LITHIUM IRON PHOSPHATE POSITIVE ELECTRODE MATERIAL, AND METHOD FOR PRODUCING SAME

The present invention provides a lithium iron phosphate cathode material having high electron conductivity and high lithium ion conductivity, in other words, having excellent performance as an electrode material, provided by a carbon coating formed using a small amount of a carbon material, and a method for producing the lithium iron phosphate cathode material. For this purpose, a lithium iron phosphate cathode material (10) has primary particles (11) of lithium iron phosphate coated with a conductive carbon cover layer (13), and the conductive carbon cover layer is characterized by having thick layer portions (13a) with a thickness of 2 nm or greater and thin layer portions (13b) with a thickness of smaller than 2 nm.
