A new technology is proposed for the preparation of lithium phosphate by the co-precipitation method in a turbulent flow cycle equipment. The reaction conditions of lithium hydroxide and phosphoric acid in turbulent flow circulation kettle for the preparation of super-fine lithium phosphate were investigated. X-Ray powder diffraction (XRD)

laser granularity instrument

scanning electron microscopy (SEM)

specific surface and porosity analyzer and thermal analyzer were used to characterize the crystal structure

particle size distribution

morphology

specific surface area and thermal stability of the products. The lithium phosphate prepared by this method had good thermal stability

a narrow particle size distribution of D50=3.25 mm

and a specific BET surface of 13.38 m2·g-1. As a uniformly dispersed super-fine powder material

the lithium phosphate is expected to be a highly active raw material of cathode materials for lithium ion battery or an additive for lithium ion battery electrolyte.
