Phase Change Energy Storage Technology (PCES) is a revolutionary approach to energy storage that leverages the substantial latent heat absorbed or released during the phase transition of phase change materials (PCMs). These materials exhibit a unique characteristic of maintaining a nearly constant temperature throughout their phase change process, which makes them highly efficient for energy storage and release when temperatures fluctuate. This technology has emerged as a pivotal area of research in the field of thermal energy management, particularly in cooling and heat storage applications. Over the past few years, the integration of PCMs into various sectors, including building energy conservation, industrial waste heat recovery, and solar energy utilization, has achieved significant milestones.

The solid-liquid phase transition of PCMs imparts a degree of fluidity, which underscores the importance of package in the thermal management of these materials. Effective package is crucial to prevent the leakage of liquid PCMs while preserving their shape and structural integrity. Our commitment to advancing the field extends to the research and development of innovative package techniques and the creation of multifunctional composite energy storage materials. These advancements aim to provide robust package solutions that minimize PCM leakage, ensuring the maintenance of optimal thermal management and structural performance.
