Facile Ester‐based Phase Change Materials Synthesis for Enhanced Energy Storage Toward Battery Thermal Management

. In subsequent application studies, this material demonstrates outstanding energy storage characteristics and proposed an innovative thermal management method for batteries based on the PCM immersion technique, allowing the battery to maintain a temperature below 60 °C for 20.5 h, while the blank group rapidly reached 60 °C within 0.82 h and increased to 75 °C within 2.35 h. This approach greatly improves temperature regulation, enhances battery safety, and boosts operational efficiency, highlighting the immense potential of the material in advanced energy storage applications.
