摘　　要：由于高安全的特性,水系二次电池被认为是未来大型储能的有效解决方案之一.然而,现有水系电池主要以含金属元素的无机化合物为电极活性材料,其在大型储能中的实际应用仍受到循环寿命、环境问题、原料成本或金属元素丰度的限制.相较于无机电极材料,部分有机电极材料具有原料丰富、结构丰富、可持续及环境友好等优点.此外,有机物材料分子内空间大,能够存储不同价态电荷,因此近年来被广泛关注.本文综述了课题组近期在有机物电极方面的研究进展,内容聚焦含羰基有机物通过C=O/C-O-的可逆转化存储单价金属阳离子(Li+, Na+)、双价金属阳离子(Zn2+)、质子(H+)所涉及的电化学过程,及其在水系锂、钠离子电池、水系锌离子电池、质子电池以及分步电解水中的应用.Aqueous batteries have been considered to be a competitive candidate for large-scale energy storage. However, most of aqueous batteries adopt inorganic electrode materials with metallic elements, which are based on the reversible insertion of metal ions, making their application being highly hindered by limited cycle life, environmental issue, high cost and low reserves. On the other hand, organic electrode materials offer the advantages of abundant reserves, tunable structures, renewability and environmental benignity. Furthermore, the wide internal space enables these organics to flexibly store various charge carriers. Organics have been investigated as the alternative to inorganic electrode materials. Herein, we review the progress in organic electrode materials reported by our group, focusing on the reaction chemistry of organics with carbonyls for storing monovalent ions(Li+, Na+), divalent ion(Zn2+) and proton(H+), and the corresponding application in the field of metal ion batteries, proton batteries and the water electrolysis as redox buffer electrodes.
