| titleOfInvention | Method for preparing electrode plate of supercapacitor by hydrothermal method |
| abstract | The invention discloses a method for preparing an electrode plate of a super capacitor by using a hydrothermal method. In the method, cobaltosic oxide powder particles are put into a potassium permanganate solution, the time and the temperature are controlled by a reaction kettle, and manganese dioxide nano-sheets pyrolyzed by potassium permanganate are self-assembled on a cobaltosic oxide shell in a high-temperature and high-pressure environment to form an intermediate composite material with a core-shell structure. And washing the powder after the hydrothermal reaction with deionized water, and drying in a constant-temperature drying oven to obtain the intermediate composite material. The intermediate composite material can be prepared into a super capacitor electrode plate by a coating method, has an ultra-high discharge voltage of 1.4V under a three-electrode system through electrochemical representation, and has excellent performance of a super capacitor. In addition, the core-shell structure prepared by the method has the advantages of simplicity in operation, easiness in control, low cost, no toxicity and the like. |
