Organic small molecules as high-capacity cathodes for Zn-organic batteries have inspired numerous interests, but are trapped by their easy-dissolution in electrolytes. Here we knit ultrastable lock-and-key hydrogen-bonding networks between 2, 7-dinitropyrene-4, 5, 9, 10-tetraone (DNPT) and NH4+ charge carrier. DNPT with octuple-active carbonyl/nitro centers (H-bond acceptor) redox-exclusively accessible flexible tetrahedral ions donator) exclude larger rigid Zn2+ , due to a lower activation energy (0.14 vs. 0.31 eV). coordinated H-bonding chemistry conquers the stability barrier of electrolyte, gives fast diffusion kinetics non-metallic A stable two-step 4e- coordination cathode harvests high capacity (320 mAh g-1 ), high-rate capability (50 ) an ultralong life (60,000 cycles).
