Synthesis of Promising Cathode Material for Lithium Polymer Batteries

Abstract

Original method for synthesis of lithium vanadium phosphate was developed. The method includes two stages: 1st, synthesis of iron phosphate from a mixture of ammonium dihydrophosphate and metal oxide; and 2st, synthesis of lithium vanadium phosphate by thermal lithiation of the product obtained in the 1st stage, with mechanical activation of the precursor in the course of plastic deformation. Our results would provide some basis for further improvement on the Li 3 V 2 (PO 4 ) 3 electrode materials for advance lithium-ion batteries.
