According to the material property, thermal energy storage can be classified as sensible heat storage, thermochemical heat storage and latent heat storage [3]. The classification of thermal energy storage materials is shown in Fig. 1. Sensible heat storage is achieved by changing the temperature of the storage material without changing its phase.
The traditional way of heat storage based on physical changes cannot fully meet the actual demand of energy storage, so higher energy storage density media were studied. Salt hydrate is a kind of inorganic material with high heat storage density, no pollution, low cost and safety, which has great application potential in the field of phase change heat
