Abstract

Vanadium pentoxide nanofibers (pure and doped by nickel) were synthesized by electrospinning. Pure vanadium pentoxide nanofibers have high specific capacity (330 mAh·g-1 at current density 0,058 A/g), but insufficiently high stability. Nickel doping (5 % at.) led to diameter decrease by 25 % and electrochemical properties improvement: initial specific capacity increased by 40 percent and stability by 80 percent.
