Abstract
An electrode having both high energy density and ion diffusivity includes an electrode active material layer on either a positive-or negative-electrode current collector, in which the electrode active material layer has a concave/convex shape on its surface in a predetermined pattern at a constant pitch. In a cross-sectional SEM image of the electrode active material layer, linear cracks are unevenly distributed in a concave portion compared to in a convex portion.
