DOPED LITHIUM MANGANESE IRON PHOSPHATE-BASED PARTICULATE, DOPED LITHIUM MANGANESE IRON PHOSPHATE-BASED POWDERY MATERIAL INCLUDING THE SAME, AND METHOD FOR PREPARING POWDERY MATERIAL

摘要

Disclosed is a doped lithium manganese iron phosphate-based particulate for a cathode of a lithium-ion battery. The particulate includes a composition represented by a formula of M_m-Li_xMn_1-y-zFe_yM′_z(PO₄)_n/C, wherein M, M′, x, y, z, m, and n are as defined herein. Also disclosed is a powdery material including the particulate, and a method for preparing the powdery material.
