Phase change materials have potential uses in battery thermal management because of their controllable phase change temperature and high latent heat. However, the application of phase change materials is limited by their strong rigidity, difficult assembly, high contact thermal resistance, low thermal conductivity, and leakage. In this study, a novel flexible composite phase change material (CPCM) with good mechanical properties is prepared, which can maintain flexibility at room temperature and shape stability at high temperatures. A thermoplastic styrene-based polymer (TPS) is used as the support material, paraffin is used as the phase change material, and expanded graphite is used as the reinforced thermal conductive filler. Results show that the composites have good flexibility and extensibility at room temperature and can maintain good shape stability at 60 °C and certain pressure. The contact thermal resistance of CPCM is 50% of the contact thermal resistance of similar materials. Thermal management experiments of single battery and square battery modules are designed. After six cycles of 2.5C high-rate discharge, the maximum temperature of the battery module cooled by CPCM i
