A system for measuring a heat response of a battery cell includes a cell chamber configured to receive the battery cell therein. The cell chamber is configured to trigger a battery cell into a thermal runaway event while in the cell chamber, which causes the battery cell to eject an electrode winding, particles, and gas. The system also includes an ejecta bore muffler configured to receive the electrode winding, the particles, and the gas. The system also includes an ejecta basket configured to be positioned at least partially within the ejecta bore muffler. The ejecta basket is configured to capture the electrode winding while allowing at least a portion of the particles, the gas, or both to pass therethrough. The system also includes a gas collection system configured to receive at least a portion of the gas that passes through the ejecta basket.
