NOVELTY - Preparing lithium titanate/graphene nano-composite material involves dissolving oxidized graphite into deionized water, ultrasonic dispersing to obtain oxidized graphite sol. The obtained oxidized graphite sol is stirred, and added cyclodextrin solution to obtain beta -cyclodextrin-oxidized graphite supramolecular sol-gel A. The titanium dioxide suspension is added into sol-gel A, and added ammonia to adjusted pH, irradiated with ultraviolet light to obtain titanium dioxide beta -cyclodextrin-oxidized graphite supramolecular system sol. USE - Method for preparing lithium titanate/graphene nano-composite material (claimed). ADVANTAGE - The method enables to prepare lithium titanate/graphene nano-composite material which has improves conductive efficiency of the lithium titanate. DETAILED DESCRIPTION - Preparing lithium titanate/graphene nano-composite material involves dissolving oxidized graphite into deionized water, ultrasonic dispersing to obtain oxidized graphite sol. The obtained oxidized graphite sol is stirred, and added cyclodextrin solution to obtain beta -cyclodextrin-oxidized graphite supramolecular sol-gel A. The titanium dioxide suspension is added into sol-gel A, and added ammonia to adjusted pH, irradiated with ultraviolet light to obtain titanium dioxide beta -cyclodextrin-oxidized graphite supramolecular system sol, and obtain sol is centrifuged to obtain concentrated liquid and freeze-dried to obtain solid B. The lithium source and resulted solid B are transferred to ball mill for ball milling, resulted powder is calcined in inert gas atmosphere to obtain final product.
