The thermal management of lithium-ion batteries (LIBs) has become a critical topic in the energy storage and automotive industries. Among the various cooling methods, two-phase submerged liquid cooling is known to be the most efficient solution, as it delivers a high heat dissipation rate by utilizing the latent heat from the liquid-to-vapor
Challenges and perspectives. LMBs have great potential to revolutionize grid-scale energy storage because of a variety of attractive features such as high power density and cyclability, low cost, self-healing capability, high efficiency, ease of scalability as well as the possibility of using earth-abundant materials.
That said, given the lower temperature difference between the surroundings and the battery, heat transfer due to radiation is neglected. Further, as a liquid-cooled TMS is examined, the priority of the current study is on the heat removed by the coolant. 2.2.2.
Liquid-cooling is also much easier to control than air, which requires a balancing act that is complex to get just right. The advantages of liquid cooling ultimately result in 40 percent less power consumption and a 10 percent longer battery service life. The reduced size of the liquid-cooled storage container has many beneficial ripple effects.
While there are pros and cons to each cooling method, studies show that due to the size, weight, and power requirements of EVs, liquid cooling is a viable option for Li-ion batteries in EVs. Direct liquid cooling requires the battery cells to be submerged in the fluid, so it''s important that the cooling liquid has low (or no) conductivity.
