1. A battery module comprising:
a battery cell stack in which a plurality of battery cells are stacked,
a busbar frame that is connected to the battery cell stack,
a first L-shaped frame accommodating the battery cell stack, the first L-shaped frame defining an open upper part and one open side surface, and
a second L-shaped frame accommodating the battery cell stack, the second L-shaped frame defining an open lower part and one open side surface,
wherein the first L-shaped frame and the second L-shaped frame are engaged with each other to surround four surfaces of the battery cell stack, a lower surface of the first L-shaped frame includes a first part and a second part, the first part is located at an end with respect to a length direction of the battery cell, the second part is located between the first part and a second end opposite the first end, and wherein a thickness of the first part is smaller than the thickness of the second part,
wherein the busbar frame comprises a main frame disposed perpendicular to a direction in which electrode leads of the battery cells protrude, and a bending part extending from a lower part of the main frame, and
wherein the bending part is disposed on the first part of the lower surface of the first L-shaped frame.
