摘要： Disclosed herein is a secondary battery pack including a battery cell having an electrode assembly mounted in a battery case together with an electrolyte, a protection circuit module (PCM) having a protection circuit for controlling overcharge, overdischarge, and overcurrent of the battery cell, an insulative mounting member mounted to a top cap of the battery cell, and an insulative cap coupled to the upper end of the battery cell, wherein the top cap is provided with at least one protrusion-type electrode terminal, and the top cap is provided at a partial region where the protrusion-type electrode terminal is not formed with a space (depression space) depressed downward by a predetermined depth. The insulative mounting member is provided with a through-hole (a first through-hole) corresponding to the protrusion-type electrode terminal and a through-hole (a second through-hole) corresponding to the depression space, the PCM is provided with a coupling through-hole corresponding to the first through-hole, and the coupling of the insulative mounting member and the PCM to the battery cell is achieved by successively fixedly inserting the protrusion-type electrode terminal through the first through-hole of the insulative mounting member and the coupling through-hole of the PCM.
