METHOD FOR MANUFACTURING LMFP COMPOSITE POSITIVE ELECTRODE PARTICLES

A method for manufacturing LMFP composite positive electrode particles includes the steps of: placing a plurality of lithium ion conductor particles and LMFP particles, a carbon source and a first dispersant into a ball mill for mixing to form a mixed slurry, wherein each of the lithium ion conductor particles formed by a first oxide or phosphate capable of conducting lithium ions, or is formed by a second oxide with a garnet structure or a perovskite structure; then performing a drying on the mixed slurry to obtain a plurality of mixture powders; and then placing the mixture powders into a sintering furnace for performing an oxygen-free sintering to cause that the carbon source performs a dehydration reaction to produce carbons and other residues to form a conductive layer coated on the outer surface of each of the LMFP particles.
