A battery module having excellent cooling efficiency and allowing easy recycling of inner components at disposal applies a heat-shrinkable tube serving as a module housing and a heatsink to the battery module. The battery module includes a cell assembly including a plurality of pouch-type secondary batteries having electrode leads formed to protrude in a front and rear direction and stacked on each other in a left and right direction; a heatsink located to contact an outer surface of the cell assembly and having a coolant flow path for allowing a coolant to move therein; and a heat-shrinkable tube having a tubular shape with a hollow structure in which the cell assembly and the heatsink are located, the heat-shrinkable tube being thermally shrunken so that the cell assembly and the heatsink are in contact with each other.

A power source device includes: a plurality of battery cells each including exterior can formed in a rectangular shape and including opposing main surfaces; insulating heat-shrinkable films covering the plurality of battery cells, respectively; a plurality of separators interposed between the plurality of battery cells; a battery stack formed by stacking the plurality of battery cells with separators interposed therebetween; a pair of end plates disposed on both end surfaces of the battery stack; and a plurality of bind bars disposed on each of opposing side surfaces of the battery stack and fastening the end plates to each other, wherein heat-shrinkable films have expandability in which a maximum expansion amount in a heat-shrunk state is larger than a maximum expansion amount of main surfaces of exterior can at the time of expansion of battery cells.

A battery arrangement has at least two battery modules each having a battery module housing. Each battery module housing has at least two chambers separated from one another by a dividing wall, in which chambers in each case at least one cell stack is disposed. The cell stack has at least two stacked battery cells and at least one compression pad. A thermal insulation layer is provided in each case between the dividing wall and the adjacent battery cells. The distance between the dividing wall and a battery cell adjacent to the dividing wall of a predefined first cell stack is at least twice as great as the distance between two adjacent battery cells within the predefined first cell stack.
