A battery system includes neighboring first and second groups of battery cells. The battery system also includes a battery system enclosure configured to house each of the first and second groups of battery cells. The battery system additionally includes a vent channel mounted to the battery system enclosure. The vent channel is configured to expel high-temperature gases to external environment separately from each battery cell of the first group of battery cells and divert the high-temperature gases away from other battery cells of the first group of battery cells and from the second group of battery cells. The vent channel minimizes transfer of the high-temperature gases between the battery cells of the first group and from the first group of battery cells to the second group of battery cells and thereby mitigates propagation of a thermal runaway event in the battery system.
