Enhanced Performance of TiO2/α-Fe2O3 Nanostructure as Anode Material for Lithium-ion Batteries

A novel lithium-ion anode material α-Fe 2 O 3 /TiO 2 is prepared by two-step hydrothermal method with pure titanium sheet, NaOH, and FeCl 3 solution. The nanocomposite material has been fully characterized by SEM, TEM EDX and XRD. The electrochemical performance of α-Fe 2 O 3 /TiO 2 nanocomposite as anode material in lithium ion batteries (LIB) are measured by battery test system and electrochemical workstation. The results demonstrate that the α-Fe 2 O 3 /TiO 2 nanocomposite is consisted of TiO 2 sheets and Fe 2 O 3 particles on the surface. The electrode exhibits excellent electrochemical performance with capacity retention of 638 mAh/g after 30 cycles at 33.5 mA/g.
