Lithium iron phosphate positive electrode material having a high tap density, method for preparing the same

Abstract

The present disclosure provides a lithium iron phosphate positive electrode material having a high tap density, a method for preparing the same and applications thereof. The method comprises: grinding and spraying in sequence a mixed solution of an iron source, a lithium source, a carbon source and an ion doping agent to obtain a precursor powder; and sintering the precursor powder at a high temperature to obtain the lithium iron phosphate positive electrode material. The method has a simple and controllable process and high productivity. The lithium iron phosphate positive electrode material has excellent characteristics such as a high tap density, and a high specific capacity; and due to its unique morphology, the material may be used by being blended with a ternary material, so that the lithium iron phosphate battery prepared has safety while having the characteristics of ternary batteries such as a high energy density and low temperature resistance.
