Graphene phase change solar container
In this new structure, graphene can directly absorb and store solar energy in the paraffin PCMs by means of phase change heat transfer. The porous structure provided good heat conduction, and the large surface area increased the loading capacity of solar thermal storage. . In this work, new form-stable solar thermal storage materials by impregnating paraffin PCMs within porous copper–graphene (G–Cu) heterostructures were designed, which integrated high thermal conductivity, high solar energy absorption, and anti-leakage properties. In this work, new form-stable solar. . This research explores the integration of an enhanced thermal energy storage composite graphene-paraffin phase change material (PCM) into an IoT-enabled box-type solar cooker. The incorporation of this advanced PCM significantly improves the system heat retention capability and effectively extends. . Phase-change thermal batteries for renewable energy storage and waste heat recovery demand high energy density and fast charging1–5, which are mutually exclusive because phase-change materials (PCMs) with high melting enthalpy are usually poor heat conductors6–8. The charging rate can be improved.
