  • PROCESS FOR PREPARING ELECTROACTIVE INSERTION COMPOUNDS AND ELECTRODE MATERIALS OBTAINED THEREFROM
    Publication number: 20140141333
    Abstract: A process for preparing an at least partially lithiated transition metal oxyanion-based lithium-ion reversible electrode material, which includes providing a precursor of said lithium-ion reversible electrode material, heating said precursor, melting same at a temperature sufficient to produce a melt including an oxyanion containing liquid phase, cooling said melt under conditions to induce solidification thereof and obtain a solid electrode that is capable of reversible lithium ion deinsertion/insertion cycles for use in a lithium battery. Also, lithiated or partially lithiated oxyanion-based-lithium-ion reversible electrode materials obtained by the aforesaid process.
