Abstract: Disclosed is a battery module, which includes a cell stack including a plurality of battery cells; a compression member disposed on at least one side of the cell stack and interposed in a gap between the battery cells, the compression member being configured to be shape-deformable by an external pressure; and a pressurizing member configured to pressurize the compression member on the at least one side of the cell stack.

Abstract: One aspect of the present disclosure includes a battery module including a battery cell stack in which battery cells having electrode leads protruding in either a first direction or a second direction are stacked, a busbar frame located on one side of the battery cell stack, a busbar and a sensing member mounted on the busbar frame, and a metal wire that connects the busbar and the sensing member, wherein the busbar includes a first metal layer located on a surface facing the busbar frame, and a second metal layer located on a surface opposite to the surface that faces the busbar frame, wherein an electrode lead passes through a slit formed in the busbar frame, and the electrode lead is bent and joined to the second metal layer, and wherein one region of the metal wire is connected to the first metal layer.
