Phase change material-based thermal energy storage
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.
