Unprecedented VSe2/graphene nanocomposites are synthesized through a hydrothermal route. A large number of hexagonal VSe2 sheets anchored on the graphene sheets can be observed. The thicknesses and lengths of VSe2 sheets are controlled by graphene sheets. VSe2/graphene nanocomposite prepared with 15 mg graphite oxide (VSe2/G-15) exhibits the best electrochemical lithium storage properties such as charge/discharge capacities, cycle stability and rate capability when used as an anode material for lithium-ion batteries.
