Aluminum‐ion batteries (AIBs) are regarded as viable alternatives to lithium‐ion technology because of their high volumetric capacity, their low cost, and the rich abundance of aluminum. However, several serious drawbacks of aqueous systems (passive film formation, hydrogen evolution, anode corrosion, etc.) hinder the large‐scale application of these systems. Thus, nonaqueous AIBs show incomparable advantages for progress in large‐scale electrical energy storage. However, nonaqueous aluminum battery systems are still nascent, and various technical and scientific obstacles to designing AIBs with high capacity and long cycling life have not been resolved until now. Moreover, the aluminum cell is a complex device whose energy density is determined by various parameters, most of which are often ignored, resulting in failure to achieve the maximum performance of the cell. The purpose here is to discuss how to further develop reliable nonaqueous AIBs. First, the current status of nonaqueous AIBs is reviewed based on statistical data from the literature. The influence of parameters on energy density is analyzed, and the current situation and existing problems are summarized. Furthermore, possible solutions and concerns regarding the construction of reliable nonaqueous AIBs are comprehensively discussed. Finally, future research directions and prospects in the aluminum battery field are proposed.

新兴非水铝离子电池：挑战，现状和前景

铝离子电池（AIB）由于其高容量，低成本和铝丰富而被认为是锂离子技术的可行替代品。但是，水性体系的几个严重缺陷（钝化膜形成，析氢，阳极腐蚀等）阻碍了这些体系的大规模应用。因此，非水AIB在大规模电能存储方面显示出无与伦比的优势。但是，非水铝电池系统仍处于新生阶段，设计高容量，长循环寿命的AIB的各种技术和科学障碍至今仍未解决。此外，铝电池是一种复杂的设备，其能量密度由各种参数决定，其中大多数参数通常都被忽略，导致无法实现电池的最佳性能。这里的目的是讨论如何进一步开发可靠的非水AIB。首先，根据文献中的统计数据来回顾非水AIB的当前状态。分析了参数对能量密度的影响，总结了目前的现状和存在的问题。此外，全面讨论了有关构建可靠的非水AIB的可能解决方案和问题。最后，提出了铝电池领域的未来研究方向和前景。分析了参数对能量密度的影响，总结了目前的现状和存在的问题。此外，全面讨论了有关构建可靠的非水AIB的可能解决方案和问题。最后，提出了铝电池领域的未来研究方向和前景。分析了参数对能量密度的影响，总结了目前的现状和存在的问题。此外，全面讨论了有关构建可靠的非水AIB的可能解决方案和问题。最后，提出了铝电池领域的未来研究方向和前景。
