Graphene modified LiVPO4F/C nanocomposite has been firstly investigated as cathode material for lithium-ion batteries. The LiVPO4F/C nanocrystals embedded on reduced graphene oxide sheets are synthesized via a sol–gel method. The obtained sample of graphene modified LiVPO4F/C is studied comparatively with LiVPO4F/C by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron...
Nd-doped Li 3 V 2−x Nd x (PO 4 ) 3 /C (x=0, 0.01, 0.02, 0.04, 0.06 and 0.08) cathode materials are successfully and fast synthesized by a microwave solid-state route. The effects of Nd-doping on the structure and electrochemical properties of Li 3 V 2 (PO 4 ) 3 /C are investigated. Compared with the X-ray diffraction (XRD) pattern...
