Detection of Li-ion battery failure and venting with ...

01/02/2021· Finally, CO 2 is found in the cell leakage gas, so a CO 2 sensor can be used to detect a slow leakage. Carbon Monoxide (CO): CO was found in large amounts in the vent-gas of battery abuse tests. However, the concentration of CO decreased for cells with lower SOC [ 40 ] and in the LFP cell thermal runaway case [ 21 ], so CO is considered inconsistent regarding detection.
