Amorphous amorphous nano antimony vanadium oxide/reduced graphene oxide composite material as well as preparation method and application thereof

The invention discloses an amorphous nano antimony vanadium oxide/reduced graphene oxide composite material as well as a preparation method and application thereof, belongs to the technical field of potassium ion batteries, and applies Sb2VO5 to the field of energy storage for the first time to solve the problems in the prior art. A solvothermal and low-temperature calcination two-step method is adopted to adjust and synthesize the reduced graphene oxide coated amorphous amorphous nano antimony vanadium oxide composite negative electrode material (namely an amorphous amorphous nano antimony vanadium oxide/reduced graphene oxide composite material), so that the conductivity of the composite material is improved; the electron/ion transmission rate and electrochemical reaction kinetics of active substances are improved, ion storage sites and channels are increased, and the potassium ion battery negative electrode material with high capacity and long cycle stability is successfully prepared. 本发明公开了无定形非晶纳米锑钒氧化物/还原
