Hydrogen evolution reaction and Zn dendrite growth, originating from high water activity the adverse competition between electrochemical kinetics mass transfer, are main constraints for commercial applications of aqueous zinc-based batteries. Herein, a weak H-bond interface with suspension electrolyte is developed by adding TiO2 nanoparticles into electrolytes. Owing to strong polarity Ti-O bonds in TiO2, abundant hydroxyl functional groups formed TiO2[110] active surface environment, which can produce disrupting initial networks molecules, thereby accelerating transfer Zn2+ reducing activity. In consequence, Zn||Zn symmetrical cells display reversible plating/stripping behaviors Coulombic efficiency 99.7% over 700 cycles. Moreover, TiO2-based strategy also applicable other zinc salt systems exhibits fast behaviors. The enables long-term full cells, including Zn||PANI hybrid capacitors Zn||ZnVO

Herein, a chitin nanofiber membrane separator is developed tackle issues via simple, low‐cost, scalable strategy. The obtained exhibits abundant zincophilic functional groups, homogeneous nanopores, excellent mechanical properties, which facilitate desolvation hydrated 2+ ions, improve transference number, homogenize ion flux, simultaneously. Moreover, can also reduce deposition barrier, accelerate kinetics. Therefore, dendrites harmful effectively synchronously suppressed, enabling assembled ZIBs with an ultralong good rate capability.
