SECONDARY BATTERY PACK HAVING EXCELLENT PRODUCTION PROCESS PROPERTY AND STRUCTURAL STABILITY

摘要

Disclosed herein is a secondary battery pack constructed such that an insulative mounting member is coupled to the top of a battery cell through a specific coupling structure. The secondary battery pack includes 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 the outside, the insulative mounting member being constructed in a structure in which a safety element is mounted to the top of the insulative mounting member, the insulative mounting member being in direct contact with the top of the battery cell, 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. The battery case is provided at the top thereof with at least one coupling groove, and the insulative mounting member is provided with at least one through-hole communicating with the at least one coupling groove, whereby the coupling of the insulative mounting member to the battery cell is accomplished by the insertion of at least one coupling member into the at least one coupling groove through the at least one through-hole such that the at least one coupling member is not exposed to the outside of the insulative cap.
