Boosted Charge Transfer in Twinborn ��-(Mn2O3-MnO2) Heterostructures: Toward High-Rate and Ultralong-Life Zinc-Ion Batteries

Journal Article


Abstract


  • Aqueous ZIBs are one of the most promising next-generation rechargeable batteries because of the high capacity, high hydrogen evolution overpotential, and chemically stable reversible plating/stripping of the zinc electrode in the mild aqueous electrolyte. However, there are limited cathode materials that can store Zn2+ reversibly with superior cycling and rate capability. Herein, hierarchically porous nanorods composed of twinborn ��-(Mn2O3-MnO2) heterostructures are proposed as a robust cathode for Zn storage. Thanks to the hierarchically porous nanorod morphology and the abundant interface of the heterostructures involving a built-in electric field, the as-obtained twinborn ��-(Mn2O3-MnO2) electrode delivers a high capacity of 170 mA h g-1 for 2000 cycles at 500 mA g-1 and shows an excellent rate capability of up to 1.5 A g-1 with a capacity of 124 mA h g-1. The inspiring results achieved exhibit the enormous potential of the high-performance heterostructure cathode for fast and stable ZIBs.
