| description | The invention provides an embedded lithium ferric manganese phosphate positive electrode material and a preparation method thereof, a lithium ion battery and electric equipment. The preparation method of the embedded lithium ferric manganese phosphate positive electrode material comprises the following steps: mixing raw materials including a lithium source, an iron source, a manganese source, a phosphorus source, a carbon source, an additive and a solvent to obtain first mixed slurry; the additive comprises a surfactant; grinding the first mixed slurry to obtain second mixed slurry; drying the second mixed slurry to obtain a precursor; and calcining the precursor in a protective atmosphere to obtain the embedded lithium ferric manganese phosphate positive electrode material. The embedded lithium ferric manganese phosphate positive electrode material is prepared by using the preparation method of the embedded lithium ferric manganese phosphate positive electrode material. The raw material of the lithium ion ba |
