Abstract

The invention relates to the field of manufacturing thin film electrodes, in particular to a method for manufacturing a three-dimensional thin film electrode by using an abrasive. Aiming at defects including the troubles of deformation machining, difficult-to-control deformation effect, long manufacturing period, low efficiency and the like of the thin film electrode layer on the surface of the existing three-dimensional thin film electrode, the method for manufacturing the three-dimensional thin film electrode by using the abrasive is provided. Solid abrasive particles are placed on the surface layer of the thin film electrode for grinding and pressing so as to press the solid abrasive from top to bottom so that part of the solid abrasive is embedded in the surface layer of the thin filmelectrode to deform the surface layer of the thin film electrode and indentation is generated. The indentation forms corresponding rugged three-dimensional undulation on the surface layer of the thinfilm electrode, then the pressure is released and the solid abrasive is removed to obtain the three-dimensional thin film electrode, the thin film electrode is composed of a base layer and a thin filmelectrode layer arranged on the base layer, and the thin film electrode layer is the surface layer of the thin film electrode. Surface layer deformation processing operation of the three-dimensionalthin film electrode manufactured by the method is simple, the deformation effect is easy to control, and the manufacture period is short and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of thin-film electrode manufacture, in particular to a method for making a three-dimensional thin-film electrode by using abrasive materials. Background technique [0002] The applicant has previously applied for a three-dimensional carbon nanotube film electrode and a three-dimensional graphene film electrode. The surface layers of these two three-dimensional film electrodes are all uneven film electrode layers (ie, conductive films) with three-dimensional undulations. The conductive film of the three-dimensional thin film electrode gets rid of the limitation of the plane area of ​​the original conventional thin film electrode, and obtains a larger contact area than the plane area, thereby creating favorable conditions for the improvement of the performance of electronic devices using thin film electrodes. This thin film electrode with a greatly improved contact area It can be widely used in energy storage batteries,...
