Research of Lithium Ferrous Phosphate by Microwave Technique

Article Preview

Abstract:

In order to developing high-value-added products and making full use of phosphate resources, Lithium Iron Phosphate were synthesized in the controlled atmosphere, using electronic grade phosphoric acid from Yunnan province, ferrous oxalate and Lithium carbonate by microwave processing. The variety of particles and distribution in different conditions of the mixing and grinding, the influence of appearance and property of the Lithium Iron Phosphate in different conditions of microwave power, microwave time and reaction temperature were discussed. Based on the experiment the optimized process conditions have been obtained. Some of the samples were characterized by XRD, SEM, electric capacity, chemical analysis, cycle performance and phase analysis. The experimental results show that the microwave synthesis method of Lithium Ferrous Phosphate is feasible.
