Abstract Capacitive carbon cathodes deliver great potential for zinc‐ion hybrid capacitors (ZHCs) due to their resource abundance and structural versatility. However, the dimension mismatch between micropores of carbons hydrated Zn 2+ ions often results in unsatisfactory charge storage capability. Here well‐arranged heterodiatomic superstructures are reported with compatible pore dimensions activating ions, initiated by supramolecular self‐assembly 1,3,5‐triazine‐2,4,6‐triamine cyanuric acid via in‐plane hydrogen‐bonds out‐of‐plane π – interactions. Flower‐shaped expose more surface‐active motifs, continuous charge‐transport routes, importantly, well‐developed pores. The primary subnanopores 0.82 nm size‐exclusively accessible solvated (0.86 nm) maximize spatial storage, while rich mesopores (1–3 allow high‐kinetics ion migration a low activation energy. Such favorable superstructure contribute all‐round performance improvement ZHCs, including high energy density (158 Wh kg −1 ), fast‐charging ability (50 A g excellent cyclic lifespan (100 000 cycles). An anion−cation mechanism is elucidated cathode, which entails alternate physical uptake /CF 3 SO − at electroactive pores bipedal chemical binding electronegative carbonyl/pyridine motifs. This work expands design landscape advanced storage.

Abstract Recently, aqueous Zn−X (X=S, Se, Te, I 2 , Br ) batteries (ZXBs) have attracted extensive attention in large‐scale energy storage techniques due to their ultrahigh theoretical capacity and environmental friendliness. To date, despite tremendous research efforts, achieving high density ZXBs remains challenging requires a synergy of multiple factors including cathode materials, reaction mechanisms, electrodes electrolytes. In this review, we comprehensively summarize the various conversion mechanism zinc‐sulfur (Zn−S) batteries, zinc‐selenium (Zn−Se) zinc‐tellurium (Zn−Te) zinc‐iodine (Zn−I zinc‐bromine (Zn−Br along with recent important progress design electrolyte advanced (S, materials. Additionally, investigate fundamental questions highlight correlation between battery performance. This review will stimulate an in‐deep understanding guide batteries.
