A battery system includes a first battery cell and a neighboring second battery cell. The battery system also includes a battery system enclosure surrounded by an external environment and configured to house the first and second battery cells. The battery system additionally includes a collection bag housed within the battery system enclosure and fixed to each battery cell. The collection bag is configured to capture high-temperature gases and/or debris vented by at least one of the battery cells. The collection bag is also configured to divert the captured high-temperature gases and/or debris of each battery cell away from the other battery cell. The collection bag thereby reduces transfer of the high-temperature gases and/or debris between the battery cells and mitigates propagation of a thermal runaway event in the battery system. The collection bag is further configured to expel the captured high-temperature gases and/or debris to the external environment.
