1,10-Phenanthroline-5,6-dione (phendione)-based transition-metal complexes are known for their use in pharmacological and catalysis applications. However, their application in electrochemical energy storage has not been investigated thus far. Herein, the feasibility of employing phendione-transition-metal complexes was investigated for electrochemical charge storage by taking advantage of the reversible redox activity of both carbonyl groups and transition metal center, contributing to augmented charge storage. Interestingly, the chemistry of the counter ion in the studied complexes effectively tuned the solubility and improved the cycling stability. Although further studies are required to limit the solubility and active-species shuttle, this study explores the bottlenecks of phendione-transition-metal complexes as electrode materials for solid-electrode-format batteries.

具有双极性氧化还原活性的锂电池的苯甲醛过渡金属配合物。

基于1,10-菲咯啉-5,6-二酮（苯二酮）的过渡金属配合物因其在药理和催化应用中的用途而闻名。然而，到目前为止，还没有研究它们在电化学能量存储中的应用。在此，通过利用羰基和过渡金属中心的可逆氧化还原活性，研究了将苯二酮-过渡金属配合物用于电化学电荷存储的可行性，从而有助于电荷存储的增加。有趣的是，所研究的配合物中抗衡离子的化学性质有效地调节了溶解度并改善了循环稳定性。尽管需要进行进一步的研究以限制溶解度和活性物质穿梭，
