High thermal power density
WebNov 2, 2024 · High-bandwidth applications require small-sized power supplies, which can be achieved only with a high power density. Advertisement For high-bandwidth applications in large data centers, 5G communication, and space-graded applications like satellites, there is a huge demand for miniaturizing power supplies. WebPhase change materials (PCMs) provide a high energy density for thermal storage systems but often suffer from limited power densities due to the low PCM thermal conductivity. Much like their electrochemical analogs, an ideal thermal energy storage medium combines the energy density of a thermal battery with the power density of a thermal capacitor.
