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.
We demonstrate a thermal energy storage device using phase change material (PCM). The power density is 0.58 W/cm 3, higher than other types of PCM heat sinks. The high performance is enabled by novel additively manufactured geometries. We measure and calculate cooling capacity, time constant, and energy density.

We measure and calculate cooling capacity, time constant, and energy density. Thermal energy storage using phase change materials (PCMs) is an effective way to store thermal energy.
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.
Advanced phase change energy storage technology can solve the contradiction between time and space energy supply and demand and improve energy efficiency. It is considered one of the most effective strategies to utilize various renewable energy in energy saving and environmental protection.
Among the various non-equilibrium properties relevant to phase change materials, thermal conductivity and supercooling are the most important. Thermal conductivity determines the thermal energy charge/discharge rate or the power output, in addition to the storage system architecture and boundary conditions.
