    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 reducing swelling is provided. A battery includes a cathode, an anode and an electrolyte. The anode includes a coating containing a S03-containing compound, and the electrolyte contains an electrolyte salt having reduction power. Therefore, on the surface of the anode, the SO3-containing compound is preferentially reduced and decomposed to become a sulfur-containing compound. In the result, decomposition reaction of the electrolyte is prevented.
