  • Publication number: 20200328387
    Abstract: The present invention relates to a battery module including an ultra-long battery cell. The battery module according to the invention includes: ultra-long battery cells each having opposite ends to which a plurality of electrode tabs are connected; a battery stack formed by stacking the battery cells; end-side bus bar assemblies formed at opposite ends of the battery stack, respectively, and electrically connecting the electrode tabs of the battery cells; transverse bus bar assemblies each electrically connecting electrode tabs connected to opposite ends of an uppermost battery cell or a lowermost battery cell in the battery stack; and a case accommodating the battery stack, the end-side bus bar assemblies, and the transverse bus barr assemblies. With the battery module according to the present invention, it is possible to suppress an increase in internal resistance of the ultra-long battery cell and heating, and to improve structural stability.
