Abstract

TiO2 anodes have attracted great attention due to their good cycling stability for lithium ion batteries and sodium ion batteries (LIBs and SIBs). Unfortunately, the low specific capacity and poor conductivity limit their practical application. The mixed phase TiO2 nanobelt (anatase and TiO2-B) based Co9S8 composites have been synthesized via the solvothermal reaction and subsequent calcination. During the formation process of hierarchical composites, glucose between TiO2 nanobelts and Co9S8 serves as a linker to increase the nucleation and growth of sulfides on the surface of TiO2 nanobelts. As anode materials for LIBs and SIBs, the composites combine the advantages of TiO2 nanobelts with those of Co9S8 nanomaterials. The reversible specific capacity of TiO2 nanobelt@Co9S8 composites is up to 889 and 387 mAh·g−1 at 0.1 A·g−1 after 100 cycles, respectively. The cooperation of excellent cycling stability of TiO2 nanobelts and high capacities of Co9S8 nanoparticles leads to the good electrochemical performances of TiO2 nanobelt@Co9S8 composites.
