Preparation method of dry-method electrode

The invention is suitable for the technical field of batteries, and particularly relates to a preparation method of a dry-method electrode. The preparation method comprises the following steps: by taking a high polymer material as a matrix, carrying out first dry processing on the matrix, so that a conductive material is attached to the surface of the matrix to obtain a three-dimensional conductive current collector; and filling the three-dimensional conductive current collector with the material through second dry method treatment to obtain the electrode plate. The raw materials used for preparing the dry-method electrode are all from biomass resources, and the phenomenon that resources are called by destroying the environment does not exist. The preparation process of the three-dimensional conductive current collector is based on the principles of energy consumption reduction and quality and quantity guarantee, the dry preparation steps simplify the process steps and improve the safety performance, the dry
