Abstract Organosulfides are considered promising cathode materials for zinc batteries due to their merits of high‐density active sites and multielectron reactions, but often suffer from sluggish kinetics limited electrochemical stability. Here organic iodide‐catalyzed is reported stabilized multielectron‐redox bis(dimethylthiocarbamyl) sulfide (BS) superior zinc‐organosulfide batteries. Activated by 2e − I /I 3 conversion in 1‐methyl‐3‐propylimidazolium iodide (MPII)‐modulated electrolyte, the electron‐deficient structure BS can stretch electron cloud two adjacent C═S bonds form bipedal C─S bonds, affording high‐kinetics stable Zn─S storage electrochemistry. This allows high accessibility zincophilic dual C = S with a low activation energy, stabilizes fulfil anti‐dissolution electrolyte. Consequently, Zn||BS battery 4e conversion‐coordination harvests high‐rate capacities (452 mAh g −1 at 1 A ; 255 10 ), energy density (312 Wh kg ) ultralong life (30000 cycles), becoming state‐of‐the‐art all‐round metrics. work constitutes significant advance developing high‐redox‐activity organosulfide stand good starting point advanced

Abstract Designing multiple redox sites in electroactive organic cathodes that allow more electron transfer is a permanent target for energy storage. Here, six‐electron zinc–organic batteries are reported accessed by duodecuple H‐bonded NH 4 + storage N‐heterocyclic dipyrazino[2,3‐f:2′,3′‐h]quinoxaline‐2,3,6,7,10,11‐hexacarbonitrile (DQH) cathode. DQH features an extended π‐conjugated aromatic planarity enriched with super delocalization routes and dodecahedral‐active imine/cyano motifs, achieving high capacity up to 385 mAh g −1 at 0.5 A . Besides, cathode redox‐exclusively couples small‐hydration‐size low‐desolvation‐energy‐barrier ions (0.33 nm 0.19 eV vs 0.86 0.36 of Zn 2+ ) via flexible H‐bonding interactions. topo‐coordination enables anti‐dissolution aqueous electrolytes avoid common decay small molecules, solves the instability low interfacial reaction kinetics issues caused rigidly sluggishly repeated insertion ions. This gives battery high‐rate ability (30 lifespan 000 cycles 10 ).
