Abstract
A nonaqueous electrolyte secondary battery which is provided with a positive electrode, a negative electrode and a nonaqueous electrolyte. The positive electrode contains: a positive electrode active material and a compound having a cobalt content of 30% by weight or more. The weight A of the compound and the total weight B of the positive electrode active material satisfy 0.01≤A/(A+B)≤0.15. The negative electrode contains a negative electrode active material. The nonaqueous electrolyte contains propylene carbonate and diethyl carbonate as nonaqueous solvents; the total amount of the propylene carbonate and the diethyl carbonate is 70% by volume or more relative to 100% by volume of the nonaqueous solvents; and the volume ratio of the propylene carbonate to the diethyl carbonate is within the range of from 1:1 to 1:19.
