▎ 摘　　要

Anatase-TiO2/graphene nanosheets (TiO2/GNs) composite with 3D architecture was synthesized via an in-situ method. The honeycomb-like structure has a porous nature, high stability and abundant electron/lithium pathways. When the sample was used as an anode material for Li-ion battery, it showed an excellent electrochemistry performance with superior rate and cyclic performance. The capacity can keep at 184 mA h g(-1) at 50 C (16.5 A g(-1)) after 10000 cycles. While, when the rate increased to as high as 150 C (52.5 A g(-1)), the reversible capacity can still maintain at above 125 mA h g(-1). These results demonstrate the enormous potential of the nanocomposite has great potential applied in long-life LIBs.
