Novel Fluoride-Phosphate Based Cathode Materials for Metal-Ion Batteries

Abstract

The metal-ion battery performance critically depends on the properties of a cathode material. Fluoride-phosphate based cathode materials have captured significant attention due to several advantages compared to conventional oxide materials: the increase of the operating potential due to a higher electronegativity of fluorine, better kinetics arising from a lower affinity of alkali ion to the fluoride anion and a wider structural diversity enabled tuning the electrochemical properties.
