Abstract:
1. 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 mounting member having openings, through which electrode terminals of the battery cell are exposed to an outside, the insulative mounting member being in direct contact with the top of the battery cell; a safety element mounted to a top of the insulative mounting member; and an insulative cap coupled to the top of the battery cell such that the insulative cap surrounds the insulative mounting member while the safety element is mounted to the insulative mounting member, wherein the battery case is provided at the top thereof with at least one coupling groove, and the insulative mounting member is provided at a bottom thereof with at least one coupling protrusion corresponding to the at least one coupling groove, whereby the coupling of the insulative mounting member to the battery cell is accomplished by insertion of the coupling protrusion into the coupling groove, and wherein the insulative mounting member has a size approximately corresponding to that of the top of the battery cell, the insulative mounting member is provided at the middle thereof with a first opening, through which a first electrode terminal of the battery cell is exposed to the outside, and the insulative mounting member is provided at a position spaced a predetermined distance from the first opening with a second opening, through which a portion of the top of the battery case of the battery cell is exposed to the outside.
