| titleOfInvention | A lithium iron manganese phosphate cathode material with iron and manganese elements in full concentration gradient distribution and preparation method thereof |
| abstract | The invention provides a lithium iron manganese phosphate positive electrode material with iron and manganese elements in a full concentration gradient distribution and a preparation method thereof. The lithium iron manganese phosphate positive electrode material comprises a lithium iron manganese phosphate inner core and a thin lithium iron phosphate coated on the surface of the inner core. The coating layer; and along the direction from the center of the lithium iron manganese phosphate inner core to the surface layer of the inner core, the content of manganese decreases in a gradient and the content of iron increases in a gradient. The preparation method includes the following steps: (1) adding an iron salt solution and a manganese salt solution into a reactor, adding a phosphorus source compound solution and an ammonia solution to carry out a co-precipitation reaction to form a phosphate precursor nucleus; (2) not adding a manganese salt solution, Then carry out co-precipitation reaction, ageing, filtration, washing and drying to obtain precursor particles; (3) mixing with lithium source; (4) solid-phase reaction. The invention significantly improves the electrochemical intercalation and delithiation capability of the material, has excellent electrochemical performance, high tap density and discharge specific capacity, and good cycle stability. |
