Abstract

An intermediate structure is used for the preparation of a lithium secondary battery electrode on one side and/or on both sides. The preparation method for an intermediate structure includes the following steps: laminating a film on one side and/or on both sides of a substrate, and forming through holes in the film, the central axis of the through holes being perpendicular to the plane of the substrate; wherein, the substrate is a conductive substrate, and the film is a flexible polymer film; growing conductive materials in the through holes to form a one-dimensional columnar structure perpendicular to the substrate in the through holes; and removing the film to obtain an intermediate structure.
