PROBLEM TO BE SOLVED: To increase capacity when a large current is discharged by reducing an internal resistance in a non-aqueous lithium secondary battery, in which a composite oxide of Li and a transient metal is used for a positive electrode. SOLUTION: After at least one of transient metal compounds of Co and Mn and a lithium compound are mixed to form a composite oxide of lithium transition metal in α-NaFeO2 structure, primary particles are coagulated to form in spherical shape. As a result of this, the peak intensity ratio of X-ray diffraction (110)/(003), when the composite oxide is applied/pressed on the electrode, is set to 0.1 or larger. |
