Patent ID: 8852766

Claim:
A secondary battery pack comprising: a battery cell having an electrode assembly of a cathode/separator/anode structure mounted in a battery case together with an electrolyte in a sealed state; an insulative mourning member having openings, through which electrode terminals of the battery cell are exposed to the outside, the insulative mounting member being configured to have a structure in which a safety element is mounted to the top of the insulative mounting member, the insulative mounting member being disposed in direct contact with the top of the battery cell; and an insulative cap coupled to the top of the battery cell so that the insulative cap surrounds the insulative mounting member in a state in which the safety element is mounted to the insulative mounting member, wherein the battery case is provided at the top thereof with a coupling groove, and the insulative cap is provided at the bottom thereof with a coupling protrusion formed in a shape corresponding to the coupling groove, the coupling of the insulative cap to the battery cell being achieved by the insertion of the coupling protrusion into the coupling groove.
