Abstract:
A positive electrode material which is used in a positive electrode of a lithium ion secondary battery disclosed here includes a positive electrode active material including a compound capable of storing and releasing lithium ions, a first coating material disposed on at least a part of the surface of the positive electrode active material, and a second coating material disposed on at least a part of the surface of the positive electrode active material. The positive electrode material is characterized in that the first coating material contains a nickel oxide having a rock salt structure, and the second coating material contains a titanium oxide.
