Abstract:
The synthesis methodology of nanofibers consisting of vanadium oxides phases mixture and experimental data analysis on their application as the cathode material basis for lithium-ion battery are presented. Vanadium oxide nanofibers were synthesized by electrospinning method. It was shown that increasing the concentration of V$^{4+}$ ions (obtaining nanofibers consisting of vanadium oxides phases mixture) had a positive effect on the electrochemical properties of the material. The initial specific capacity of the material is comparable with the capacity of the material made of pure vanadium pentoxide nanofibers, but the rate of capacity loss decreases: the material retains 83.1% of the specific capacity after 100 charge-discharge cycles.
