1. A battery pack comprising:
a bare cell comprising a first surface having a length and a width, a second surface that comprises a positive electrode and a third surface wherein a negative electrode is attached to the third surface and a fourth surface, wherein the second and third surfaces are substantially perpendicular to the first and fourth surfaces and wherein two flat surfaces interconnect the first, second, third and fourth surfaces; a protective circuit module disposed over the first surface and comprising a positive electrode connection terminal and a negative electrode connection terminal; a first lead plate disposed over the first surface and coupled to the positive electrode and the positive electrode connection terminal, wherein the first lead plate comprises a protective circuit module connector extending from one end of the first lead plate to couple to the positive electrode connection terminal; and a second lead plate disposed over the first surface and coupled to the negative electrode and the negative electrode connection terminal, wherein the second lead plate comprises a protective circuit module connector extending from one end of the second lead plate to couple to the negative electrode connection terminal; and a protective circuit element interposed between the bare cell and the protective circuit module, wherein the protective circuit element has a maximum thickness that is substantially the same as a height of the protective circuit module connectors of the first and second lead plates, such that the protective circuit element supports the protective circuit module including the protective circuit board and wherein only the protective circuit element is interposed between the bare cell and the protective circuit module; wherein the first surface of the bare cell is curved across the width of the first surface, wherein the first lead plate has a first curvature piece conforming to the first surface, wherein the second lead plate has a second curvature piece conforming to the first surface, and wherein the first curvature piece and the second curvature piece are seated on the first surface, wherein the first curvature piece and second curvature piece extend along the length of the first surface a distance greater than the curved width of the curved surface so as to provide support to the protective circuit module; and a cover that is positioned over the curved surfaces of the bare cell so as to receive the curved surfaces therein. |
