Claim Text:
1. A method of fabricating a rechargeable battery, the method comprising: forming a protective circuit board portion having a rectangular prism shape into one single body through resin molding, said protective circuit board portion having a PTC element and a Protective Circuit Module (PCM) entirely contained within the protective circuit board portion and two electrical terminals extending from opposite sides of the protective circuit board portion; connecting the protective circuit board portion to a bare cell, the bare cell has a rectangular prism shape with four long sides of equal length and two short sides, any one of the four long sides of the bare cell are longer than any one of the two short sides of the bare cell, the protective circuit board has a same length as one of the four long sides of the bare cell, said protective circuit board portion containing the PTC and PCM is positioned exclusively along one of the four long sides of the bare cell; respectively electrically connecting the two electrical terminals of the protective circuit board portion to two electrodes of the bare cell, the two electrodes of the bare cell are located on opposite sides of the bare cell from one another on each of the short sides of the bare cell and the two electrical terminals are each bent at a 90 degree angle; and positioning an exterior material to attach the protective circuit module to the bare cell, which exposes at least one external electrode terminal portion, said exterior material is directly attached to three of the six sides of the protective circuit board portion and directly to three of the four long sides of the bare cell, wherein the exterior material is formed by taping with a thin resin.
