Exploring V10O24⋅12H2O@Reduced graphene oxide composite as cathode material for aqueous Zn-ion batteries

Abstract

The Zn-ion battery has gained attention in the energy market due to its high theoretical specific capacity, low cost, and stability. However, its large radius poses challenges for diffusion during charging and discharging. To address diffusion issues, a cathode material with a layer-like structure and increased interlayer distance is crucial. A synthesized cathode material, V10O24⋅12H2O@ Reduced Graphene Oxide (rGO), exhibited layered structure and prevented cathode dissolution while providing structural stability. It provides high columbic efficiency and high specific capacity.
