    摘要： A battery capable of improving battery characteristics such as cycle characteristics is provided. A coating containing lithium fluoride and lithium hydroxide is provided on the surface of an anode active material layer. The ratio between lithium fluoride and lithium hydroxide is in the range, in which the Li2F+/Li2OH+ peak intensity ratio obtained in positive ion analysis by a Time of Flight-Secondary Ion Mass Spectrometry is 1 or more. The anode active material layer contains a substance containing Si or Sn as an element as an anode active material. By the coating, oxidation of the anode active material layer is inhibited, and decomposition reaction of the electrolytic solution is inhibited.

    摘要： A battery capable of improving the cycle characteristics and the swollenness 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 anode has a coat on an anode active material layer provided on an anode current collector. The coat contains a metal salt. The metal salt has a hydroxyl group and at least one of a sulfonic acid group and a carboxylic acid group. Thereby, lithium ions are easily inserted in the anode and extracted from the anode, and decomposition of the electrolytic solution is prevented.
