Provided is a battery module comprising two or more battery cells which are arranged to be stacked on top of each other and can be charged/discharged, and cartridges which form a battery cell lamination structure by respectively fixing the battery cells. Each of the cartridges includes a cooling fin which is interposed between the battery cells, and a cartridge frame to fix the cooling fin. The cooling fin has two stacked cooling plates, and the two cooling plates are bent so that at least one of the ends thereof are mutually combined in a state of being spaced apart from each other to form a refrigerant passage. Also, an opening which communicates with the refrigerant passage of the cooling plates is bored on the cartridge frame. A space defined by the cartridge frame and the battery cell is spaced apart from the refrigerant passage. |
