Abstract
The present invention relates to a rechargeable battery, particularly a rechargeable battery having a bare cell, a protective circuit board, a lead plate, and a flat plate attached to a cap plate of the bare cell for connecting the lead plate to the cap plate. According to the invention, the lead plate is not directly combined with the cap plate, in which the cap plate is made of material differently from the lead plate, and the lead plate and cap plate are respectively welded to the metal layer made of the same material by means of the flat plate formed of metal, thereby allowing them to be easily combined with each other and the adhesive force to be enhanced.
