Abstract Mitigating thermal runaway propagation of batteries by applying thermal barrier to block heat transfer will inevitably weaken heat dissipation. Low-thermal-conductive phase change material (LTC-PCM) is a promising candidate of thermal barrier because of its high latent heat. While limited research is found related to how much effect does thermal barrier on performance of battery thermal management system (BTMS), especially when liquid cooling is applied. The present work compares BTMS performance of prismatic battery module with LTC-PCM, low-thermal-conductive material (LTCM), and high-thermal-conductive pad (HTCP), also further investigates BTMS performance with different width of LTC-PCM and flow rate of heat transfer fluid (HTF). The results indicate average battery temperature (Tave) in modules with the three materials follows the sequence: LTC-PCM
