“…In recent years, mobile thermal energy storage technology (TEST) based on PCMs has appeared on the market, which can adapt to the dynamic needs of customers by flexible distribution, and is considered as one of the most promising TESTs. According to their sources, PCMs can be divided into inorganic PCMs and organic PCMs. − Among them, organic PCMs are widely used in waste heat recovery due to their advantages of high energy storage density, excellent thermochemical stability, low corrosion, environment-friendliness, and economy. − However, most organic PCMs are typical “solid–liquid” PCMs, and they face problems such as leakage and slow charging/exothermic rate in practical applications . Due to the strong capillary adsorption, the porous materials (grapefruit peel, melamine foam, graphene, − expanded graphite, etc.)…”
