Abstract:
A battery capable of improving the cycle characteristics is provided. A current collector containing copper (Cu), in which ratio I (200)/I (111) between intensity I (200) of a peak originated in (200) crystal plane of copper obtained by X-ray diffraction and intensity I (111) of a peak originated in (111) crystal plane thereof is in the range from 0.5 to 1.5.
