Abstract:
1. A battery pack, comprising: a bare cell including an electrode terminal, a cap plate and a gasket insulating the electrode terminal from the cap plate, a polarity of the cap plate being different from a polarity of the electrode terminal; a protection circuit board including a first aperture in a region corresponding to the electrode terminal, the first aperture penetrating the protection circuit board; a first lead terminal electrically connected between the electrode terminal of the bare cell and the protection circuit board, the first lead terminal disposing on the electrode terminal of the bare cell; and a second lead terminal electrically connected between the cap plate of the bare cell and the protection circuit board, wherein the first lead terminal and the second lead terminal are connected to a first side of the protection circuit board, wherein the first lead terminal having a rectangular prism shape with six surfaces, at least four of the six surfaces are completely embedded into and in direct contact with the protection circuit board with only a portion of a fifth surface of the six surfaces of the first lead terminal being exposed to the first aperture and another portion of the fifth surface is in direct contact with the protection circuit board, a portion of a sixth surface of the six surfaces in direct contact with the electrode terminal and another portion of the sixth portion not in contact with any structure.
