“…During the reaction, Co 3 O 4 is released from the decomposition of LiCoO 2 which then reacts with the Li 2 CO 3 to form LiCoO 2 with improved cycling stability. The melting point of Li 2 CO 3 is 723°C ( Navarrete et al., 2022 ), therefore for improved cycling stability, experiments that utilize Li 2 CO 3 as a lithium resource need to be performed at temperatures higher than 723°C.…”

“…9 These PCMs are best for storing thermal energy in the low-temperature range (below 120 C). Inorganic PCMs, on the other hand, include salt hydrates 10 (generally used for low temperature applications), nitrates, 11 carbonates 12 (for medium temperature applications, that is, below 300 C); chlorides 13 and metals 14 (suitable for high temperature applications). Of all inorganic PCM materials, nitrate salts show desirable properties such as higher storage density per unit volume, adequate thermal conductivity and more stability, causing them to be chosen as potential candidates.…”

Summary Using a thermogravimetric analyzer, the thermal stability of pure eutectic phase change material (PEPCM) (LiNO3 + NaCl) and composite eutectic PCM (CEPCM) mixture (ie, PCM containing 9% expanded graphite [EG]) was examined. PEPCM and CEPCM degradation kinetics were studied using model free kinetics methods. The activation energy of both PCM samples was evaluated using the Kissinger‐Akahira‐Sunose (KAS), Flynn‐Wall‐Ozawa (FWO), Starink, Friedman and Vyazovkin kinetic models. The calculated activation energies for Vyazovkin, Frideman, Ozawa, KAS and Starink techniques for PEPCM were 80.62‐149.2, 108.1‐180.18, 83.74‐136.17, 73.55‐127.02 and 74.64‐149.9 kJ/mol, respectively. Likewise, the activation energy of CEPCM vary between 59.4‐161.41, 83.97‐188.69, 57.1‐147.32, 54.19‐137.43 and 55‐160.65 kJ/mol. Hybrid neural networks such as ANN‐PSO and ANFIS were used to model the degradation of PCM samples. The type of PCM, the heating rate, and the temperature were applied as input parameters, while the sample's mass loss was utilized as an output parameter. The created hybrid models are capable of effectively predicting experimental TGA data.

“…Currently, the most commonly used heat transfer fluid in CSP collectors is an eutectic mixture of biphenyl and diphenyl oxide that is capable of reaching temperatures of up to 400 • C without decomposing [32]. In the literature, the vast majority of nanofluid studies use water [33] as the base fluid or molten salts for high temperature applications [34,35] instead of this kind of thermal oil [36] or silicone oils which are being studied in recent times [37,38]. In addition, it is necessary to open up the research area to other nanoparticles besides the typical metals and metal oxide already studied [39][40][41].…”
