Li4(OH)3Br-Based Shape Stabilized Composites for High-Temperature TES Applications: Selection of the Most Convenient Supporting Material

“…These materials are characterized by good thermal stability, a high adsorption capacity and low cost. Halloysite nanoclay is used generally as a nucleating agent to mitigate the supercooling phenomena of the hydrate PCMs and is applied for cold storage [ 37 , 38 ] Other supporting materials including refractory oxides (MgO, Al 2 O 3 , SiO 2 , mullite), SiC and Ca(OH) 2 [ 11 , 13 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ]. The compatibility and good wettability with nitrates, carbonates, chlorides and sulfates have been proven for most of them.…”

“…Moreover, the wettability with molten salts is good, and they can support temperatures above 1000 • C. However, they have low values of thermal conductivity (<0.15 W/m/K), and the melting infiltration route is needed for ss-composite preparation, which is more expensive than the cold compression method. [11,13,[39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. The compatibility and good wettability with nitrates, carbonates, chlorides and sulfates have been proven for most of them.…”

Hierarchical macro-nanoporous metals for leakage-free high-thermal conductivity shape-stabilized phase change materials

“…Their use is beneficial for applications such as hybrid heating systems [19], buildings [20,21,22], electronic components [23], Li-ion batteries thermal management [24,25], photovoltaic modules [26], thermoregulating textiles [27,28], solar-driven cookers [29], water heaters [30] and refrigerators [31]. Different composites were used for this purpose such as binary fatty acid/diatomite [32], aluminum foam/ paraffin [33], NaNO3/Ca(OH)2 [34],…”

Toward Tailoring Chemistry of Silica-Based Phase Change Materials for Thermal Energy Storage

“…Undoubtedly, highly thermally conductive carbon materials can accelerate thermal transfer and boost the charging/discharging rates of composite PCMs. In this regard, several reviews have been presented ( Chen et al., 2020b ; Huang et al., 2019 ; Ibrahim et al., 2017 ; Lin et al., 2018b ; Tong et al., 2019 ; Wu et al, 2019 ; Yang et al., 2019a ; Yu et al., 2019 ). Considering large-scale practical applications of composite PCMs, there are some negative factors in graphene- and CNT-based composite PCMs, such as complex preparation process, low yield, and high cost.…”

“…However, the discontinuous supply and awful waste of thermal energy normally reduce the energy utilization efficiency and cause a gap between energy demand and supply in time and space. To improve the thermal energy utilization efficiency and bridge the gap, thermal energy storage techniques (thermochemical energy storage (TCS), sensible heat storage (SHS), and latent heat storage [LHS]) have been extensively explored since the last century (Gao et al, 2018;Huang et al, 2019;Li et al, 2019;Pielichowska and Pielichowski, 2014;Umair et al, 2019;Yang et al, 2019c;Yu et al, 2019). Among thermal energy storage techniques, TCS has the highest thermal energy density, which is around 5 to 10 times higher than SHS and LHS (Pardo et al, 2014;Shchukina et al, 2018).…”
