LiVPO₄F/C cathode was synthesized by a fast chemical reduction method.

Low toxicity NH₄VO₃ was reduced by oxalic acid at 60 °C in short time.

Polyvinylidene fluoride was used as carbon source with ultrasonic dispersion.

The binding energy peaks corroborate that V in NH₄VO₃ was effective reduced.

LiVPO₄F/C cathode prepared possesses excellent performances.
