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.

An apparatus may store at least one object including at least one top end and at least one bottom end. The apparatus may include a container configured to store the at least one object and a pouch containing a liquid. The pouch may be configured to substantially cover the at least one top end of the at least one object when stored inside the container. The pouch may be configured to contact the at least one top end of the at least one object and to open when contacted by contents expelled from the at least one object due to thermal runaway.
