example 1

[0027] The washed celery was vacuum freeze-dried in a freeze dryer for 48 hours. Place the completely dried sample in a tubular resistance furnace, heat it up to 500°C under nitrogen protection, and carbonize it at a constant temperature for 3 hours. , and then cooled to room temperature, rinsed and dried with hydrochloric acid to prepare a porous activated carbon material, such as figure 1 shown. Put the porous activated carbon material and aniline in a 1mol / L dilute hydrochloric acid solution according to the mass ratio (1:1) and mix them thoroughly, and add persulfuric acid with the molar mass of aniline to the above solution drop by drop under the condition of ice-water bath Ammonium solution, stirring while adding dropwise until the ammonium persulfate solution is added dropwise, then continue to stir the solution for 12 hours and then filter, rinse the product with deionized water for several times until the filtrate pH=7, then vacuum dry the product, porous activated c...

Abstract

The invention belongs to the technical field of preparation of supercapacitor electrode materials in the functional material, and particularly relates to a method for preparing a carbon-based material as the supercapacitor electrode material by carbonizing an activated carbon / polyaniline composite material. The method is characterized by the preparation of an activated carbon composite material by carbonizing the activated carbon / polyaniline composite material. The method includes preparing a porous activated carbon material by taking celery as the carbon source; preparing an activated carbon / polyaniline composite material by means of in-situ polymerization, and preparing a high-performance activated carbon composite material by carbonizing the activated carbon / polyaniline composite material. The prepared activated carbon composite material has the advantages of easy availability of raw materials, simple process and flow and large specific capacitance. The activated carbon material and the activated carbon composite material are respectively used to prepare supercapacitor electrodes to show that the activated carbon composite material for preparing the supercapacitor electrode has great development potential.

Description

technical field [0001] The invention belongs to the technical field of preparation of supercapacitor electrode materials in functional materials, and in particular relates to a method for preparing activated carbon composite materials as supercapacitor electrode materials by carbonizing activated carbon / polyaniline composite materials. Background technique [0002] In order to build a resource-saving and environment-friendly society, seeking a new type of energy equipment with high efficiency and no pollution has become a hot spot in today's society. Supercapacitor is a new type of energy storage device developed in recent years. It has the characteristics of high power density, long service life, wide temperature range and green and pollution-free, making it expected to replace lithium batteries and ordinary supercapacitors as a new type of energy storage device. energy storage device. [0003] One of the key factors determining the performance of supercapacitors is the pe...
