Battery system enclosure with battery cell venting collection bag for thermal runaway mitigation

A motor vehicle comprising:

• a power-source configured to generate power-source torque;
• and
• a battery pack configured to supply electrical energy to the power-source, the battery pack including:
• a first battery cell and a neighboring second battery cell;
• a battery system enclosure surrounded by an external environment and configured to house each of the first and second battery cells;
• a collection bag housed within the battery system enclosure, fixed to each of the first and second battery cells, and configured to:
• capture high-temperature gases and/or debris vented by at least one of the first and second battery cells;
• divert the captured high-temperature gases and/or debris of each of the first and second battery cells away from the other of the first and second battery cells to thereby reduce transfer of the high-temperature gases and/or debris between the battery cells and mitigate propagation of a thermal runaway event in the battery system;
• and
• expel the captured high-temperature gases and/or debris to the external environment.
