A rechargeable battery assembly comprising: an electrode assembly; a can accommodating the electrode assembly; and a cap assembly that seals an opening at a top end of the can; wherein the can comprises a front surface, a rear surface, first and second mutually opposed side surfaces and a bottom surface; the bottom surface being located intermediate the front and rear surfaces and at an opposite end of the can to the cap assembly, and the first and second side surfaces being located intermediate the front and rear surfaces and intermediate the bottom surface and the cap assembly; characterised in that the front surface comprises a first fracture portion and the rear surface comprises a second fracture portion, the said first and second fracture portions being adapted to cause separation of at least one of the cap assembly and the bottom surface from the front and rear surfaces upon the application of a compressive force in a direction extending between the first and second side surfaces. |
