Abstract
A cylindrical battery cell assembly which includes a plurality of cylindrical battery cells arranged so that the cylindrical battery cells having the same polarity face in the same direction, a cell holder configured to confine the cylindrical battery cells as a bundle unit, a first electrode connection member located at an upper portion of the cell holder and a second electrode connection member located at the bottom ends of the cylindrical battery cells. The second electrode connection member includes a second connection portion located at a lower portion of the cell holder and disposed to contact the second electrode terminals. A rod-shaped second terminal portion extends vertically from the second connection portion through an empty space formed inside the cell holder so that one end of the rod-shaped second terminal portion is disposed above the cell holder.
