To overcome limited information on organic cathode materials for lithium-ion batteries, we studied the electrochemical redox properties of pyrenetetrone and its nitrogen-doped derivatives. Three primary conclusions are highlighted from this study. First, the redox potential increases as the number of electron-withdrawing nitrogen dopants increases.

- The study focuses on evaluating the redox properties of fluoranil derivatives as organic cathodes in sodium-ion batteries using density functional theory modeling.
- The research reveals that while bulky trifluoromethyl groups increase redox potential, they lower charge capacity, indicating their negative impact on battery performance.
- Additionally, fluoranil shows better redox properties than its hydrogenated counterpart, benzoquinone, and performance is influenced by structural, electronic characteristics, and solvation energy, providing insights for future organic cathode designs.
