Electrochemical investigation of neodymium doped vanadium pentoxide anchored on reduced graphene oxide nanocomposites for hybrid symmetric capacitor devices

Facile synthesis of V4+-doped and graphene-decorated V2O5/biomass carbon nanocomposite using graphene quantum dots for supercapacitors with wide voltage window and high energy density

“…The fourth approach is to dope other metals into V 2 O 5 crystals. 25 Senthil Kumar et al synthesized a Ru-doped V 2 O 5 /graphene composite via the sol–gel route. 26 Their results showed that the combination of graphene and Ru with V 2 O 5 can enhance the surface area and reversible pseudo capacitance and decrease the ion diffusion length.…”
