Abstract Finding inorganic materials with significant Al ion mobility could push the development of alternative rechargeable batteries, as they could potentially serve as solid electrolytes or intercalation cathodes. While for single‐ and double‐charged ions numerous solid electrolytes are known, the situation is rather unclear and only sparingly researched for ions with a charge higher than two. To assist in the systematic analysis, compounds described in literature as solid electrolytes or intercalation materials for Al3+, as well as some materials generally known for high mobilities for multivalent ions, are critically reviewed and analyzed by the bond‐valence energy landscape approach. For this purpose a thorough list of investigated cathode materials for rechargeable Al batteries is provided first. While it is demonstrated that solid electrolytes for Al3+ cannot be unequivocally identified in literature yet, the analysis of the intercalation cathodes reveals promising structural motifs for comparatively fast Al diffusion, which can be used for the analysis, comparison and design of new promising materials. Furthermore, chances and limits of the bond‐valence energy analysis for high‐valent battery materials are exemplarily shown. Thus, this work aims at encouraging more theoretical and experimental work on Al battery materials and provides guidelines for doing so.

结晶固体中的 Al3+ 迁移率：批判性审查和分析

摘要 寻找具有显着 Al 离子迁移率的无机材料可以推动替代可充电电池的发展，因为它们有可能用作固体电解质或插层阴极。虽然对于单电荷和双电荷离子，有许多固体电解质是已知的，但情况尚不清楚，并且仅对电荷高于 2 的离子进行了少量研究。为了协助系统分析，文献中描述为固体电解质或 Al3+ 的嵌入材料的化合物，以及一些通常以多价离子的高迁移率而闻名的材料，通过键价能量图谱方法进行了严格审查和分析。为此，首先提供了一份完整的可充电铝电池阴极材料清单。虽然已经证明 Al3+ 的固体电解质在文献中还不能明确确定，但对插层阴极的分析揭示了相对较快的 Al 扩散的有希望的结构基序，可用于分析、比较和设计新的有前途的材料。此外，示例性地显示了高价电池材料的键价能量分析的机会和限制。因此，这项工作旨在鼓励对铝电池材料进行更多的理论和实验工作，并为此提供指导。示例性地显示了高价电池材料的键价能量分析的机会和限制。因此，这项工作旨在鼓励对铝电池材料进行更多的理论和实验工作，并为此提供指导。示例性地显示了高价电池材料的键价能量分析的机会和限制。因此，这项工作旨在鼓励对铝电池材料进行更多的理论和实验工作，并为此提供指导。
