摘要： Provided is a battery module for a secondary battery. The battery module includes a busbar for a connection of electrode tabs. According to exemplary embodiments of the present disclosure, in a battery module for a secondary battery, a thickness of a welded portion may be reduced while maintaining a total cross-sectional area of a busbar when electrode tabs of each of secondary batteries are connected in series or in parallel by a laser welding. Thus, the battery module may have an enhanced welding quality, and also may have an effect of being applicable to a high-capacity battery or a battery that is used for a long period of time.
