摘要：

A novel lithium-ion anode material alpha-Fe2O3/TiO2 is prepared by two-step hydrothermal method with pure titanium sheet, NaOH, and FeCl3 solution. The nanocomposite material has been fully characterized by SEM, TEM EDX and XRD. The electrochemical performance of alpha-Fe2O3/TiO2 nanocomposite as anode material in lithium ion batteries (LIB) are measured by battery test system and electrochemical workstation. The results demonstrate that the alpha-Fe2O3/TiO2 nanocomposite is consisted of TiO2 sheets and Fe2O3 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.
