As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
At low discharge rates and high ambient temperatures, the entropy heat coefficient and reversible entropy heat are crucial factors in the thermal simulation of batteries. Conceptualization, J.L.; data curation, J.G.; supervision, J.L.; writing—review and editing, J.G., Q.G., J.L. and H.W.
For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.
A key objective in the thermal design of lithium-ion batteries is to effectively mitigate heat generation and reduce the maximum temperature of battery cells under different conditions. Achieving these objectives simplifies the complexity of the thermal management system for lithium-ion batteries, leading to improved safety and performance.
They obtained that the battery maximum temperature increases with heat generation and with the decrease of Reynolds number and conductivity ratio. They found that thermal oils, nanofluids and liquid metals provide the same maximum temperature range.
Various thermal models, such as the electrochemical-thermal-coupled model and equivalent thermal circuit models, have been proposed and developed to accurately predict temperature changes and heat generation within batteries.
