1. A battery module comprising:
a battery cell stack in which a plurality of battery cells are stacked, each battery cell of the plurality of battery cells including a portion of a battery case body extended outward as a cell terrace,
a busbar frame connected to the battery cell stack,
electrode leads protruding from the cell terraces, respectively, of the plurality of battery cells, each electrode lead having a respective distal region extending away from the battery cell stack, and
a partition wall formed on the busbar frame, the partition wall being located between the cell terrace protruding from an outermost battery cell of the plurality of battery cells in the battery cell stack and the cell terrace protruding from an inner battery cell immediately adjacent to the outermost battery cell, the partition wall being disposed between immediately adjacent ones of the electrode leads coupled to the respective outermost and inner battery cells, the distal regions of the immediately adjacent ones of the electrode leads being physically coupled with one another.
