Abstract

Provided is a nonaqueous electrolyte secondary battery in which Li<3>PO<4>is added to a positive electrode active material layer and which has excellent high-temperature storage characteristic. The nonaqueous electrolyte secondary battery disclosed herein includes a positive electrode, a negative electrode, and a nonaqueous electrolytic solution. The positive electrode includes a positive electrode active material layer. The positive electrode active material layer includes Li<3>PO<4>, Li<2>WO<4>, and, as a positive electrode active material, a lithium transition metal complex oxide including at least lithium, nickel, manganese, and cobalt. The mass ratio of Li<3>PO<4>to the positive electrode active material is 1% by mass or more and 5% by mass or less. The mass ratio of Li<2>WO<4>to the positive electrode active material is 0.2% by mass or more and 0.9% by mass or less.
