Thermal property measurement and heat storage analysis of LiNO3/KCl – expanded graphite composite phase change material

Design and thermal properties of a novel ternary chloride eutectics for high-temperature solar energy storage

“…The previous work [13] reported that the thermal stability of this kind of ternary molten salts was not good when exposed to air, which mainly attributed to the reactions between MgCl 2 and moisture from atmosphere [22]. In order to test the thermal stability of SYSU-C4 under real operation condition and reduce the impacts of moisture and purge stream, about 40 g SYSU-C4 were put into alumina crucible with a lid.…”

“…Chlorides are attractive for high-temperature thermal energy storage due to their low cost, high latent heat, appropriate operating temperature (400-850°C), and high thermal stability, although slightly corrosive [13]. However, numerous time-consuming experiments were required to resolve the eutectic point corresponding to the optimized composition of salt mixtures.…”

Experimental investigation on the thermal performance of a heat sink filled with porous metal fiber sintered felt/paraffin composite phase change material

“…Graphite matrices and metal foams are the most commonly used materials. Huang et al [19] indicated that the thermal conductivities of the LiNO 3 /KCl-expanded graphite (EG) composite phase change material were 1.85-7.56 times higher compared with the eutectic LiNO 3 /KCl and the conductivity value varied with the EG mass content and the apparent density of the composite. Ling et al [20] investigated the synergetic effect of the mass fraction of paraffin in the paraffin/EG composite PCM and the packing density of the composite in a power batteries thermal management system.…”

Enhanced thermal conductivity of waste sawdust-based composite phase change materials with expanded graphite for thermal energy storage

“…Due to the porous structure and enhanced thermal conductivity of expanded graphite (EG), many researchers have employed two or more materials to prepare composite shape-stable phase change materials (e.g., PCMs, EG) (Zhao et al 2011;Zhong et al 2010;Sarı and Karaipekli 2007;Zhang et al 2012;Wang et al 2014), indicating that efficient enhanced thermal conductivity occurred in composite shape-stable phase change materials. Some reports have suggested that EG has great application potentials in the field of phase change materials (Huang et al 2014;Tian et al 2015).…”
