    摘要: The invention provides a battery, which can improve battery characteristics such as high temperature storage characteristics. The battery comprises a battery device, wherein a cathode and an anode are wound with a separator in between. The anode contains an anode material capable of inserting and extracting Li as an anode active material. An electrolytic solution is impregnated in the separator. The electrolytic solution contains a solvent, and an electrolyte salt such as Li[B(CF3)4] dissolved in the solvent, which is expressed by a chemical formula of Li[B(RF1)(RF2)(RF3)RF4]RF 1, RF 2, RF 3, and RF 4 represent a perfluoro alkyl group whose number of fluorine or carbon is from 1 to 12, respectively. Consequently, high temperature storage characteristics are improved.

    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.
