ABSTRACT:
Disclosed is a rechargeable battery including: a bare cell composed of an electrode assembly including a negative electrode, a separator and a positive electrode, a container for housing the electrode assembly and an electrolyte, and a cap assembly for closing an opening of the container; and a safety device electrically coupled to an outer surface of the bare cell, wherein the safety device is coupled to the bare cell by being incorporated into a battery component part, and each of bonding surfaces of the bare cell and the battery component to be bonded to each other has a bonding parts capable of forming a mechanical bonding between the bare cell and the battery component. The rechargeable battery permits a safety device such as a protective circuit board and a bimetal device to be coupled to a bare cell in a stable and simple manner. Additionally, the mechanical bonding parts between the safety device and the bare cell can be separated so that the safety device such as a protective circuit board can be reused.
