摘要：

金属基相变材料由于具有储能密度高、热稳定性好、热导率高等优点，在潜热热能储存系统中具有极大的优势。本文回顾了金属基相变材料的发展历程，归纳了金属基相变材料的性能参数，总结了各种热物性的测量方法，探讨了金属基相变材料与容器材料的相容性问题，分析了金属基相变材料在太阳能热发电、工业余热回收和电力削峰填谷中的应用前景。金属基相变材料的高温腐蚀性是目前限制其在热控制中应用的主要因素。为了实现金属基相变材料的广泛应用，需要重点解决金属基相变材料的封装问题。

Abstract:

Metal-based phase change materials (PCMs) are superior to other phase change materials in latent thermal storage system owning to their advantages such as high heat storage density, good thermal stability, excellent conductivity coefficient, and so on. This paper briefly reviews the development of metal-based PCMs,
as well as the thermophysical properties and characterization methods of metal-based PCMs. The compatibility between metal-based PCMs and container materials was discussed through a close exploration on the recent literatures. The prospects of metal-based PCMs in solar thermal power generation, high temperature waste heat recovery and load shifting in electric power were also analysed. It is summarized that the compatibility between metal-based PCMs and container at high temperature is limiting their potential applications in various thermal control systems. The future work should be focus on the reliable encapsulation of metal-based PCMs in order to realize its comprehensive applications.

Key words: metal-based phase change materials, thermophysical properties, compatibility, solar thermal power generation, waste heat recovery
