    摘要： In order to provide a lithium secondary battery having high terminal-to-terminal open circuit voltage at the end of charge, suppressed amount of evolved gas on continuous charge, and superior cycle characteristics, the electrolyte solution thereof comprises either both vinylethylene carbonate compound and vinylene carbonate compound, lactone compound having a substituent at its α position in an amount of 0.01 weight % or more and 5 weight % or less, lactones having an unsaturated carbon-carbon bond in an amount of 0.01 weight % or more and 5 weight % or less, or sulfonate compound represented by the formula below. In the formula, L represents a bivalent connecting group consisting of at least one carbon atom and hydrogen atoms, and R30 represents, independently of each other, an unsubstituted or fluorine-substituted aliphatic saturated hydrocarbon group.

    摘要： The invention intends to provide a high-capacity type non-aqueous electrolyte secondary battery that includes a nickel-containing lithium composite oxide as a positive electrode active material and exhibits good charge/discharge cycle characteristics even under a high temperature environment.The invention is a non-aqueous electrolyte secondary battery including: a positive electrode including a nickel-containing lithium composite oxide as a positive electrode active material; a negative electrode capable of absorbing and desorbing lithium; a separator interposed between the positive electrode and the negative electrode; and a non-aqueous electrolyte including a non-aqueous solvent and a solute dissolved in the non-aqueous solvent. In the nickel-containing lithium composite compound after a discharge to a predetermined cut-off voltage of discharge, the molar ratio r of lithium to the other metal elements than lithium is 0.85 or more and 0.92 or less. The non-aqueous electrolyte includes a fluorine-containing sulfonate compound.
