Insights into the enhanced electrochemical performance and energy storage mechanism of a manganese vanadate cathode for rechargeable aqueous zinc ion batteries

Abstract

An N-doped reduced graphene oxide sheet wrapped MnV₂O₆ nanrod composite was designed and prepared by a co-precipitation reaction and subsequent calcination method, which delivered stable reversible capacity, low charge transfer resistance and high diffusion coefficients during the Zn²⁺ insertion and extraction processes.
