Core-shell Li₃V₂(PO₄)₃@C nanostructured composites were prepared via a sol-gel route followed byhydrothermal treatment. XRD patterns showed that Li₃V₂(PO₄)₃ has a monoclinic structure with space groupP2₁/n. TEM images exhibited that Li₃V₂(PO₄)₃ particles are encapsulated with a carbon shell ~10 nm inthickness. Compared with pure Li₃V₂(PO₄)₃, core-shell Li₃V₂(PO₄)₃@C composites presented enhancedelectrochemical Li ion intercalation performances. Cyclic voltammetry and electrochemical impedancespectroscopy disclosed that carbon shells improved Li ion diffusion and electrical conductance significantlyand also retarded formation of solid electrolyte interphase film of Li₃V₂(PO₄)₃ cathode materials.
