Supercapacitor electrode material added with manganese cobalt oxide foamed nickel composite material

Abstract

The invention discloses a supercapacitor electrode material added with a manganese cobalt oxide foamed nickel composite material. The supercapacitor electrode material is prepared from, by weight, 5-6 parts of activated carbon, 30-35 parts of a copper nitrate solution with the concentration being 2 wt%, 80-85 parts of pyrrole, 10-12 parts of chitosan, 100-110 parts of an acetic acid solution with the concentration being 2 wt%, 2-3 parts of sodium dodecyl benzene sulfonate, 3-4 parts of ferric chloride, an appropriate amount of 1 mol/L hydrochloric acid, an appropriate amount of 1 mol/L sodium hydroxide, an appropriate amount of deionized water, 2-2.5 parts of cobalt nitrate, 1-1.2 parts of manganous nitrate, 5-6 parts of urea, 7-8 parts of ammonium fluoride, 4-5 parts of nickel foam and an appropriate amount of absolute ethyl alcohol. The obtained composite electrode material is simple in technology and easy to control, and the supercapacitor prepared from the electrode material is stable in performance, large in specific capacitance and excellent in circulation charging and discharging performance.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a supercapacitor electrode material added with manganese cobaltate foam nickel composite material. Background technique [0002] Supercapacitor is a new type of energy storage device between batteries and traditional capacitors. It has the advantages of both, and has the advantages of high power density, high energy density, short charging time, long service life and no pollution to the environment. As a new type of energy storage device with green environmental protection and excellent performance, supercapacitors are widely used in many fields such as national defense, military industry, electric vehicles, computers, and mobile communications. Conductive polymers have attracted much attention due to their low cost. Conductive polymers with large specific surface areas are considered ideal electrode materials for supercapacitors. Conductive polymers suitable for such cap...

However, in this paper, PTFE is used as the binder to prepare the sheet electrode material. Although the mechanical strength of the electrode material is increased, the addition of the binder increases the resistance of the electrode, reduces the conductivity, and the electrode composition is complex, which is not conducive to the electrode material. Stability, which requires further research on the forming method of the electrode material and how to improve the additive performance of the electrode material
