Abstract

The invention provides a method of preparing lithium iron phosphate material and lithium iron phosphate power prepared by the method. The method of preparing lithium iron phosphate material mainly comprises the steps of raw material selection, slurry preparation, slurry grinding, pelleting, calcining and the like, and also includes teh step of size selection based on needs. Compared with other conventional method, the method of the invention has teh advantages of simple process, low manufacturing cost and industrial large-scale production. In addition, the invention provides lithium iron phosphate power prepared by the above method, and the power can serve as anode material for lithium ion rechargeable batteries.
