▎ 摘　　要

NOVELTY - A nanostructured lithium-niobium oxide/graphene electrode material is obtained by uniformly coating the nanostructured lithium-niobium oxide in the graphene sheet layer, where the graphene accounts for 5.3-32.8% of the total mass of the electrode material. USE - Nanostructured lithium-niobium oxide/graphene electrode material. ADVANTAGE - The nanostructured lithium-niobium oxide/graphene electrode material has high-rate characteristics and outstanding cycle stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing nanostructured lithium-niobium oxide/graphene electrode material (2) a nanostructured lithium-niobium oxide/graphene electrode material prepared by the method.
