Abstract:
1. A secondary battery, comprising: a bare cell having an upper surface that is substantially planar wherein the upper surface has first and second ends in a lengthwise direction and first and second sides in a widthwise direction, wherein the lengthwise direction is greater than the widthwise direction; a protection circuit module including a circuit board that is substantially planar and extends in a plane that is substantially parallel to the plane of the upper surface of the bare cell and has a first length and width and a supporting member to combine the circuit board with the bare cell wherein the supporting member has a portion that extends in a first direction from the protection circuit module to the bare cell that is perpendicular to the plane of the upper surface of the bare cell and wherein the supporting part has a width that is smaller than the first width of the protection circuit module; and a top case covering the circuit board of the protection circuit module wherein the top case includes a side wall that extends in the first direction when the top case is covering the protection circuit module and a top surface that extends in a second direction that intersects the first direction, where the portion of the supporting member of the protection circuit module that extends in the first direction is provided with a first coupling part and the top case is provided with a second coupling part that is formed on the side wall that is integrally part of the top case combined with the first coupling part and wherein the first or second coupling part extend in a the second direction that intersects the first direction wherein the second direction is substantially parallel to the lengthwise direction of the upper surface of the bare cell, wherein the second coupling part comprise a protrusion that extends into an opening of the first coupling part.
