Aggregation and Capacity Limiting Effects in Anthraquinone-Based Flow Battery Negolytes

Alexandros Pasadakis-Kavounis,

Abstract: Anthraquinone-based molecules are promising electroactive materials suitable for use in aqueous organic flow batteries. At high concentrations in aqueous solutions, the well-known negolyte molecule anthraquinone disulfonic acid (AQDS) molecule has been observed to aggregate under near-neutral and acidic conditions. Aggregation has been hypothesized to be directly linked to observed concurrent capacity reduction. In this study, we investigated three different water-soluble anthraquinones in electrolytes of vary… Show more
