▎ 摘　　要

NOVELTY - A lithium titanate-graphene nano composite electrode material is a composite material prepared from lithium titanate and grapheme through hydrothermal reaction. The molar ratio of lithium ions to graphene is 1:1-4:1. The molar ratio of lithium ions to deionized water in the lithium titanate is 1:1-5:1. USE - Lithium titanate-graphene nano composite electrode material is used for power lithium-ion battery. ADVANTAGE - The lithium titanate-graphene nano composite electrode material is efficiently prepared with high specific capacity, stability and rate capability, by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of lithium titanate-graphene nano composite electrode material.
