▎ 摘　　要

NOVELTY - A lithium titanate composite material comprises lithium titanate nano paticles and graphene, where the lithium titanate nano particles comprises lithium-titanate-oxide component dispersed between the graphene. USE - Lithium titanate composite material for use in lithium battery and super capacitor. ADVANTAGE - The composite material has high electrical conductivity and excellent cyclic performance. DETAILED DESCRIPTION - A lithium titanate composite material comprises lithium titanate nano paticles and graphene, where the lithium titanate nano particles comprises lithium-titanate-oxide (Li4Ti5O12) component dispersed between the graphene. An INDEPENDENT CLAIM is also included for a method for preparing lithium titanate composite material, which involves mixing 100 parts titanium dioxide and 37-115 parts lithium source to obtain mixture, followed by smashing and sieving to prepare lithium titanate composite material.
