【 摘 要 】

In this work, Fe2O3was successfully synthesized by the hydrothermal process at low temperature. FeCl3.6H2O as precursor and variation of lysine as hydrolyzing agent were used to preparing Fe2O3. SEM images show that the morphology of Fe2O3is porous microsphere with sizes in the range of (1 to 5) μm in diameter. The as-prepared Fe2O3with the 2 M of lysine exhibits excellent cycling performance when used as the anode for lithium ion batteries, obtaining reversible discharge capacity of 172.33 mA•h•g-1at 0.5 C after 50 cycles. It is attributed to the unique structure of porous microspheres providing a large surface area which maintains good electronic contact between particles during charge-discharge process. This result demonstrates that Fe2O3porous microsphere has a high potential as anode material for application of lithium-ion battery.
