Abstract Recently, inorganic thermal energy (TES) storage materials to support renewable energy implementation are being developed, and lithium salts have been showing thermal properties suitable for latent storage applications. There are three main technologies to achieve TES: sensible, latent, and thermochemical energy storage. Latent heat storage materials or phase change materials (PCMs) can store large amounts of heat per volume and they can be applied at a certain temperature, depending on the desired application. Lithium compounds for sensible storage have been reviewed in previous publications. Their use in latent heat storage applications is increasing but scarcely documented; while new latent heat storage Li materials appear consistently, the information on them is still dispersed. Therefore, the main objective of this study is to discuss lithium compounds used, proposed or analyzed for latent heat storage (LHS) and their possible applications. Lithium salts thermophysical properties, such as density, melting temperature and latent heat were tabulated as found in literature. Binary salts presented attractive heat of fusion values over 130 kJ kg−1 in a wide range of temperatures. Moreover, the increase of stability of multi-component PCM systems due to the insertion of lithium compounds was confirmed. The technologies to produce lithium are improving and, if the demand increases, prices could decrease in the near future. Therefore, the availability of lithium materials was also analyzed in this study. Finally, potential applications of these thermal storage materials, such as heated underwater diver suits, portable thermal conditioning jackets, solar receiver space, Stirling engines, etc. were assessed.

基于无机锂盐的潜热蓄热材料开发进展

摘要 最近，正在开发支持可再生能源实施的无机热能 (TES) 存储材料，并且锂盐已显示出适合潜在存储应用的热性能。实现 TES 的主要技术有三种：显能、潜能和热化学储能。潜热储存材料或相变材料 (PCM) 可以在单位体积内储存大量热量，并且它们可以在特定温度下应用，具体取决于所需的应用。用于敏感存储的锂化合物已在以前的出版物中进行了审查。它们在潜热储存应用中的使用正在增加，但几乎没有记录；虽然新的潜热蓄热锂材料不断出现，但关于它们的信息仍然很分散。所以，本研究的主要目的是讨论用于、提议或分析用于潜热储存 (LHS) 的锂化合物及其可能的应用。如文献中所见，锂盐的热物理性质，例如密度、熔化温度和潜热被制成表格。二元盐在很宽的温度范围内呈现出超过 130 kJ kg-1 的有吸引力的熔化热值。此外，由于锂化合物的插入，多组分 PCM 系统的稳定性增加得到证实。生产锂的技术正在改进，如果需求增加，价格在不久的将来可能会下降。因此，本研究还分析了锂材料的可用性。最后，这些蓄热材料的潜在应用，例如加热水下潜水服，
