Abstract
A secondary battery includes a cathode, an anode, and a nonaqueous electrolytic solution. The nonaqueous electrolytic solution includes a compound represented by M[(Z1Y1)(Z2Y2)N](where M is a metal element, each of Z1 and Z2 is one of groups such as as a fluorine group, and each of Y1 and Y2 is one of groups such as a sulfonyl group), a compound such as a compound represented by R1-CN (where R1 is a monovalent hydrocarbon group), and a compound such as a compound represented by R22-(CN)(where R22 is an n-valent hydrocarbon group, and n is an integer of 2 or more). A content of the compound represented by [(Z1Y1)(Z2Y2)N]in the nonaqueous electrolytic solution is within a range of 2.5 mol/dmto 6 mol/dmboth inclusive.
