Latent heat thermal energy storage (LHTES) technology is viewed as an effective measure to alleviate the contradiction between energy supply and demand.It uses phase change materials (PCMs) to absorb/release heat during phase change process to achieve energy storage and release.This technology has great application potential in building energy conservation,greenhouse temperature control and temperature-adjustable clothing.In this paper,the types and characteristics of shaped-stabilized PCMs (SSPCM) were summarized.The preparation methods and thermal storage properties of porous-based SSPCM,microencapsulated SSPCM and polymer-based SSPCM were reviewed.In the meanwhile,the problems in the preparation process of SSPCM were analyzed,and the methods of enhancing heat transfer were introduced.Finally,the focus of future research work was discussed and the development prospects of SSPCM in the future were pointed out.
