Abstract: Thermal runaway and its propagation within lithium-ion battery systems pose significant challenges to widespread adoption in electric vehicles and energy storage systems. Deploying a thermal barrier between adjacent batteries is a common and effective strategy to prevent thermal propagation. This experimental study evaluates the inhibitory effect of nanofiber aerogel on thermal propagation within high-energy-density lithium-ion battery modules. The results indicate that increasing the thickness of nanofiber aerogel prolongs the average time interval between thermal runaway propagation events between adjacent batteries and increases their peak temperature difference, while the maximum surface temperature of each battery exhibits an overall downward trend.
