熔融盐是一种非常有前景的高温液体传热蓄热工质，在太阳能热发电、余热回收及工业热利用方面有显著的优势，但是熔融盐本身存在导热性能不高等问题。本文对纳米复合相变材料固液相变储能过程的若干最新研究进行了回顾，综述了熔融盐纳米固液相变复合材料国内外研究现状及发展趋势，最后对纳米复合相变材料固液相变储能过程的未来发展和重点研究方向进行了展望，认为主要解决纳米复合材料内熔化相变传热双温度模型的建立及求解、NC-PCM的制备工艺、金属纳米粒子的团聚性及NC-PCM蓄热器的热循环实验等方面的问题是未来研究的重点。

Mixed molten salts are considered as promising media for both heat transfer and thermal energy storage and they have obvious advantages in solar thermal power generation, waste heat utilization and industrial process heat use. However, molten salts phase change materials still have disadvantages of low thermal conductivity. Recent studies of solid-liquid phase change energy storage processes and the state-of-the-art development of the nanocomposite phase change material were reviewed. According to the review of the future development and important research direction of solid-liquid phase change energy storage processes of nanocomposite phase change materials, it is necessary to conduct the research in various aspects including the establishment of two temperature model of phase change heat transfer in the nanocomposite melting, NC-PCM mixing process, aggregation of metal particles and thermal cycling test of NC-PCM storage unit problem.
