| titleOfInvention | Preparation method of composite material |
| abstract | A preparation method of a composite material belongs to the technical field of production of electrode materials of super capacitors. Mixing glucose and a potassium permanganate aqueous solution to form a carbon-containing precursor solution, then placing the carbon-containing precursor solution in a closed container, placing the container in a forced air drying oven at 100-180 ℃ until the end, and cooling, filtering, washing and drying the mixture to obtain a manganese carbonate/carbon precursor; dispersing a manganese carbonate/carbon precursor in deionized water to form a manganese carbonate/carbon solution, and dissolving cobalt nitrate hexahydrate to obtain a mixed solution; and (2) placing the mixed solution in a closed container, reacting at the temperature of 80-140 ℃, cooling, filtering, cleaning and drying to obtain manganese carbonate/carbon @ cobalt hydroxide powder, and calcining at the temperature of 400-700 ℃ to obtain the uniquely interconnected porous manganese sesquioxide/carbon @ cobaltosic oxide cubic composite material which can be used as a high-efficiency electroactive electrode of an electrochemical supercapacitor. |
