Abstract: The present disclosure relates to a novel naphthalene diimide compound, an electrolyte solution for a redox flow battery containing the same, and a redox flow battery containing the same. The naphthalene diimide compound according to one embodiment exhibits a robust redox behavior, has high solubility in water, and has an advantage of being able to operate at neutral pH. In addition, since the naphthalene diimide compound according to one embodiment may improve the energy density by combining two electrons, it is useful as an additive for an electrolyte solution for a redox flow battery.

Abstract: Provided is an aqueous zinc battery including: a negative electrode including zinc; a positive electrode disposed to be opposite to the negative electrode; and an electrolyte solution including a zinc salt and an organic acid having two carboxylic acid groups, wherein the organic acid having two carboxylic acid groups has 2 to 4 carbon atoms between the two carboxylic acid groups.
It is intended to provide an electrolyte solution for an aqueous zinc battery and an aqueous zinc battery which prevent a passivation layer such as zinc hydroxide sulfate hydrate (ZHS, ZnSO4[Zn(OH)2]3·xH2O)) which deteriorates battery performance from being formed in a zinc electrode, maintain a pH of the electrolyte solution, promote uniform zinc deposition during a constant current cycle, and show improved battery cycle performance.
