“…One of the groups of phase change materials that are used in solar installations includes inorganic salts [8]. Inorganic salts, as opposed to organic ones, are considered more environmentally friendly and safe [9], have a higher volumetric latent heat, are cheaper, more easily available, their thermal conductivity is higher, they have lower volumetric changes, and they are a non-flammable material. However, the disadvantage is that they are corrosive, they are subject to overcooling, and the volume changes are high [8].…”

“…Taking care of the technical and economic aspects, there are works devoted to improving the properties of salt hydrates. One of the most promising trends is nanoencapsulation, which improves their structural properties and reduces costs and increases the potential of their applications [4,9,10]. Research is still being undertaken to create mixtures of salt hydrates that will lower their corrosiveness, as well as reduce or stabilize supercooling and volume changes [9][10][11][12].…”

The aim of this article is to assess the potential impact of inorganic salt hydrates used as PCM material in solar installations on the environment and human health and to assess the society’s approach to this technology. The properties of salt are discussed in two ways: first, by analyzing the environmental and health problems caused by chemical hazards on the basis of the available material safety data sheets. Secondly, by analyzing the potential disadvantages of salt hydrates in terms of environmental hazards based on the results of experimental studies available in the literature. Then, using questionnaires, the public approach to solar installations with a built-in converter containing salt hydrates is assessed. Disodium hydrogen phosphate dodecahydrate turned out to be the most prospective salt in terms of environmental, thermophysical, and economic properties for use in solar installations. Understanding the attitudes of the local community toward technologies using inorganic salt hydrates will enable appropriate action to be taken in the future to promote their development. Surveys have shown great public concern about their impact on the environment and human health. In this regard, it is necessary to implement information and promotion activities.

“…Furthermore, hydrated salt solutions are highly polarized and water-soluble, making the preparation of hydrated salt capsules very difficult. 39 A few investigations were conducted about the hydrated salts NePCMs for BTMs. 40 At present, most of the hydrated salt phase change nanocapsules use inorganic materials as shells, 41 resulting in poor cycling stability, while using organic materials as the shell layer leads to a reduction in thermal conductivity.…”

Herein, silicon carbide (SiC)-doped hydrated salt phase change nanocapsules (NePCMs) with enhanced thermal conductivity and nonflammability were synthesized using a simple method for battery thermal management systems (BTMs). The additional amount of SiC played a critical role in the heat capacities of hydrated salt nanocapsules. The resultant phase change nanocapsules have a latent heat of over 145.6 kJ/kg, good encapsulation of around 60%, thermal conductivity of 0.51 W m–1 K–1, as well as good leak-proof property and thermal cycle stability. More importantly, due to the perfect core–shell structure, the hydrated salt nanocapsules exhibited a significant enhancement in corrosion protection and flame-retardant property. High-rate charging test at ambient temperature showed that the NePCMs cooling was able to maintain a low maximum temperature during the melting process and keep the battery temperature within a safe range. In conclusion, the phase change nanocapsules developed in this work may have great promise in the field of safe and high-efficient battery thermal management.

Herein, the synthesis of a novel microencapsulated phase change material via a sol–gel method is presented, featuring disodium hydrogen phosphate dodecahydrate as the core and a SiO2/graphene oxide composite as the shell. The morphology and core–shell microstructure of the synthesized microcapsules are characterized using scanning electron microscopy. The phase change performance and thermal stability are evaluated by differential scanning calorimetry and a high/low temperature test chamber, respectively. Energy dispersive X‐ray spectroscopy and Fourier transform infrared spectroscopy are employed to determine the chemical composition of the microcapsules. The findings reveal that the MEPCM exhibited a high melting enthalpy of 174.3 J g−1. The degree of supercooling is reduced by 2.1 °C, and after 600 thermal cycles, the phase change enthalpy of the microcapsules showed a minor decrease of ≈6.0%. Notably, the thermal conductivity of the microcapsules is significantly enhanced, increasing by up to 51.8%. When integrated into the thermal management systems of lithium‐ion batteries, the MEPCM effectively maintained the battery temperature below 46 °C under a 3 C charging rate. In summary, these results suggest that the hydrated salt microcapsule with its hybrid silica and graphene oxide shell is a promising material for the thermal management of lithium‐ion batteries.
