Secondary battery including protection circuit module

A secondary battery, comprising:

• a bare cell;
• a protection circuit module comprising a circuit board and two supporting members to couple the circuit board to the bare cell, the protection circuit module being coupled to the bare cell;
• and
• a top case covering the circuit board of the protection circuit module, wherein
• the top case comprises a cover plate;
• a side wall extending downward from the cover plate;
• end portions positioned at ends in the length direction of the top case;
• and coupling slots formed by carving inner walls of the end portions;
• the circuit board comprises a first surface, a second surface, and ends;
• and the ends are accommodated into the coupling slots;
• each of the supporting members comprises:
• a support extending between the circuit board of the protection circuit module and the bare cell;
• a first connector extending from the top of the support and being coupled to the circuit board of the protection circuit module;
• and
• a second connector extending from the bottom of the support and being coupled to the bare cell, wherein the support of each of the supporting members is spaced-apart from ends of the circuit board;
• and
• each of the ends of the circuit board extends further outward than corresponding supports of the supporting members, the top case further comprising accommodating slots, each of said accommodating slots to accommodate a corresponding second connector of a corresponding one of the supporting members.
