Abstract
A thermal energy storage composite pellet-shaped product of about 1/8 inch to 1 inch in size, formed of an outer seamless shell member which defines a cavity that permanently encases a phase-change composition, the composition being present in a quantity such that the total volume of the composition, whether in its solid form, liquid form, or both forms as in its transition state, never exceeds the volume of the cavity; and a process for making the product which includes using the phase-change composition in a compacted powder form as cast about which the shell member is formed by roll-coating steps.
