    摘要： A secondary battery capable of improving cycle characteristics is provided. The secondary battery includes a cathode 21, an anode 22, and an electrolytic solution. A separator 23 provided between the cathode 21 and the anode 22 is impregnated with the electrolytic solution. The electrolytic solution contains a solvent and an electrolyte salt. The solvent contains a cyclic compound having a disulfonic acid anhydride group (—S(═O)2—O—S(═O)2—) and succinonitrile. Compared to a case that the solvent does not contain both the cyclic compound having the disulfonic acid anhydride group and succinonitrile or a case that that the solvent contains at least one thereof, chemical stability of the electrolytic solution is improved. Thus, even if charge and discharge are repeated, electrolytic solution decomposition is inhibited.

    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.

    摘要： A battery capable of improving cycle characteristics is provided. An electrolytic solution impregnated with a separator includes an ionic compound with an asymmetric structure such as fluorotrifluoromethyl[oxalage-O,O′] lithium borate as an electrolyte salt. Thereby, compared to the case where an ionic compound with a symmetric structure such as bis[oxalate-O,O′] lithium borate or difluoro[oxalate-O,O′]lithium borate is included as an electrolyte salt, the conductivity of the electrolytic solution is improved.

    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.
