Abstract
This research is focused on the preparation and characterization of new graphite-based phase change material (PCM) for energy storage application. Characterization like microstructure and chemical composition were discussed using XRD and SEM with EDX. Added to the above thermal conductivity of the prepared samples were studied. This PCM is based on nitrate fillers with expanded graphite (EG). Samples were synthesized with EG concentration of 3%, 5%, 7% and 9 wt%. This composite PCM consists of salts and graphite or eutectic. The SEM images shown the uniform distribution of EG into the nitrate based PCM. Thermal conductivity measurement shows the thermal conductivity is increased with EG concentration. The obtained results suggest that the graphite-based nitrate PCM is a promising element to use in high thermal energy storage applications.
