1. A battery module comprising:
a plurality of battery cells each having a respective first electrode lead protruding along a protruding dimension from a respective first surface of the respective battery cell of the plurality of battery cells, the plurality of battery cells being stacked along a stacking dimension such that the first surfaces of the plurality of battery cells collectively define a first plane extending along the stacking dimension;
a busbar frame assembly supporting the plurality of battery cells and comprising a plurality of first busbars electrically connected to the first electrode leads of the plurality of battery cells, the busbar frame assembly including a planar frame extending along the first plane and having the plurality of first busbars positioned therealong; and
a plurality of fixing jig holes provided in top and bottom surfaces of the busbar frame assembly, and into which welding jigs for fixing the busbar frame assembly are configured to be inserted in a welding process for electrically connecting the first electrode leads of the plurality of battery cells to the plurality of busbars, the plurality of fixing jig holes each having an axial dimension along which the welding jigs are configured to be inserted, the axial dimensions of the plurality of fixing jig holes being oriented along the first plane such that the axial dimensions are perpendicular to the protruding dimensions of the first electrode leads.
