Abstract

The layered cathode materials of LiV3O8 were successfully prepared for the lithium rechargeable battery via a wet-chemistry synthesis method. The as-synthesized materials were characterized by XRD (powder X-ray diffraction), SEM (scanning electron microscope) and galvanostatic charge-discharge test. The results indicate that this soft-synthesis technique offers reduced calcinations temperature, preferred surface morphology and better electrochemical performance. Among the thus-prepared materials, the material obtained at 350 °C demonstrates the first discharge capacity as high as 308 mAh g-1 in the range of 4.0 ∼1.7 V at a current rate of 30 mA g-1 and remains at a stable discharge capacity of 250 mAh g-1 within 30 cycles.
