Abstract

A battery pack includes a battery, an outer enclosure housing the battery to form a battery pack, and an expandable portion extending from the outer enclosure and allowing the battery pack to expand along an X-axis of the battery pack. The expandable portion includes an inner portion, an outer portion, and a gap portion between the inner portion and the outer portion. The inner portion and the outer portion have a sealing layer to seal off an interior space and the gap portion is devoid of the sealing layer. The sealing layer allows for fluid communication between the gap portion and the interior space when a pressure exerted on the sealing layer exceeds a pressure threshold. The expandable portion includes folds allowing the expandable portion to fold toward the battery pack in an initial folded configuration and expand away from the battery pack in an at least partially unfolded configuration.
