    摘要： A battery capable of securing the cycle characteristics and the storage characteristics is provided. The battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. The electrolytic solution contains a solvent, an electrolyte salt, and a sulfone compound having a given structure (sulfonic acid, carboxylic acid anhydride not having an aromatic ring). Compared to a case that an electrolytic solution does not contain the foregoing sulfone compound, the decomposition reaction of the electrolytic solution is prevented.

    摘要： A secondary battery capable of improving battery characteristics is provided. The secondary battery includes a cathode 21 containing a cathode active material capable of inserting and extracting an electrode reactant, an anode 22 containing an anode active material capable of inserting and extracting the electrode reactant, and an electrolyte containing a solvent and an electrolyte salt. At least one of the cathode 21, the anode 22, and the electrolyte contains a radical scavenger compound. The radical scavenger compound is a compound in which a group having a radical scavenger function exists as a matrix, to which one or more carboxylic metal bases or one or more sulfonic metal bases are introduced. Chemical stability of the cathode 21, the anode 22, or the electrolyte containing the radical scavenger compound is improved. Thus, at the time of charge and discharge, decomposition reaction of the electrolytic solution is easily inhibited.
