A rocking-chair aqueous proton battery is assembled by using dipyridophenazine and indium hexacyanoferrate as the anode and cathode materials, respectively. The reversible amination of redox-active phenazine moieties in dipyridophenazine and fast intercalation–deintercalation of protons in hexacyanoferrate enable the aqueous proton battery to achieve a reversible specific capacity of 37 mA h g⁻¹ at 1 A g⁻¹, good cycling stability with 76.1% capacity retention over 3000 cycles and excellent rate capability.

威尼斯官网曹剑瑜-许娟团队最近在Chemical Communications上发表研究论文(DOI: 10.1039/d1cc01486b)。水系可充电电池通常以金属离子为电荷载体。然而，金属元素要么储量有限，要么开采成本相对较高。在所有离子中质子(氢离子)是最轻和最小的，在水溶液中具有最快的迁移速率，而且在地球上资源丰富。本论文设计了一种基于有机阳极和无机配合物阴极的水系可充电质子电池。阳极二吡啶吩嗪中氧化还原活性吡嗪单元的可逆胺化和阴极铟普鲁士蓝中质子的快速嵌入-脱嵌使该电池在1 Ag ^-1下可实现37 mAhg ^-1的可逆比容量，并展示了良好循环稳定性和出色的倍率性能。此项研究得到了国家自然科学基金和江苏省绿色催化重点实验室科学基金的资助。
