1. A battery module comprising:
at least one battery cell including two electrode leads disposed in directions opposite to each other;
a first plate disposed on a first side of the at least one battery cell to dissipate heat generated by the at least one battery cell externally; and
a second plate disposed on a second side of the at least one battery cell to dissipate heat generated by the at least one battery cell externally,
wherein the at least one battery cell comprises an accommodating portion in which an electrode assembly is accommodated and a sealing portion disposed along at least a portion of a perimeter of the accommodating portion,
wherein the accommodating portion includes a first side, a second side, and a third side on which an electrode lead among the two electrode leads is disposed,
wherein the second side of the accommodating portion, opposite to the first side of the accommodating portion, is not formed with the sealing portion,
wherein the at least one battery cell is disposed such that the second side of the accommodating portion faces the first plate,
wherein each electrode lead of the at least one battery cell is disposed between the first side and the second side and is disposed to be biased toward the second side,
wherein the sealing portion includes a first sealing portion sealing the third side of the accommodation portion and a folded second sealing portion sealing the first side of the accommodation portion, and
wherein the folded second sealing portion is disposed adjacent to the second plate than the first plate, and the second side of the accommodation portion is disposed adjacent to the first plate than the second plate.
