    摘要： In a charging method for a non-aqueous electrolyte secondary battery which includes a positive electrode including a lithium-containing composite oxide as an active material, a negative electrode including an alloy-formable negative electrode active material, and a non-aqueous electrolyte, a voltage of the secondary battery is detected. When the detected value is smaller than a predetermined voltage x, charging is performed at a comparatively small current value B. When the detected value is equal to or greater than the predetermined voltage x and smaller than a predetermined voltage z, charging is performed at a comparatively great current value A. When the detected value is equal to or greater than the predetermined voltage z and smaller than a predetermined voltage y, charging is performed at a comparatively small current value C. When the detected value is greater than the predetermined voltage y, constant-voltage charging is performed or charging is terminated. Here, x

    摘要： This invention provides a negative electrode and a non-aqueous electrolyte secondary battery including the negative electrode. The negative electrode includes a Li-absorbing element as a negative electrode active material, is free from deformation, separation of the negative electrode active material layer from the negative electrode current collector, and deposition of lithium on the negative electrode current collector, and is excellent in cycle characteristic, large-current discharge characteristic, and low-temperature discharge characteristic.The negative electrode of this invention includes: a current collector having depressions and protrusions on a surface in the thickness direction thereof; and a negative electrode active material layer that includes a plurality of columns containing a negative electrode active material that absorbs and releases lithium ions, the columns being grown outwardly from the surface of the current collector. The negative electrode of this invention is characterized in that the columns are grown at an inclination angle relative to the direction perpendicular to the surface of the current collector, and that the inclination angle of the columns changes reversibly depending on absorption and release of lithium ions by the negative electrode active material.
