Claim 7:
8. A method of manufacturing a battery pack for an electric aircraft comprising:
housing, using a battery module, a battery unit, wherein the battery module comprises:
a plurality of battery cells, wherein each of the plurality of battery cells has a cylindrical body and opposed first and second ends; and
a cooling plate, in thermal communication with the plurality of battery cells;

placing a firewall to intercept ejecta debris from the plurality of battery cells, wherein the firewall is disposed proximal and substantially parallel to the first or second ends of the battery cells;
configuring an airgap to extend between the firewall and the first and the second ends of the battery cells;
configuring a wall of the battery pack positioned adjacent to the plurality of battery cells and perpendicular to the firewall, the wall defining a headspace in fluid communication with the airgap and an ejecta vent,
wherein the airgap is configured to receive and contain a portion of the ejecta debris between the firewall and the battery cells during a thermal runaway event.
