摘要: Decoupled hydrogen and oxygen production were successfully embedded into an aqueous dual-electrolyte (acid–base) battery for simultaneous energy storage conversion. A three-electrode configuration was adopted, involving electrocatalytic hydrogen-evolving electrode as cathode, alkaline battery-type or capacitor-type anode shuttle, a charging-assisting electro-/photoelectrochemically catalyzing water oxidation. The conceptual not only synergistically outputs electricity chemical fuels with tremendous specific power densities, but also supports various approaches to be charged by pure solar-assisted electricity.
