Abstract:
1. A connection member for secondary batteries to achieve the electrical connection in a battery pack including two or more cylindrical secondary batteries in a physical contact manner, the connection member comprising a terminal connection unit for connecting the battery cells arranged in a longitudinal direction in series to each other, the terminal connection unit comprising: (a) an outer circumferential contact part configured to correspond to an external shape of an electrode terminal of a lower battery cell, the outer circumferential contact part contacting the electrode terminal of the lower battery cell at a region adjacent to an outer circumference of the electrode terminal, the outer circumferential contact part having a predetermined width; (b) upward protruding parts tapered upward from the outer circumferential contact part toward a central axis of the terminal connection unit for elastically supporting the lower battery cell; and (c) protruding coupling parts protruding from the upward protruding parts to a predetermined height such that the protruding coupling parts are configured to be coupled to an electrode terminal of an upper battery cell.
