Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
Application of phase change energy storage in new energy: The phase change materials with appropriate phase change temperature should be selected according to the practical application. The heat storage capacity and heat transfer rate of phase change materials should be improved while the volume of phase change materials is controlled.
Unlike traditional phase change energy storage tanks, in which PCMs are uniformly distributed across the water tank, the PCMs in the new design are centrally arranged on one side, and a vertical baffle is provided to divide the water tank into a phase-change zone and a non-phase-change zone.
In the phase transformation of the PCM, the solid–liquid phase change of material is of interest in thermal energy storage applications due to the high energy storage density and capacity to store energy as latent heat at constant or near constant temperature.
