OG exemplary drawing
 
1. A battery module comprising:
a cell laminate obtained by lamination of a plurality of battery cells;
a housing for accommodating the cell laminate; and
a reinforcing pole which penetrates the battery cell laminate,
wherein each of the plurality of battery cells comprises a cell body for accommodating an electrode assembly, a first electrode lead protruding in a first direction of the cell body, and a second electrode lead in a second direction opposite to the first direction,
wherein the first electrode lead forms a first dead space on a first side surface of the cell body by being closer to a top side of the cell body, and
wherein the second electrode lead forms a second dead space on a second side surface by being closer to a bottom side of the cell body,
wherein the cell laminate has m battery cells arranged in an x-axis direction, and n battery cells arranged in a y-axis direction,
wherein the m is an integer of 2 or more, wherein the n is an integer of 2 or more, and
wherein the reinforcing pole penetrates a dead space between the battery cells arranged in the x-axis direction.
