Abstract
A method of manufacturing a cathode active material and a nonaqueous electrolyte secondary battery including the cathode active material and having a large capacity, an excellent cycle characteristic at high environmental temperature and satisfactory discharging characteristic under a large load are provided. Cobalt salts, lithium salts and sodium hydroxide salts are mixed with one another and a prepared mixture is baked so that a cathode active material is obtained which is expressed by LixCo1-yAlyO2 (where 0.05 ≤ x ≤ 1.10 and 0.01 ≤ y < 0.10) is obtained.
