Template as well as manufacturing method and use, intermediate structure and lithium secondary battery electrode

A manufacturing method for an intermediate structure of a lithium secondary battery electrode, the manufacturing method for the intermediate structure comprising the following steps:

• synthesizing a template:
• bonding a film material onto a substrate through an adhesive layer, and allowing both the film material and the adhesive layer to be formed with through holes, central axes of the through holes being perpendicular to a plane where the substrate is located;
• wherein the substrate is a conductive substrate, and the film material is a flexible polymer thin film, the polymer thin film is at least one of a poly tetra fluoroethylene (PTFE) thin film, a polyethylene glycol terephthalate (PET) thin film, a polypropylene (PP) thin film, a polycarbonate (PC) thin film or a polyimide (PI) thin film, a hole spacing between adjacent through holes is 5 μm to 20 μm, a ratio of a thickness of the film material to a hole diameter of the through holes is 1:3 to 3:1, the thickness of the film material is 2 μm to 50 μm, wherein the template is used for preparing the lithium secondary battery electrode on one surface or two surfaces of the template;
• growing a conductive material in through holes such that one-dimensional columnar structures perpendicular to the substrate are formed in the through holes;
• and removing the film material in the template to obtain the intermediate structure, the one-dimensional columnar structures is used for coating an active material layer on an outer surface of the one-dimensional columnar structures, and an electrode active material of the active material layer includes at least one of silicon and silicide.
