Abstract

A deep investigation of amorphous V₂O₅–P₂O₅ powders for magnesium batteries communicates the vital properties to achieving the superior electrochemical performance at a 75 : 25 V₂O₅ : P₂O₅ molar ratio. The manipulation of the inter-layer spacing and amorphization of V₂O₅ can enhance Mg²⁺ diffusion and afford a cathode with high-voltage reversibility.
