METHOD FOR PRODUCING CATHODE MATERIAL FOR LITHIUM BATTERY AND LITHIUM BATTERY

摘要

A method for preparing a positive electrode material for a lithium cell, characterized in that it comprises admixing a compound liberating a phosphate ion in a solution and metallic iron, and dissolving the metallic iron, followed by firing, thereby synthesizing ferric phosphate. The above method further comprising reacting a raw material mixture while grinding it down or refluxing can produce ferric phosphate positive electrode material having a fine particle diameter and exhibiting high activity, through a precursor before firing having a fine particle diameter.
