Abstract
A secondary battery includes: a cathode; an anode; and non-aqueous electrolytic solution including a cyclic ether compound that includes a skeleton and one or more substituent groups introduced into the skeleton. The skeleton includes one or more four-or-more-membered oxygen-containing rings. The one or more substituent groups each are a monovalent group represented by Formula (1).—X—O—R (1)(X is one of a divalent chain saturated hydrocarbon group, a halide group thereof, and nothing. R is one of a monovalent chain saturated hydrocarbon group, etc. At least one of one or more Rs includes one or more of the monovalent chain unsaturated hydrocarbon group, the monovalent cyclic unsaturated hydrocarbon group, the monovalent oxygen-containing cyclic unsaturated hydrocarbon group, the halide group thereof, and the monovalent group obtained by bonding two or more thereof, and includes a carbon-carbon multiple bond (one of —C═C— and —C≡C—) bonded to an ether bond (—O—).)
