    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.

    摘要: A battery capable of improving cycle characteristics is provided. An anode active material layer is alloyed with an anode current collector at least in part of the interface with the anode current collector. The anode active material layer contains silicon and oxygen as an element. The average oxygen content in the anode active material layer is 40 atom % or less. When the average oxygen content on the current collector side is A and the average oxygen content on the surface side is B where the anode active material layer is divided into two in the thickness direction, the average oxygen content on the current collector side A is larger than the average oxygen content on the surface side B, and the difference therebetween, A−B is from 4 atom % to 30 atom %.
