Electrophoretically deposited α-Fe2O3 and TiO2 composite anchored on rGO with excellent cycle performance as anode for lithium ion batteries

The results revealed that α-Fe2O3/TiO2/rGO (in this article denoted as FTGO) exhibited the specific discharge capacity of 790 mAh·g−1 after 150 cycles at the current density 100 mA·g−1. The improved electrochemical properties were obtained due to rGO uniform dispersion within inter-space of α-Fe2O3 and TiO2 as well as synergic effect between both metal and graphene oxides. Additionally, rGO not only has excellent electron conductivity, but also can alleviate the solid-electrolyte interphase film formation. Prepared composite exhibit excellent cycle performance, coulombic efficiency (66%) and rate capability. Therefore, FTGO ternary structure material has perspective application as lithium ion battery anode in comparison with a α-Fe2O3/rGO and TiO2/rGO composites. The results showed obtained composite is a promising anode material for high energy and long cycle life lithium ion batteries.
