1. A venting apparatus for battery ejecta for use in an electric vertical takeoff and landing (eVTOL) aircraft, the apparatus comprising:
a battery module, the battery module comprising a plurality of electrochemical cells, wherein the plurality of electrochemical cells are each separated by a carbon fiber barrier; and
a plurality of vent ports connected to the plurality of electrochemical cells and configured to vent the plurality of electrochemical cells using a plurality of venting paths and at least an outlet, wherein the plurality of vent ports are fluidly connected to the plurality of venting paths and the plurality of vent ports include a plurality of motion sensors to detect a thermal runaway event and the plurality of venting paths are fluidly connected to at least an outlet, wherein the plurality of motion sensors are configured to measure the same data at different instances;
a controller, wherein the controller commands an actuator to control the plurality of venting paths and change a plurality of angles of the plurality of vent ports.
