Preparation of graphene/TiO2 anode materials for lithium-ion batteries by a novel precipitation method

Abstract This paper reports a large-scale production route for graphene/TiO 2 nanocomposites using water-based in situ precipitation method. In this method, freshly prepared graphene oxides/TiO 2 obtained by precipitating Ti(SO 4 ) 2 with NH 3 H 2 O was subjected to heat treatment in the presence of N 2 , which resulted in the formation of graphene/TiO 2 nanocomposites. Graphene/TiO 2 composites prepared by our method were found to be suitable as anode materials for lithium ion batteries because of its stable cycling performance and high capacity.
