Battery pack and fabricating method thereof

Abstract

Disclosed are a battery pack and a fabricating method which can increase the coupling strength of a bare cell and a circuit accessory and prevent the circuit accessory from being separated from the bare cell due to external forces such as bending, twisting and falling of a battery, by forming a fixing member protruding from the upper part of the bare cell, and coupling the fixing member with a fixing member hole of the circuit accessory formed in advance by injection molding in the type of the fixing member being laid across the fixing member hole. The battery pack includes: a bare cell having a cap plate on the upper part of the bare cell; and a circuit accessory coupled with the upper part of the bare cell, wherein a fixing member is formed to protrude from the outer surface of the cap plate, a fixing member hole corresponding to the fixing member is formed on the circuit accessory, and the fixing member is inserted in and is coupled with the fixing member hole.
