Abstract

A tetragonal NaVPO₄F coated with reduced graphene oxide (rGO) manifests an outstanding high-rate capability of 90.6 mA h g⁻¹ at 10C and a stable capacity of 41.9 mA h g⁻¹ after 4000 cycles at 30C owing to the enhanced electronic conductivity and improved Zn²⁺ diffusion capability from the rGO coating.
