复合氢化物具有与能量存储相关的功能，例如i）固态氢存储，ii）电化学锂存储，以及iii）快速锂离子和钠离子传导。本文报道了基于复合氢化物的快速锂离子导体开发的最新进展。还检验了在全固态锂充电电池中使用它们作为电解质的有效性。发现不仅被覆氧化物而且裸露的硫化物都可用作正极活性材料。给出了与复合氢化物中快速钠离子电导率相关的结果。在最后一节中，讨论了高能量密度电池组件以及液态和固态电解质镁离子电池的未来前景。
Complex hydrides have energy storage‐related functions such as i) solid‐state hydrogen storage, ii) electrochemical Li storage, and iii) fast Li‐ and Na‐ionic conductions. Here, recent progress on the development of fast Li‐ionic conductors based on the complex hydrides is reported. The validity of using them as electrolytes in all‐solid‐state lithium rechargeable batteries is also examined. Not only coated oxides but also bare sulfides are found to be applicable as positive electrode active materials. Results related to fast Na‐ionic conductivity in the complex hydrides are presented. In the last section, the future prospects for battery assemblies with high‐energy densities, and Mg ion batteries with the liquid and the solid‐state electrolytes are discussed.
