Abstract: The combined cooling mode of phase change material and liquid cooling is an effective method for thermal management of li-ion battery at present. By comparing the battery temperature changes under the three working conditions of li-ion batteries：natural convection cooling, phase change material cooling，phase change material and liquid cooling combined cooling，the influence of phase change material and liquid cooling combined cooling on the thermal management and electrochemical properties effects of battery was analyzed. The results showed that the combination of phase change materials and liquid cooling can effectively reduce the temperature of li-ion battery, ensure that the battery is at normal working temperature, and the electrochemical performance of the battery is more stable.

Key words: li-ion battery, phase change material, liquid cooling, electrochemical performance
