摘      要：t In this paper,a facile strategy is proposed to controllably synthesize mesoporous Li_(4)Ti_(5)O_(12)/C nanocomposite embedded in graphene matrix as lithium-ion battery anode via the co-assembly of Li_(4)Ti_(5)O_(12)(LTO)precursor,GO,and phenolic resin.The obtained composites,which consists of a LTO core,a phenolic-resin-based carbon shell,and a porous frame constructed by rGO,can be denoted as LTO/C/rGO and presents a hierarchical structure.Owing to the advantages of the hierarchical structure,including a high surface area and a high electric conductivity,the mesoporous LTO/C/rGO composite exhibits a greatly improved rate capability as the anode material in contrast to the conventional LTO electrode.
