A two-phase immersion liquid cooling system was established for large format Li-ion battery efficient heat dissipation. The maximum temperature and temperature variation in battery cell have been successfully limited at high discharge C-rates. The factors influencing the pool boiling in the cooling of Li-ion batteries were discussed.
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.
Nanotechnology-enhanced Li-ion battery systems hold great potential to address global energy challenges and revolutionize energy storage and utilization as the world transitions toward sustainable and renewable energy, with an increasing demand for efficient and reliable storage systems.
They found that the thermal management achieved through single-phase liquid cooling method can effectively and safely maintain desired temperatures within battery cells and modules. G. Satyanarayana et al. studied the immersion cooling performance of lithium-ion batteries using mineral oil and therminol oil.
Non-direct contact liquid cooling is also an important way for battery cooling. According to Sheng et al.'s findings , utilizing a cellular liquid cooling jacket for cylindrical lithium-ion battery cooling maintain keep their temperature below 39 °C during discharge at a rate of 2.5C, surpassing the results obtained in this study.

It is evident that the utilization of a two-phase immersion liquid cooling system enables consistent maintenance of battery temperatures at approximately 33–35 °C throughout the alternating charge/discharge process.
