Abstract
Disclosed are a busbar for cooling battery cells and a battery module using the same. The busbar for cooling battery cells is a busbar configured to cool a plurality of battery cells included in a battery module, and includes: a body portion formed in a strap shape and contacting an electrode lead of each battery cell; and a bent portion integrally formed with the body portion and extending from one end of the body portion to be bent in a thickness direction of the body portion, wherein the bent portion includes: a coupling groove coupled to a coupling protrusion that is prepared on a cooling plate of the battery module or a coupling protrusion that is prepared on a predetermined frame of the battery module, the predetermined frame supporting the busbar; and a thermal contact surface thermally contacting the cooling plate. Therefore, the busbar efficiently cools the electrode lead of each battery cell, which emits a large amount of heat, and allows simplification and size reduction of a structure of the battery module and reduction in manufacturing costs of the battery module.
