摘要： The current invention includes an additive manufactured electrode that may be used for a flow battery system. In some embodiments, the electrode may include a composite material and/or at least one flow channel to direct, or at least influence, flow of electrolyte. The flow channel can be formed onto a surface and/or within a body of the electrode, and may be used to generate fluid pathways that cause the electrolyte to flow in a certain manner. The composite material may include a rigid core and a flexible compressible outer layer that may improve reactions zones, enhance mechanical properties, and/or provide low-pressure paths for electrolyte to flow.

摘要： A method for producing electric power and regenerating an aqueous multi-electron oxidant (AMO) and a reducer in an energy storage cycle is provided. A discharge system includes a discharge unit, an acidification reactor, and a neutralization reactor. The acidification reactor converts an oxidant fluid including the AMO into an acidic oxidant fluid. The discharge unit generates electric power and a discharge fluid by transferring electrons from a positive electrode of an electrolyte-electrode assembly (EEA) to the AMO and from a reducer to a negative electrode of the EEA. The neutralization reactor neutralizes the discharge fluid to produce a neutral discharge fluid. The regeneration system splits an alkaline discharge fluid into a reducer and an intermediate oxidant in a splitting-disproportionation reactor and releases the reducer and a base, while producing the AMO by disproportionating the intermediate oxidant. The regenerated AMO and reducer are supplied to the discharge unit for power generation.
