A battery module includes a power assembly including a first battery cell and a second battery cell in a stacked orientation relative to each other. The first battery cell includes a first tab electrode extending therefrom, and the second battery cell includes a second tab electrode extending therefrom. The battery module also includes an interconnect assembly configured to facilitate electrically coupling the first tab electrode with the second tab electrode. The interconnect assembly includes a roller housing structure about which the first and second tab electrodes at least partially conform such that the first and second tab electrodes are positioned in an opening defined by the roller housing structure. The interconnect assembly also includes a roller disposed in the opening of the roller housing structure such that the first and second tab electrodes are secured in electrical communication.
