Abstract Thermal management systems for power batteries based on phase change materials (PCM) are limited by low heat transfer efficiency, leakage issues, and high rigidity, most of them cannot meet the needs all‐climate thermal management. A double‐layer flexible material (FPCM) sleeve structure is proposed in this study first time. Innovations both design have enhanced adaptability system. The outer layer FPCM achieves conductivity (4.23 W m −1 K ) electrical (0.95 S ), inner insulation (22.76 MΩ) flexibility, contact resistance (TCR) between battery measured to be only 0.15 °C , significantly improved performance. Experimental results show that at 30 ambient temperature, 5 C discharge, system reduces maximum temperature 14.5 °C, from 61.4 46.9 compared natural convection. Additionally, during heating, heating rates 7.0, 8.3, 8.7 min −20, −10, 0 respectively, extending discharge duration 32.5%, 65.9%, 33.6%.
