"textContent": "Provided is a positive electrode material which can impart a secondary battery with excellent low temperature output characteristics, excellent high temperature cycle characteristics and excellent durability against high voltage. A positive electrode material of a secondary battery disclosed here includes a positive electrode active substance particle and a coating containing a titanium-containing compound at the surface of the positive electrode active substance particle. A layer having a higher Ti concentration than the Ti concentration at a depth of 500 nm from the surface is formed in a surface portion of the positive electrode active substance particle. The titanium-containing compound in the coating is at least one compound selected from the group consisting of TiO, TiO, wherein n is an integer of 3 or more, and oxides containing Li and Ti.",
