Is liquid immersion cooling a good option for lithium ion batteries?

With higher energy density and fast-charging demands in modern EVs and energy storage systems, traditional air and indirect liquid cooling methods struggle to keep up with thermal runaway risks and non-uniform heat dissipation. (Roe et al., Immersion Cooling for Lithium-Ion Batteries – A Review, 2022). Liquid Immerison cooling.

Can liquid immersion technology improve battery thermal management?

The promising application of liquid immersion technology in electronic equipment has also garnered increasing attention for its potential in battery thermal management. Power battery immersion liquid-cooling technology involves directly immersing the battery in dielectric liquid to dissipate heat through convection or phase-change heat transfer.

Why should a battery be cooled by a cooling liquid?

It was the first time that the battery was directly immersed into the cooling liquid, which realizes fast, direct and sufficient cooling, guaranteeing operation of the battery at its optimum temperature and effectively expanding its service life while improving safe performance of the energy storage power plant.

Why is battery immersion cooling important?

Battery immersion cooling can provide significant preventative measures to mitigate these threats [, , , ]. Gao et al. , for instance, researched a design of an emergency refrigerant spray cooling thermal management system for a battery pack.

What are liquid cooling-based battery thermal management systems (BTMS)?

Liquid cooling-based battery thermal management systems (BTMs) have emerged as the most promising cooling strategy owing to their superior heat transfer coefficient, including two modes: indirect-contact and direct-contact. Direct-contact liquid BTMs, also referred to as immersion cooling systems, have garnered significant attention.

Does battery immersion cooling increase heat transfer?

Performance of battery immersion cooling and different cooling fluids reviewed. Immersion fluids can increase heat transfer by up to 10,000 times compared to air. Thermal properties of lithium-ion batteries and heat transfer mechanisms explored. Safety implications of battery immersion cooling discussed.
