Abstract
A secondary battery module comprises a casing in which vents are formed so as to allow outside air to flow in a vertical direction and one or more partition walls partition an internal space of the casing into a plurality of cell chambers. The partition wall comprises the pipe member as communication path to communicate between the cell chambers and the outside of the casing so as to allow outside air to be introduced into the internal space of the cell chambers. The secondary battery module further comprises a plurality of rod-shaped battery cells housed in the cell chambers and beams to support the battery cells along a horizontal direction and at predetermined intervals in the vertical direction in the cell chambers such that a cell axis direction is perpendicular to the vertical direction and extends along the partition wall.
