Rechargeable aluminum-ion (Al-ion) batteries have been highlighted as a promising candidate for large-scale energy storage due to the abundant aluminum reserves, low cost, high intrinsic safety, and high theoretical energy density. However, the strong Coulombic interaction between the high charge density Al3+ and electrode host lattices leads to poor kinetics and insufficient cycle life in Al-ion batteries with inorganic electrodes. In contrast, organic electrode materials exhibit the advantages of designable molecular structure, flexible framework, coordinated energy storage chemistry, and resource sustainability. Nevertheless, organic materials encounter inherently high solubility, low active center utilization, and low electrical conductivity. Herein, the recent advances in developing organic positive electrode materials for Al-ion batteries is reviewed, and the charge storage mechanisms and electrochemical performances of different types of organic materials are systematically summarized. This review also discusses design strategies to improve specific capacity, operating voltage, cycle life, and rate capability of organic positive electrodes for Al-ion batteries. Finally, the challenges and research outlook toward high performance Al/organic batteries are presented.

可充电铝离子电池用有机正极材料开发的最新进展

可充电铝离子(Al-ion)电池因其丰富的铝储量、低成本、高本质安全性和高理论能量密度而成为大规模储能的有希望的候选者。然而,高电荷密度Al 3+之间的强库仑相互作用和电极主体晶格导致具有无机电极的铝离子电池的动力学不良和循环寿命不足。相比之下,有机电极材料具有可设计的分子结构、灵活的框架、协调的储能化学和资源可持续性等优点。然而,有机材料具有固有的高溶解度、低活性中心利用率和低电导率。本文综述了近年来开发用于铝离子电池的有机正极材料的进展,系统总结了不同类型有机材料的电荷存储机制和电化学性能。本综述还讨论了提高比容量、工作电压、循环寿命、铝离子电池有机正极的倍率性能和倍率性能。最后,介绍了高性能铝/有机电池面临的挑战和研究前景。
