Cathode material, and a manufacturing method thereof

Excellent battery characteristics, and a lithium ion secondary battery cycle characteristics very excellent, the positive electrode used therefor, and can be easily manufactured, can be further lowered viscosity of the coating solution in the preparation of the positive electrode, the positive electrode material used for the positive electrode, and providing the efficient production methods. A positive electrode active material particles, a positive electrode material having a fluorine-containing carbon material particulate or fibrous on a surface of the positive electrode active material particle. Coverage of the surface of the fluorine-containing carbon material according to the positive electrode active material particles is preferably 10% or more.
