Abstract
A flame-retardant lithium secondary battery is provided that has better battery performance and higher safety than conventional batteries. The lithium secondary battery uses a positive electrode that includes a positive electrode active material of the general formula (1) below, and a nonaqueous electrolytic solution in which an ionic liquid that contains bis(fluorosulfonyl)imide anions as an anionic component is used as the solvent, (1) LiNixMnyO4, wherein x and y are values that satisfy the relations x+y=2, and x:y=27.572.5 to 22.577.5.
