Role of phase change materials in thermal energy storage:
Still, when the material is at a higher phase change temperature, the stored heat is 1.5 times the thermal density of the sensible heat storage. The reason for choosing composite materials is that filling and emptying the thermal system is time-constrained, thereby mandating the transfer of heat into and out of the system rapidly [227] .
