Precursor and preparation method thereof, positive electrode material, positive electrode plate, and lithium-ion battery

Abstract

A precursor and a preparation method thereof, a positive electrode material, a positive electrode plate, and a lithium-ion battery are provided. The preparation method includes: mixing a plurality of first raw material components, and drying to obtain a first precursor MnxFeyMzPO4·nH2O, wherein the plurality of first raw material components include an iron source, a manganese source, a phosphorus source, an M source, and hydrogen peroxide. M represents a metal element, x is 0.10-0.95, y is 0.10-0.95, z is 0.01-0.10, the sum of x, y, and z is 0.95-1.06, and n is any integer from 0 to 10.
