Facile synthesis of KVPO4F/reduced graphene oxide hybrid as a high-performance cathode material for potassium-ion batteries
文献摘要：
Potassium-ion batteries(PIBs)as a substitute for lithium-ion batteries have aroused widespread atten-tion and have been rapidly developed.In the positive electrode materials,polyanionic compound has a high working voltage and large reversible capacity on account of its distinct framework and the strong inducing effect of the anionic group.Herein,a KVPO4F/reduced graphene oxide(KVPF/rGO)hybrid was fabricated via a simple multi-step approach as the polyanionic cathode material for PIBs.Profiting from the small size of KVPF nanoparticles and their uniform distribution in the rGO framework,the as-synthesized KVPF/rGO hybrid manifests a large discharge capacity of 103.2 mAh g-1 with an outstanding energy density of 436.5 Wh kg-1.Through rGO decoration,the hybrid also demonstrates remarkable rate and cycling properties.By employing ex-situ X-ray diffraction(XRD)and X-ray photoelectron spec-troscopy(XPS)techniques,the potassium storage mechanism of KVPF was clearly revealed.The facile preparation procedure and superior properties endow it great application prospects in large-scale energy storage.
