    • A method is provided for synthesizing a metal-doped transition metal hexacyanoferrate (TMHCF) battery electrode. The method prepares a first solution of A x Fe(CN) 6 and Fe(CN) 6 , where A cations may be alkali or alkaline-earth cations. The method adds the first solution to a second solution containing M-ions and M`-ions. M is a transition metal, and M` is a metal dopant. Subsequent to stirring, the mixture is precipitated to form A x M c M` d Fe z (CN) n .mH 2 O particles. The A x M c M` d Fe z (CN) n .mH 2 O particles have a framework and interstitial spaces in the framework, where M and M` occupy positions in the framework. Alternatively, the method prepares A a A` b M y Fe z (CN) n .mH 2 O particles. A and A` occupy interstitial spaces in the A a A` b M y Fe z (CN) n .mH 2 O particle framework. A metal-doped TMHCF electrode is also provided.

    • Electrolyte solutions for flow batteries and other electrochemical systems can contain a dissolved iron hexacyanide complex as an active material. Alkaline buffering can be desirable in such electrolyte solutions to promote stability of the active material. However, the buffer material can undesirably decrease solubility of the iron hexacyanide complex to unacceptable levels in some instances. Compositions with increased concentrations of iron hexacyanide can include an aqueous solution containing a dissolved iron hexacyanide complex, and a solid buffer material in contact with the aqueous solution. The solid buffer material is present at an amount greater than that needed to produce a saturation concentration of the solid buffer material in the aqueous solution. Flow batteries and other electrochemical systems can contain the compositions as an electrolyte solution. Electrolyte solutions containing active materials other than an iron hexacyanide complex can also be stabilized by using an appropriate solid buffer material.
    • 用于流动电池和其他电化学系统的电解液可以含有溶解的六氰化锡铁配合物作为活性材料。 在这种电解质溶液中碱性缓冲是可取的,以促进活性材料的稳定性。 然而,缓冲材料在某些情况下可能不期望地降低六氰化铁络合物的溶解度至不可接受的水平。 具有增加浓度的六氰化铁的组合物可以包括含有溶解的六氰化铁的络合物的水溶液和与该水溶液接触的固体缓冲材料。 固体缓冲材料的存在量大于在水溶液中产生固体缓冲材料的饱和浓度所需的量。 流动电池和其他电化学系统可以包含作为电解质溶液的组合物。 含有除六氰酸铁配合物以外的活性物质的电解质溶液也可以通过使用合适的固体缓冲材料来稳定。
