Strategic Electrolyte Design to Address SolubilityCompetition between Redox-Active Molecules andSupporting Salts
The solubility of redox-active organic molecules (ROMs) in non-aqueous redox flow batteries (NRFBs) is a critical factor determining the energy density of the system. However, the scarcity of comprehensive solubility data has hindered electrolyte development. In this study, we systematically investigate the solubility behavior of ROMs in the presence of supporting salts to propose practical electrolyte formulations for NRFBs. Using automated high-throughput experimentation, we screen the solubility of 2,1,3-benzothiadiazole (BTZ) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in various organic solvents. Leveraging a Random Forest inference model, we identify a binary solvent mixture of mxylene and acetonitrile, which dissolves 3 M of both BTZ and LiTFSI—exceeding the previously reported 2 M limit in pure acetonitrile. This enhanced solubility is achieved by the inclusion of a LiTFSI-phobic yet BTZ-philic solvent, which counterbalances the solubility competition between BTZ and LiTFSI, with the latter favoring highly polar solvents. This work introduces a promising electrolyte design strategy for NRFBs and highlights the effectiveness of high-throughput screening combined with advanced data analysis for optimizing complex multi-component systems. Furthermore, it emphasizes the urgent need for more comprehensive solubility data to facilitate the development of practical NRFB electrolytes.
