A
lithium secondary battery includes: an
electrode body having a positive
electrode, a negative
electrode, and a separator, the positive electrode and the negative electrode being wound or laminated by means of the separator; and a nonaqueous
electrolyte solution containing a
lithium compound as a
electrolyte. At least one of the positive electrode, the negative electrode, the separator, the nonaqueous
electrolyte solution contains at least one of: (a) an organic and / or inorganic inhibitor, which functions as a Cu-
corrosion inhibitor or a Cu-
trapping agent, (b) a compound having an
organic base and an inorganic acid which are unitarily combined in a molecule, (c) a
cyclic compound containing a N-O radical in a molecular structure, (d) a
cyclic compound which becomes a Mn<2+> supplier in the nonaqueous electrolyte solution, (e) a compound containing an atom showing Lewis acidity and an atom showing Lewis basisity in one molecule, (f) a three-dimensional
siloxane compound, and (g) a
nonionic surfactant; or the nonaqueous electrolyte solution contains: (h) a water-extracting agent, or (i) a
hydrofluoric acid-extracting agent. This
lithium secondary battery exhibits an excellent effect that self-
discharge property, cycle characteristics, long period stability and reliability can be planned.
