Abstract:
1. A battery assembly comprising: a battery cell having an electrode assembly and a cap assembly wherein the cap assembly includes a cap plate that defines a first surface; a protection circuit module having a circuit board which defines a first and a second surface with a side surface interposed there between and at least one protection device mounted on the circuit board; wherein the protection circuit module is mounted on the battery cell so that the first surface of the circuit board of the protection circuit module faces the first surface of the cap plate and wherein the protection circuit module includes at least one external terminal formed on the first surface of the circuit board; at least one wire that is comprised of a continuous wire segment that extends away from the battery assembly that is coupled to the at least one external terminal of the protection circuit module so that at least a portion of the at least one wire is positioned interposed between the first surface of the circuit board and the first surface of the cap plate and so that the wire extends downward towards the cap plate in a first direction and then outward in a second direction away from the position interposed between the first surfaces of the circuit board and the cap plate and then extends outward in a third direction away from first surface of the cap plate wherein the first and third directions comprise substantially opposite directions wherein the circuit board of the protection circuit module defines an outer edge of the side surface and wherein a recess is formed in the outer edge so that the at least one wire is positioned next to the side surface of the circuit board within the recess.
