Provided is a battery module with high cooling efficiency, which shows a high contact ratio between a coolant and a unit cell to remove a gradient in flow rate of the coolant, and is useful as a power source for electric cars and hybrid electric cars. The battery module with high cooling efficiency comprises a plurality of unit cells(200) stacked successively and a cooling system using a coolant flowing through a cavity (flow path)(500) between one unit cell and another unit cell to perform contact type cooling, wherein the flow path is inclined at a predetermined angle to the flow direction of the coolant in the inlet(510) of the flow path. The predetermined angle is 2-30 deg. |
