Benefiting from the merits of low cost, nonflammability, and high operational safety, aqueous rechargeable batteries have emerged as promising candidates for large-scale energy-storage applications. Among various metal-ion/non-metallic charge carriers, the proton (H⁺) as a charge carrier possesses numerous unique properties such as fast proton diffusion dynamics, a low molar mass, and a small hydrated ion radius, which endow aqueous proton batteries (APBs) with a salient rate capability, a long-term life span, and an excellent low-temperature electrochemical performance. In addition, redox-active organic molecules, with the advantages of structural diversity, rich proton-storage sites, and abundant resources, are considered attractive electrode materials for APBs. However, the charge-storage and transport mechanisms of organic electrodes in APBs are still in their infancy. Therefore, finding suitable electrode materials and uncovering the H⁺-storage mechanisms are significant for the application of organic materials in APBs. Herein, the latest research progress on organic materials, such as small molecules and polymers for APBs, is reviewed. Furthermore, a comprehensive summary and evaluation of APBs employing organic electrodes as anode and/or cathode is provided, especially regarding their low-temperature and high-power performances, along with systematic discussions for guiding the rational design and the construction of APBs based on organic electrodes.

使用质子作为电荷载体的水性有机电池

得益于低成本、不易燃和高操作安全性等优点，水系可充电电池已成为大规模储能应用的有希望的候选者。在各种金属离子/非金属载流子中，质子（H ⁺）作为载流子具有许多独特的性质，例如快速的质子扩散动力学、低摩尔质量和小水合离子半径，这赋予了水质子电池（APB）具有显着的倍率性能、长寿命和优异的低温电化学性能。此外，氧化还原活性有机分子具有结构多样性、丰富的质子存储位点和丰富的资源等优点，被认为是有吸引力的APB电极材料。然而，APB 中有机电极的电荷存储和传输机制仍处于起步阶段。因此，寻找合适的电极材料并揭示H ⁺存储机制对于有机材料在APBs中的应用具有重要意义。本文综述了用于APB的小分子和聚合物等有机材料的最新研究进展。此外，对采用有机电极作为阳极和/或阴极的APBs，特别是其低温和高功率性能进行了全面的总结和评估，并进行了系统的讨论，以指导基于有机电极的APBs的合理设计和构建。电极。
