Abstract
The present invention relates to a battery module comprising: a plurality of battery cells disposed to overlap each other in a thickness direction thereof; a battery case configured to accommodate the battery cells and having a structure of which a lower portion is opened; and a heat dissipation member comprising a cover plate coupled to the lower portion of the battery case to support the battery cell and a heat dissipation body provided on one surface of the cover plate, on which the battery cell is supported, to dissipate heat generated in the battery cell, wherein the heat dissipation body comprises a first heat transfer material provided to be connected to a center of one surface of the cover plate in a longitudinal direction of the battery cell and a second heat transfer material provided on both portions of the first heat transfer material and having a structure aligned in a plurality of rows in the longitudinal direction of the battery cell, and the second heat transfer materials are aligned so that an interval therebetween is gradually narrowed from a center toward both ends of the battery cell to gradually improve heat dissipation performance from the center toward both the ends of the battery cell.
