The three-dimensional fish scale-shaped holes comprise a plurality of rows of arc-shaped structures, the lower row of arc-shaped structures and the upper row of arc-shaped structures are arranged in a staggered mode, and the arc tops of the lower row of arc-shaped structures press the end portions of the upper row of arc-shaped structures. The aperture ratio of the three-dimensional fish scale-shaped holes is 25-50%. The specific surface area of the three-dimensional fish scale-shaped hole is 1.2-1.5 times of that of the planar open hole. When the area of the electrode is increased, the electrolyte can pass through the cathode electrode, the stirring effect is enhanced, the influence of concentration gradient is reduced, the leaching rate and the current efficiency are improved, and the production capacity of the electrolytic cell is improved.
