Study on ultrafast synthesis of LiV3O8 cathode material for lithium-ion batteries

LiV3O8 has been synthesized by an improved spray-drying method which is dozens of times faster than the conventional route. The as-obtained powder was characterized by XRD, indicating this material was almost pure LiV3O8. The electrochemical performance of LiV3O8 as the cathode material was investigated, which demonstrated that as-prepared LiV3O8 exhibited as high as 340.2 mA h g(-1) discharge capacity in first cycle at current density of 25 mA g(-1); moreover, after 100 cycles at the current density of 125 mA g(-1), it still maintained a high discharge capacity of 241.8 mAh g(-1), suggesting its promising application as the cathode material for Li-ion batteries.
