Abstract
A novel process was attempted for synthesis of Li3V2 (PO4)3/LiFePO4 composite cathode material via loading nano-LiFePO4 (LFP) powders onto the outside of micrometer-size spherical Li3V2 (PO4)3 (LVP). The precursor of nano-LFP and LVP were synthesized via “controlled crystallization” and “spray drying” techniques, respectively. The X-ray diffraction characterization, scanning electron microscopy, and electrochemical performance measurements were studied. The results indicated that the prepared Li3V2(PO4)3/LiFePO4 (LVP/LFP) composite material exhibited better discharging capacity at high C rate and at low temperature than that of LFP and bulk LVP/LFP. This can pave an effective way to improve the performance of LFP at high C rate and at low temperature.
