Preparation and electrochemical performance of 7LiFePO 4 ·3Li 3 V 2 (PO 4 ) 3 /C

Nanocomposite LiFePO4·Li3V2(PO4)3/C synthesized by freeze-drying assisted sol-gel method and its magnetic and electrochemical properties

“…LVP is a relatively fast ionic conductor with high potential platform and thermal stability [14][15][16], which is expected to improve electrochemical performances of LFP. Previous studies [17][18][19][20] have shown that xLFP·yLVP/C has better specific capacity, cyclic stability and rate capability than pristine LiFePO 4 /C (LFP/C). It is generally attributed to the mutual doping of V and Fe as well as synergistical effect of LFP and LVP phases, so as to improve the electric conductivity and Li + diffusion of xLFP·yLVP/C.…”
