PROBLEM TO BE SOLVED: To provide a high discharge capacity density and high-performance lithium secondary battery. SOLUTION: This lithium secondary battery electrode is provided with a porous lithium film, whose mean height of the irregularities is 0.1-30 μm and width of the irregularities is larger than the means height of the irregularities and less than the ten times of the means height of the irregularities, on the surface of a positive electrode, a negative electrode, or a separator. The porous lithium film is provided by vacuum evaporating, ion plating, or sputtering under prescribed conditions. |
