Abstract
An iron manganese phosphate precursor, a lithium iron manganese phosphate positive electrode material and a method for preparation thereof, an electrode material, an electrode, and a lithium-ion battery are disclosed. The lithium iron manganese phosphate precursor is represented by (NH)MnFeMPOHO/C, wherein 0.1<x≤0.6 and 0≤y≤0.04, and M is selected from at least one of Mg, Co, Ni, Cu, Zn, and Ti. Lithium iron manganese phosphate positive electrode material prepared from the precursor is uniform in carbon coating, has a dense secondary spherical morphology, is high in compaction density, can improve the electrochemical performance of the lithium-ion battery when applied to the lithium-ion battery, is high in specific capacity and good in cycle performance.
