▎ 摘　　要

3D Li2ZnTi3O8 conductive network co-modified with graphene nanosheets and carbon nanotubes is successfully synthesized by a two-step reaction. The conductive structure is largely advantageous to its electrochemical performance for Li2ZnTi3O8. When cycled for 550 cycles, 81.3% and 84.2% of the capacities for the 2nd cycle is kept at 1 and 2 A g(-1) , respectively. After 300 cycles, 175.5, 153.3 and 144.9 mAh g(-1) are obtained at 3, 4 and 5 A g(-1), respectively. The excellent cyclic performance and the large specific capacities at high rate are due to the good conductive network of the Li2ZnTi3O8 active particles, large pore volume, small particle size, and good kinetics behavior.
