摘要

在 pH 值为 14 的水氧化还原液流电池的负电位电解质（电解液）中引入了一种从茜素中提取的水溶性蒽醌 3HAAQ，作为氧化还原活性材料。3HAAQ 的合成是通过曼尼希反应进行的，该反应大大提高了新化合物的溶解度，这是将其用于液流氧化还原电池的一个重要因素。这种液流电池与铁氰化钾/铁氰化铁正极电解质配对，开路电压为 1.24 V，在 40 mA cm-2 电流密度下可保持近 80% 的理论容量。

The Use of the Mannich Reaction toward Amino-Based Anthraquinone Applied in Aqueous Redox Flow Battery

A water-soluble anthraquinone derived from alizarin, 3HAAQ, is introduced as the redox-active material in a negative potential electrolyte (anolyte) for aqueous redox flow batteries operating at pH 14. The synthesis of 3HAAQ is carried out using the Mannich reaction, which significantly improves the solubility of the new compound, an important factor for its use in RFB. Pairing with potassium ferri/ferrocyanide positive electrolyte, this flow battery exhibits an open-circuit voltage of 1.24 V and maintains nearly 80% of the theoretical capacity at 40 mA cm⁻² current density.
