1. An ultra-high stability phenazine-based electrolyte for an alkaline aqueous organic redox flow battery, comprising a polyhydroxy cyclic supramolecule, a phenazine-based organic compound, and an alkaline aqueous solution,
wherein the polyhydroxy cyclic supramolecule is a cyclodextrin or a derivative of the cyclodextrin; and
in the ultra-high stability phenazine-based electrolyte, a concentration of the phenazine-based organic compound is 0.05 mol/L to 0.3 mol/L, a concentration of the polyhydroxy cyclic supramolecule is 0.01 mol/L to 0.1 mol/L, and a concentration ratio of the phenazine-based organic compound to the polyhydroxy cyclic supramolecule is 1:(0.1-0.5).
