Abstract

The invention provides a fabrication method of a supercapacitor electrode. The fabrication method comprises the steps of synthesizing iron oxide, taking a synthesized Alpha-FeOOH and Alpha-Fe2O3 nanometer material as an electrode active substance, selecting a conductive agent and a binding agent to obtain a suspension liquid, coating the suspension liquid on a foamed nickel electrode which is cleaned in advance, removing a solvent and moisture, and compacting so that powder and the foamed nickel electrode are in close contact to form the supercapacitor electrode. According to the fabrication method of the supercapacitor electrode, provided by the invention, the fabricated supercapacitor electrode has relatively high crystallization degree and has excellent crystallinity and arrangement regularity of crystal structures, and a test shows that the supercapacitor electrode has good conductivity.

Description

technical field [0001] The invention relates to a method for preparing an electrode of a supercapacitor, belonging to the field of nanomaterial preparation. Background technique [0002] Due to its excellent performance, iron oxide nanomaterials are widely used in catalysts, energy storage and conversion equipment, magnetic materials, water pollution treatment, gas sensitive materials, pigments, etc. Supercapacitors have the advantages of high power density, fast charging and discharging, good cycle stability, and long life. As a new type of energy storage device, they have attracted increasing attention. In this paper, on the basis of the current research status of iron oxide nanomaterials, we mainly try to use synthetic methods such as liquid phase precipitation to controllably prepare and synthesize a variety of iron oxide nanomaterials, such as one-dimensional nanostructures, hollow structures, and polyhedral structures. Modern analysis and testing techniques such as ...
