Review on Porous Ceramic‐Based Form‐Stable Phase Change Materials: Preparation, Enhance Thermal Conductivity, and Application

Abstract A phase change material is an ideal energy storage material with huge latent heat and nearly constant phase change temperature, but there are serious problems in application such as leakage and low thermal conductivity. Porous ceramic matrixes are widely used in phase change material packaging because of their controllable porosity, large specific surface area, and high thermal conductivity. This paper introduces the preparation of porous ceramics and encapsulation of form‐stable phase change materials (FSPCMs) based on porous ceramics, thermal conductivity enhancement and other aspects of the comb, in addition, the applications of porous ceramic‐based FSPCMs in industrial waste heat recovery, temperature regulation of buildings, solar energy collection and storage, and battery thermal management system are summarized, in order to provide reference for the performance optimization of porous ceramic‐based FSPCMs and explore new preparation methods, finally, the challenges and future development of the FSPCMS are summarized. Porous ceramic‐based FSPCMs are expected to make major breakthroughs in the future to solve the increasingly serious energy problems.
