报告摘要：
Phase change materials (PCMs) showpromises for thermal energy storage (TES) owing to their substantial latentheat during phase transition. However, the power density and overall storageefficiency are constrained by low thermal conductivity, leakage issues andphase instability of most viable PCMs. The urgency surrounding the explorationof the Next Generation of Phase Change Materials is rooted in the contemporaryenergy challenges faced by the global community. Though PCM was first appliedtwo decades ago, it remains an affordable, sustainable, and reliable solutionfor numerous TES and regulation problems. With meticulous exploration byresearchers on PCM, every confine of PCM paves the way for a new class of PCMwith improved performance and ease of operation. Timely research in this domainis crucial to harnessing the full potential of PCMs and integrating them intodiverse sectors, ranging from buildings and transportation to electronics andbeyond. As an emerging trend, the primary issues associated with PCMs arerefining thermodynamic parameters, optimizing the kinetics of isomerization andphase change process, enhancing energy conversion efficiency; and tuning theabsorption spectrum, liquid leakage and low thermal conductivity, disposal ofnanomaterial dispersed PCM after long term operation which causes environmentalissues. Considering the potential of PCMs and their footprints as new-classPCMs resolving the issue mentioned above, there is the utmost need forresearch's focusing on next-generation PCMs.
Herein, I demonstrate the in-depth discussion ofthe intermolecular interaction mechanism involved in the energy storage abilityof PCM and confers the primary confinement associated with PCM.
