| 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. |
