Wu et al. immersed Li-ion batteries in silicone oil, which is flowing, to improve safety and performance.

Choosing a proper cooling method for a lithium-ion (Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at a optimal range of 15 °C to 35 °C is essential to increasing safety, extending the pack service life, and reducing costs.
Results of this study include a comparison of thermal performance of battery cells by using different cases of battery pack with varying channel size and number of channels in order to get the optimized design of battery pack with liquid cooling which gives better thermal performance.
In addition, immersion cooling systems typically inhibit thermal runaway because some dielectric fluids tend to be flame retardants, thereby increasing the safety of lithium battery packs. Karimi et al. performed a thermal analysis of lithium– ion battery cells using air, a silicone oil, and water as coolants.
Even in extreme operating conditions such as a thermal runaway, direct liquid cooling has the capability to enable safe battery operation due to the high fire point and phase transition characteristics of coolants.
