Abstract:
1. A battery pack comprising: one or more bare cells; a protection circuit module provided with a circuit portion and disposed parallel to a length direction of at least one of the bare cells wherein the protection circuit module defines at least one hole extending therethrough; and a connection tab formed of a first material provided with at least one coupling member so as to electrically connect the protection circuit module to the bare cells, the at least one coupling member being integrally coupled to a connection end portion of the connection tab to form a coupling joint linking the coupling member to the connection tab and is connected to the protection circuit module wherein the connection tab is formed of a first material and extends into the at least one hole from a first side to a second side and wherein the at least one coupling member is formed of a second material that is heat deformable that couples to the second side of the protection circuit module as a result of heat deformation, the second material being a different material from the first material.
