Proton Insertion Chemistry of a Zinc-Organic Battery
Tie, Liu, Deng, Zhao, Niu (2020) Proton Insertion Chemistry of a Zinc-Organic Battery Angew Chem Int Ed Engl (IF: -1) 59(12) 4920-4924Abstract
Proton storage in rechargeable aqueous zinc-ion batteries (ZIBs) is attracting extensive attention owing to the fast kinetics of H+ insertion/extraction. However, it has not been achieved in organic materials-based ZIBs with a mild electrolyte. Now, aqueous ZIBs based on diquinoxalino [2,3-a:2',3'-c] phenazine (HATN) in a mild electrolyte are developed. Electrochemical and structural analysis confirm for the first time that such Zn-HATN batteries experience a H+ uptake/removal behavior with highly reversible structural evolution of HATN. The H+ uptake/removal endows the Zn-HATN batteries with enhanced electrochemical performance. Proton insertion chemistry will broaden the horizons of aqueous Zn-organic batteries and open up new opportunities to construct high-performance ZIBs.© 2020 Wiley-VCH Verlag GmbH & Co.
