A functional Na3V2(PO4)(2)O2F (NVPOF) cathode with a multi-component (Na3V(PO4)(2), V2O3, and reduced graphene oxide) surface coating is developed via a facile hydrothermal reaction followed by calcination, and exhibits high reversible capability, and long-term cycling stability even at a low temperature of -40 degrees C. It is demonstrated that the multi-component-coating layer can significantly accelerate the e(-)/Na+ transport and reduce the interfacial resistance at low temperature. This work provides a novel strategy to boost the kinetics and stability of electrode materials for low-temperature sodium ion batteries.
