Abstract

The invention relates to the preparation technology of micro-electromechanical system (MEMS) supercapacitors, in particular to a preparation method of composite membrane electrode materials applied to a micro-electromechanical system (MEMS) supercapacitor. The preparation method solves the problems that conducting polymers are small in specific capacity and poor in cycling stability. The method is achieved by the adoption of the following steps that 1) conducting polymer monomers are added to distilled water; then supporting electrolyte is added to the distilled water; and finally electrical conductivity carbon materials are added to the distilled water, so composite solution for electrochemical deposition is manufactured; and 2) a current collector of the MEMS supercapacitor is selected to serve as a working electrode; a platinum sheet is selected to serve as a counter electrode, and a saturated calomel electrode is selected to serve as a reference electrode; and then the working electrode, the counter electrode and the reference electrode are simultaneously placed in the composite solution for the electrochemical deposition to carry out cyclic voltammetry electrochemical polymerization. The preparation method of the composite membrane electrode materials applied to the MEMS supercapacitor is suitable for preparation of the MEMS supercapacitor.

Description

technical field [0001] The invention relates to a preparation technology of a MEMS supercapacitor, in particular to a preparation method of a composite film electrode material applied to a MEMS supercapacitor. Background technique [0002] Supercapacitors, also known as electrochemical capacitors, are a new type of power energy storage element that has emerged with breakthroughs in material science, and are a revolutionary development in the field of electrical energy storage. Supercapacitors not only have the characteristics of large current and fast charging and discharging of traditional capacitors, but also have the characteristics of energy storage of batteries. In recent years, driven by micronano and MEMS (Micro-electro-mechanical systems) technologies, a miniature supercapacitor has emerged, which is called MEMS supercapacitor. As an important branch of supercapacitors, MEMS supercapacitors use etching and other related technologies in the MEMS process to form a thr...
