METHOD FOR MANUFACTURING COMPOSITE CATHODE PARTICLES BASED ON DUAL-COATED TERNARY OXIDE FOR ELECTROCHEMICAL BATTERY

A method for manufacturing composite cathode particles based on a dual-coated ternary oxide for an electrochemical battery includes the steps of: placing a plurality of large NCM (lithium nickel manganese cobalt oxide) particles and a glass phase material into a first mixer for stirring; then performing a first oxygen assisted sintering on the large NCM particles and the glass phase material mixed by the first mixer to form a plurality of glass-phase-layer-contained NCM particles; then mixing a plurality of small LLZO particles and the glass-phase-layer-contained NCM particles to form a plurality of composite NCM particles; and then performing a second oxygen assisted sintering on the composite NCM particles to form a plurality of sintered powders.
