Patent ID: 8668996

Claim:
A battery pack, comprising: a bare cell comprising a cap plate and an electrode terminal positioned on a center region of the cap plate; an insulating layer positioned over the cap plate, wherein the insulating layer comprises a first terminal hole formed on a region corresponding to the electrode terminal; and a protective circuit module positioned over the insulating layer, wherein the protective circuit module comprises a protective circuit board having a second terminal hole formed in a region corresponding to the electrode terminal wherein the protective circuit module is positioned on the insulating layer and the area of the protection circuit module and the insulating layer correspond to each other and wherein the insulating layer contacts the cap plate and the protective circuit board is positioned on the insulating layer so as to directly contact the insulating layer at the location of the cap plate so that the protective circuit board overlies the cap plate and the insulating layer is continuously interposed between the protective circuit module and the cap plate.
