The second precursor solution includes AX?M2(CN)Z?, where M1 and M2 are from a first group of metals and A is from a second group of metals including alkali or alkaline earth metals. In response to stirring the first and second precursors, MCM particles are formed with the formula AXM1NM2M(CN)Z.d[H2O]ZEO.e[H2O]BND, in solution. In response to aging in the secondary reactor, the size of the MCM particles is increases. The aged MCM particles in solution are then transferred to a separation tank, where the aged MCM particles are filtered from the solution and collected. The solution reclaimed from the separation tank back is added back into the main reactor.

    Abstract: RFBs having solid hybrid electrodes can address at least the problems of active material consumption, electrode passivation, and metal electrode dendrite growth that can be characteristic of traditional batteries, especially those operating at high current densities. The RFBs each have a first half cell containing a first redox couple dissolved in a solution or contained in a suspension. The solution or suspension can flow from a reservoir to the first half cell. A second half cell contains the solid hybrid electrode, which has a first electrode connected to a second electrode, thereby resulting in an equipotential between the first and second electrodes. The first and second half cells are separated by a separator or membrane.
