  "textContent": "Disclosed are: a lithium secondary battery which comprises a positive electrode containing, as a positive electrode active material, a lithium-containing metal oxide that contains at least one metal element selected from nickel, manganese and iron, a negative electrode containing, as a negative electrode active material, a carbon material capable of absorbing and releasing lithium, and a non-aqueous electrolytic solution comprising a non-aqueous solvent and an electrolyte salt dissolved in the non-aqueous solvent, wherein the lithium secondary battery is characterized in that the non-aqueous electrolytic solution contains 0.1 to 5 mass% of 1,2,3,4-tetrahydronaphthalene and 0.1 to 5 mass% of a biphenyl derivative and/or an alkyl phenol derivative; and a non-aqueous electrolytic solution for use in the lithium secondary battery. The lithium secondary battery can have an excellent post-low-temperature-cycle recovery rate even after the battery is exposed to a high-temperature environment.",
