetrate therethrough and a portion of the conductive bonding layer forming a reinforcement protrusion on a side of the first connecting portion opposite the protective circuit board.
