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 and a first electrode terminal and a second electrode terminal formed at an upper end of the battery case; a protection circuit module (PCM) assembly including a PCM and a first connection member coupled to a bottom of the PCM, the PCM assembly being provided in one side thereof with a through-hole for coupling with an insulative mounting member; the insulative mounting member being configured such that the PCM assembly is loaded on the top of the insulative mounting member, the insulative mounting member having a second connection member coupled to the second electrode terminal of the battery cell, the second connection member being embedded in the insulative mounting member with a top and bottom of the second connection member being exposed to the outside, the insulative mounting member having a coupling member formed at a position corresponding to the through-hole, the insulative mounting member being mounted at a top of the battery cell; and an insulative cap coupled to an upper end of the battery cell to cover the insulative mounting member when the PCM assembly is loaded on the insulative mounting member, wherein the second connection member is coupled to the second electrode terminal of the battery cell by welding such that the second connection member is electrically connected to the second electrode terminal of the battery cell when the insulative mounting member is mounted on the battery cell, wherein the first connection member protrudes from one end of the PCM assembly in a lateral direction such that a region of the first connection member electrically connected to the battery cell is exposed upward from the PCM assembly, whereby the first connection member is coupled to the first electrode terminal of the battery cell upward from the PCM such that the first connection member is electrically connected to the first electrode terminal of the battery cell, in a state in which the PCM assembly is loaded on the insulative mounting member by the insertion of the coupling member into the through-hole, and wherein the electrical connection between the PCM assembly and the second connection member is provided by physical contact.
