Volume 2, Issue 8, 18 August 2021, 100540 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.
Why are phase change materials difficult to design?
Phase change materials (PCMs), which are commonly used in thermal energy storage applications, are difficult to design because they require excellent energy density and thermal transport, both of which are difficult to predict from simple physics-based models.
Do high power output thermal storage systems need to sacrifice energy density?
Therefore, high power output thermal storage systems may need to sacrifice energy density and vice versa. At large times, the flux is especially dependent on the thermal conductivity and heat capacity of the liquid.
