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.
