摘要

PPROBLEM TO BE SOLVED: To provide a conductive complex improving the electric conductivity of a lithium-containing transition metal compound, such as olivine type iron phosphate lithium, and suppressing solubility to an electrolyte, a method of manufacturing the same, a positive electrode material for a lithium ion secondary battery using the conductive complex, and a lithium ion secondary battery having a high discharge capacity and excellent cycle life characteristics. PSOLUTION: The lithium ion secondary battery having a high discharge capacity and excellent cycle life characteristics, and being highly safe, is provided by synthesizing the conductive complex by coating the surface of a lithium-containing transition metal compound 2, represented by olivine type iron phosphate lithium, with a conductive polymer 1 obtained by in situ polymerization, and using the conductive complex as a positive electrode material.
