Molecular Engineering Empowers Phenanthraquinone Organic Cathodes with Exceptional Cycling Stability for Lithium- and Aqueous Zinc-Ion Batteries.

ABSTRACT: Organic electrode materials have garnered great attention in recent years, owing to their resource sustainability, structural diversity, and superior compatibility with various ionic species. Among them, quinone-based compounds have attracted particular interest. Notably, compared with para-quinone analogs (e.g., anthraquinone), ortho-quinone-based electrode materials (e.g., phenanthraquinone) demonstrate higher redox potential, which contributes to achieving higher energy density in battery applications. However, their practical applications have been limited by severe solubility in electrolytes, resulting in poor cycle performance. To improve it, two novel phenanthraquinone-derived molecules, 1,4-bis(9,10-phenanthraquinonyl)benzene (BPQB) and 1,3,5-tri(9,10-phenanthraquinonyl)benzene (TP
