PROBLEM TO BE SOLVED: To obtain a positive electrode material for non-aqueous electrolyte secondary batteries which makes charge/discharge electricity in a high rate possible, has high capacity, has excellent durability in charge/discharge- electricity cycle, and has high safety. SOLUTION: In the lithium secondary battery equipped with the positive electrode active material layer which has a lithium transition metal complex oxide as a principal component, the above lithium transition metal complex oxide is constituted of a mixture with a lithium-nickel-manganese-M complex having R-3m rhomb structure expressed by LixNiyMn1-y-zMzO2 (however, x is 0.9<=x<=1.2, y is 0.40<=y<=0.60, and z is 0<=z<=0.2, and M is chosen from either of Fe, Co, Cr, or Al), and a lithium-manganese spinel complex oxide having a Fd-3m spinel structure and expressed with LipMn2O4 (however, p is 1<=p<=1.3). |
