While phase change material (PCM) heatsinks and energy storage modules have been shown to act as highly efficient transient energy storage components, they have traditionally been limited by the rate at which heat is absorbed into the PCM. This limits the ability to effectively recover waste heat or to manage environmental climate control in building settings at sufficiently high rates of energy storage. Composite thermal energy storage (TES) materials, consisting of highly thermally conductive elements and PCMs can overcome some of the challenges presented by the slow rate of heat absorption in PCMs. However, the application of these components is limited by a lack of coherent design guidelines. Here, we present an experimentally and numerically validated design framework based around the concept of PCM composites, where the effective thermal properties of a composite are dictated by constitutive relationships relating the composite structure to its transport properties.
