Abstract
A battery module includes a plurality of secondary batteries, each including an electrode assembly and an electrolyte accommodated in an inner space of an exterior case. The battery module also includes an electrode lead having a body and a plate-shaped head portion. A first end of the body is electrically connected to a positive electrode plate or a negative electrode plate of the electrode assembly, and a second end of the body protrudes outward from the exterior case. The plate-shaped head extends in both directions perpendicular to the protruding direction of the body from the second end. The battery module also includes a bus bar having a plate shape with a slit extending inwardly from one end thereof so as to receive a portion of the body. The electrode lead and the bus bar may be at least partially made of an electrically conductive material.
