Abstract
The invention belongs to a lithium ion battery electrode material synthesized by using a full-solution process. The lithium ion battery electrode material is prepared by the following steps of: preparing a precursory solution of lithium iron phosphate by taking an organic solvent, a lithium salt dissolved in water or the organic solvent, a ferric salt dissolved in water or the organic solvent, a compound being dissolved in water or the organic solvent and containing phosphate radicals and a compound being dissolved in water or the organic solvent and containing carbon elements as raw materials; spraying to form a nano-grade precursory solution of the lithium iron phosphate; and calcining the nano-grade precursory solution of the lithium iron phosphate, which is obtained through spraying, at a protective atmosphere to obtain a nano-grade lithium iron phosphate material. The produced lithium iron phosphate has high specific capacity, excellent cycle performance, higher compaction density and favorable processing performance; all the raw materials are dissolved in water or the organic solvent, a synthesis process is simple, few control parameters exist in the process of synthesizing the lithium iron phosphate and easy to control, and the produced electrode material has good consistence during large-scale production.
