PROBLEM TO BE SOLVED: To provide a positive electrode material improved in output characteristics and cycle characteristics and suppressed in increase of viscosity of a positive electrode slurry.SOLUTION: A positive electrode composition for a nonaqueous electrolyte secondary battery contains a lithium transition metal composite oxide represented by general formula: LiNiCoMnMO(where, 1.00≤a≤1.50, 0<x≤0.50, 0<y≤0.50, 0.00≤z≤0.02 and 0.40≤x+y≤0.70 are satisfied, and M represents at least one kind selected from the group consisting of Zr, Ti, Mg, Ta, Nb and Mo), and a boron compound containing at least oxygen. The positive electrode composition can be obtained by mixing the lithium transition metal composite oxide and a raw material compound of the boron compound to be fired. |
