| titleOfInvention | A kind of preparation method of supercapacitor electrode composite material |
| abstract | The invention discloses a preparation method of a supercapacitor electrode composite material. The method comprises the following steps: adding bagasse into a hydrogen peroxide solution after drying, stirring and dispersing, then transferring it to a high-pressure reaction kettle, keeping the temperature at 200 DEG C for 1.5-2 hours, cooling and drying. After mixing with zinc chloride, add it into deionized water, move it to a high-pressure reactor, keep warm at 220°C, cool, dry, and grind it through a 600-mesh mesh screen; add potassium permanganate into deionized water, and stir completely at room temperature Dissolve, add dilute acid solution to adjust pH value, add ethanol solution and the product of the previous step, stir vigorously and then let stand for aging to obtain gel, freeze-dry to obtain dry gel, grind through 800 mesh sieve to obtain dry gel powder; The dry gel powder was dispersed in deionized water, then starch was added, stirred, the temperature was raised to 80-95 °C, and the stirring was continued for 20-30 min. After the temperature is raised to 800-900° C., N 2 is switched to CO 2 , and the temperature is maintained for 3-4 hours, and then it is switched to nitrogen to start cooling, so as to obtain the electrode composite material. |
