Controlled synthesis of Li3VO4/C nanofibers as anode for Li-ion batteries
Li 3 VO 4 /C nanofibers (LVO/C NFs) with tunable morphology and microstructure are prepared via an aqueous-based electrospinning approach. LVO/C NFs with smooth surface and high defects in C (LVO/C NFs-1) are obtained by pre-annealing in air, while pre-annealing in N 2 leads to the formation of LVO/...
