Compared with non-phase change thermal energy storage in A-CAES, high heat storage density and temperature stability of phase change materials (PCMs) make it superior to the former [17], [18], [19].

The phase change hysteresis decreases from 4.25 °C at 50 °C to 1.52 °C at 80 °C. In addition, at high temperatures, such as 70 °C and 80 °C, it does not vary much in the degree of phase change hysteresis. The results show that the binary composite phase change material generally has phase change hysteresis characteristics, and the …
