▎ 摘　　要

NOVELTY - A sodium vanadium fluorophosphate/reduced graphene oxide composite material comprises a layered reduced graphene oxide as a substrate and sodium vanadium fluorophosphate particles which are uniformly attached to a surface of graphene. USE - Sodium vanadium fluorophosphate/reduced graphene oxide composite material is used as anode material for sodium ion battery and zinc ion battery (all claimed). ADVANTAGE - The sodium vanadium fluorophosphate/reduced graphene oxide composite material comprises graphene which efficiently improves electroconductivity of sodium vanadium fluorophosphate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the sodium vanadium fluorophosphate/reduced graphene oxide composite material, which involves using vanadium acetylacetonate, absolute ethanol, sodium dihydrogen phosphate, sodium fluoride, deionized water, and graphene oxide solution.
