| titleOfInvention | Preparation method of nano-cobalt tetroxide/nitrogen-doped three-dimensional porous carbon framework composites for supercapacitors |
| abstract | The invention relates to a preparation method of nano cobalt tetroxide/nitrogen-doped three-dimensional porous carbon skeleton composite material for supercapacitors, comprising the following steps: (1) washing and drying melamine foam, and then carbonizing at high temperature to obtain a carbon skeleton; (2) The cobalt nitrate hexahydrate, ammonium fluoride and urea are added to deionized water, ultrasonically mixed, and then the carbon skeleton obtained in step (1) is added, and hydrothermally treated; (3) after the hydrothermal product of step (2) is cooled to room temperature, Take out, wash, dry, and calcine to obtain the target product nano-Co 3 O 4 /nitrogen-doped three-dimensional porous carbon skeleton composite material. Compared with the prior art, the present invention uses carbonized melamine foam as the carbon skeleton, which is low in price, saves cost, and accelerates the transmission and diffusion of electrolyte ions, and the prepared composite material enhances the conductivity and power density of the pseudocapacitive supercapacitor. and cycling stability, providing excellent electrochemical performance. |
