摘要：
PROBLEM TO BE SOLVED: To provide a positive electrode for a nonaqueous electrolyte secondary battery having high capacity and high safety in high temperature storage, and to provide the nonaqueous electrolyte secondary battery having the positive electrode.
SOLUTION: The positive electrode for the nonaqueous electrolyte secondary battery has a positive mix layer made of a positive mix containing a positive active material, a conductive auxiliary, and a binder, the positive mix contains a lithium transition metal composite oxide represented by general formula Li
(1+δ) Mn
x Ni
y Co
(1-x-y) O
2 (0≤δ≤0.05; 0.1 2 /g is contained as the conductive auxiliary, and the neutralization amount (A) obtained by neutralization titration of supernatant liquid obtained by immersing 2.5 g of the positive mix in 50 g of neutral water with a sulfuric acid solution having a concentration of 0.01 mol/l is 4.5 ml or less. The nonaqueous electrolyte secondary battery includes the positive electrode.
