Abstract
A battery pack to improve assembling reliability in a battery with a cover frame. The battery pack according to the present invention includes a rechargeable battery having at least one rounded lateral side; a cover frame including a frame surrounding each of lateral sides of the rechargeable battery, wherein more than at least one groove is formed at both ends of the frame covering the rounded lateral side of the rechargeable battery. Therefore, it is possible to couple the cover frame to the rechargeable battery via the groove without deforming the cover frame. Also, the rounded battery and the rounded cover frame closing each other is an effect that assembly error of a battery to cover frame can be reduced.
