High-compaction lithium iron phosphate positive electrode material, preparation method thereof, positive electrode and battery including the same

Abstract

A high-compaction lithium iron phosphate positive electrode material, a preparation method thereof, a positive electrode and a battery including the same. The high-compaction lithium iron phosphate positive electrode material comprises lithium iron phosphate of formula LiFe1-x-yVxTiy(BO3)z(PO4)1-z, and carbon coated on a surface of the lithium iron phosphate, wherein, 0.001x0.01, 0.001y0.01, and 0.05z0.2. The high-compaction lithium iron phosphate positive electrode material has a high compacted density, a high specific capacity, and excellent rate performance and cycle performance, and is useful for preparing batteries having a high compacted density, a high capacity, good rate performance and cycle performance, which are suitable for high-end pure electric vehicles having a long driving mileage.
