    摘要: A battery capable of improving cycle characteristics is provided. An anode active material layer is formed by a vapor phase method, and includes Si as an element. In the anode active material layer, a plurality of primary particles formed by growth in a thickness direction are included, and the plurality of primary particles are agglomerated to form a plurality of secondary particles. Each secondary particle is separated by a groove formed by charge and discharge, and some of primary particles are split particles split by the groove. The average number of the split particles per secondary particle in 5 or more adjacent secondary particles is 10 or more. Moreover, the primary particles and the secondary particles are inclined to the same side.

    摘要: A current collector capable of relaxing stress and of improving charcteristics, an anode using the current collector, and a battery using the current collector are provided. An active material layer containing Si is provided on a current collector. The current collector contains Cu. Where a peak area resulting from (220) crystal face of Cu obtained by X-ray diffraction is I220, and a peak area resulting from (200) crystal face of Cu obtained by X-ray diffraction is I200, ratio I220/I200 as a ratio of the peak area I200 to the peak area I200 is 2.5 or less. Thereby, even when the active material layer is expanded and shrunk due to charge and discharge, the stress can be relaxed, and separation or the like of the active material layer can be prevented.
