1. A battery module comprising: a) a plurality of battery cells spaced apart from each other by a predetermined interval and stacked in parallel with each other; b) a plurality of heat exchange members including a pair of external partition walls positioned at the outermost sides of the stacked battery cells in a direction in which the battery cells are stacked; c) internal partition walls which are slid between the stacked battery cells; d) connecting parts connecting external partition walls and internal partition walls that are adjacent to one another and connecting parts connecting internal partition walls with other internal partition walls that are adjacent to one another; e) wherein each internal partition wall is divided into a first partition wall positioned at an upper side of the battery cells and a second partition wall positioned at a lower side of the battery cells and separate from the first partition wall; f) wherein the connecting parts comprise; g) a filler applied onto the heat exchange members; h) a heat exchange pipe seated in each of the connecting parts and having a heat exchange medium circulated therein; i) wherein the first and second internal connecting parts are shifted from one another in the direction in which the battery cells are stacked so a first internal connecting part and a second internal connecting part do not connect the same pair of partition walls; j) wherein each of the heat exchange members is a heat pipe formed as a flat panel;, and k) wherein the heat exchange pipes are arranged separately from each other.
