  • Heteroaryl-pyridinium compound and redox flow battery comprising the same
    Patent number: 12643893
    Abstract: Provided are a heteroaryl-pyridinium compound and a redox flow battery including the same. The redox flow battery includes a positive electrode cell including a positive electrode and a posolyte solution; a negative electrode cell including a negative electrode and a negolyte solution; and a separator disposed between the positive electrode cell and the negative electrode cell. The negolyte solution is the electrolyte solution for a redox flow battery.

  • NAPHTHALENE DIIMIDE COMPOUND AND REDOX FLOW BATTERY CONTAINING THE SAME
    Publication number: 20240243327
    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.
