  • Patent number: 9899670
    Abstract: A secondary battery includes: a cathode; an anode; and an electrolytic solution. The cathode contains an active material capable of inserting and extracting an electrode reactant. A ratio IS/IF of a peak intensity IS derived from SO2? and a peak intensity IF derived from LiF2? is 0.04 or more, the peak intensity IS and the peak intensity IF being obtained by negative ion analysis on the active material with use of time-of-flight secondary ion mass spectrometry. Since a secondary battery according to the present invention has an intensity ratio IS/IF of 0.04 or more as obtained by a negative ion analysis of the active material using time-of-flight secondary ion mass spectrometry, the secondary battery is able to achieve excellent battery characteristics.
