Abstract

See full text

A lithium secondary battery of the present invention includes: a positive electrode; a negative electrode; a nonaqueous electrolytic solution; and a separator. The positive active material contains a lithium-containing composite oxide containing nickel. A molar ratio of a total nickel amount with respect to a total lithium amount contained in the entire positive active material is 0.05 to 1.0. The nonaqueous electrolytic solution contains 0.5 to 5.0 mass % of a phosphonoacetate-based compound represented by the following General Formula (1). In the Formula, R1, R2, and R3 independently represent an alkyl group, an alkenyl group, or an alkynyl group having 1 to 12 carbon atoms, which may be substituted by a halogen atom, and “n” represents an integer of 0 to 6.
