1. A battery module comprising:
a plurality of battery cells stacked in a horizontal direction, wherein each of the plurality battery cells includes an upper side divided into two regions by a sealing portion formed in the upper side of the battery cell;
a first plate supporting lower sides of the plurality of the battery cells and dissipating heat generated in the battery cells; and
a second plate in contact with upper sides of the battery cells and dissipating heat generated in the battery cells,
wherein the second plate comprises accommodation grooves to receive corresponding the sealing portions,
wherein at least one of the plurality of battery cells is in contact with the second plate in both of the two regions of the upper side, and
wherein a heat transfer material having a dielectric strength of from 10 kV/mm to 30 kV/mm is disposed in the accommodation grooves.
