PCM heat storage technology belongs to latent heat storage [11], and it can be classified as solid-solid, solid-liquid, gas-liquid, and solid-gas on the basis of the phase change characteristic. Due to the storage difficulty of gas, there are mainly solid-liquid PCMs and solid-solid PCMs in actual application [12].
PCMs simultaneously change the phase from solid to liquid (energy absorbing) and liquid to solid (energy releasing). Therefore, a PCM should be thermally stable even after few cycles of operation. However, some researchers [23], [96], [113], [211] reported that most of the PCMs are thermally not stable after few cycles of operation.
