Quantifying Vent Gas Production in Lithium-Ion Batteries

Presented by: Robert Kennedy, Graduate Research Assistant, University of Texas at Austin Fire Research Group

This presentation shows methods for measuring the gas release. Pressure vessel experiments with pouch cells were conducted to understand the total and rate of release of vent gas from varying cell capacities, chemistries, and SOCs. Cell arrays were used to understand how the vent gas production evolves as the failure event propagates. This determined how the changing environment in which a cell fails influences the resulting gas production. The calculated rate from the experiments was tested using a CFD model for the vessel to understand the measurements taken as they correspond to the calculated volume production.
