Embodiments include a battery module having a first battery cell, a neighboring second battery cell, and insulating members positioned on opposing sides of the first battery cell. The battery module also includes a battery module enclosure surrounded by an external environment and configured to house each of the first battery cell, the neighboring second battery cell, and the insulating members and a module cover mounted to the battery module enclosure and including a vent feature configured to expel high-temperature gases from the first battery cell into the external environment, to thereby minimize transfer of the high-temperature gases from the first battery cell to the neighboring second battery cell and control propagation of a thermal runaway event in the battery module. The insulating members include tapered portions disposed between the first battery cell and the vent feature.
