Thermal energy storage system comprising encapsulated phase change material
Methods of encapsulating a phase change material in a capsule including suspending a particle of the phase change material in an air stream, coating an entire surface of the suspended particle with at least one layer of a sacrificial compound, coating an entire surface of the layer of the sacrificial compound with at least one layer of a second material, and encapsulating the phase change material within a shell formed by the second material. The step of encapsulating comprising heating the particle coated with the sacrificial compound and the second material, thermally decomposing the sacrificial compound, and vaporizing the sacrificial, wherein the sacrificial compound has a decomposition temperature less than a phase change temperature of the phase change material and a phase change temperature of the second material.
