Abstract
Abstract Organic p‐type cathode materials with high redox potentials and fast kinetics have captured widespread attention in propelling Zn‐organic batteries (ZOBs). However, their anion‐accessible capacity is insufficient due to single electron reaction and/or high energy barrier of each redox‐active unit. Here, we design two‐electron‐donating p‐type organic chalcogen small molecules (phenoxazine (PO), phenothiazine (PS), and phenoselenazine (PSe)) with tuned charge distributions and electron transfer behaviors as cathode materials for ZOBs. With the decrease of chalcogenide electronegativity (O > S > Se), PSe liberates the strongest coordination activity, efficient electron delocalization, and charge…
