摘要： Titanium complexes containing at least one catecholate ligand can be desirable active materials for flow batteries and other electrochemical energy storage systems. Such complexes can be formed through reacting a catechol compound with a titanium reagent in an organic solvent, removing a byproduct species, and then obtaining an aqueous phase containing a salt form of the titanium catechol complex, particularly an alkali metal salt form. More specifically, the methods can include: forming a catechol solution containing a catechol compound and an organic solvent, contacting a titanium reagent with the catechol solution to form a reaction mixture, reacting the titanium reagent with the catechol compound to form an intermediate titanium catechol complex and a byproduct species, separating the byproduct species, and combining an alkaline aqueous solution containing a base with the intermediate titanium catechol complex to produce a salt form titanium catechol complex at least partially dissolved in an aqueous phase.

摘要： Titanium catecholate complexes can be desirable active materials for flow batteries and other electrochemical energy storage systems, particularly when incorporated in aqueous electrolyte solutions. It can be desirable to avoid introducing even traces of certain organic solvents into aqueous electrolyte solutions. Neat methods for synthesizing titanium catecholate complexes can help avoid the unwanted introduction of trace organic solvents into aqueous electrolyte solutions and also provide further advantages. Methods for synthesizing titanium catecholate complexes can include: combining a catechol compound and a titanium reagent in an absence of solvent to produce a reaction mixture, and reacting the titanium reagent with the catechol compound in a neat state to form a titanium catecholate complex containing at least one catecholate ligand. The titanium catecholate complex can be further reacted with a base to produce a salt form titanium catecholate complex, which can be present in an aqueous phase.

摘要： Electrolyte solutions for flow batteries and other electrochemical systems can contain an active material capable of transferring more than one electron per oxidation-reduction cycle. Such active materials can include coordination compounds containing a metal center and at least one redox non-innocent ligand. Accordingly, flow batteries can include a first half-cell having a first electrolyte solution therein, where the first electrolyte solution contains a coordination compound having at least one redox non-innocent ligand coordinated to a metal center. Particular redox non-innocent ligands can include those bearing a quinone functional group, such as substituted catecholates bearing a quinone functional group. Some active materials can include compositions containing a coordination compound having at least one redox non-innocent ligand coordinated to a metal center, where the at least one redox non-innocent ligand is a substituted catecholate or a salt thereof bearing a quinone functional group.

摘要： Solids can sometimes form in one or more electrolyte solutions during operation of flow batteries and related electrochemical systems. Over time, the solids can accumulate and compromise the integrity of flow pathways and other various flow battery components. Flow batteries configured for mitigating solids therein can include an autonomous solids separator, such as a lamella clarifier. Such flow batteries can include a first half-cell containing a first electrolyte solution, a second half-cell containing a second electrolyte solution, a first flow loop configured to circulate the first electrolyte solution through the first half-cell, a second flow loop configured to circulate the second electrolyte solution through the second half-cell, and at least one lamella clarifier in fluid communication with at least one of the first half-cell and the second half-cell. A hydrocyclone can be used as an alternative to a lamella clarifier in some instances.
