▎ 摘　　要

We report, for the first time, a one-step, continuous synthesis of spherical lithium titanate (Li4Ti5O12, LTO)/graphene composites through direct aerosolization of a graphene oxide (GO) suspension mixed with Li and Ti precursors. The resulting crumpled graphene-sphere-supported LTO nanocrystals has a three-dimensional structure with a high electrical conductivity, a high surface area and good stability in electrolyte. The LTO/CG composite, as an anode in LIBs, exhibited excellent rate capability (for example, at a high current density of 5000 mA g(-1) it delivered 60% of the capacity obtained at 12.5 mA g(-1)) and an outstanding cycling performance (a capacity retention of 88% after 5000 cycles at 1,250 mA g(-1)). The one-step, continuous synthesis of the LTO/graphene composite offers a high-producing efficiency compared with conventional multi-step preparations, and can be generally applied for synthesizing lithium metal oxides/graphene (cathode or anode) materials for lithium-ion batteries.
