A kind of preparation method of hollow cobalt tetroxide nanoparticles/carbon composite material |
| abstract |
A preparation method of hollow cobalt tetroxide nanoparticle/carbon composite material relates to a preparation method of electrode material applied to high energy density supercapacitor. The present invention aims to solve the technical problems of imperfect structural design and low energy density of the existing electrode materials of supercapacitors. The method of the invention embeds the hollow Co 3 O 4 nanoparticles in the interpenetrating porous carbon network framework, and is applied to the electrode material of the supercapacitor, which can not only promote ion diffusion and electron transport, but also the hollow structure of the Co 3 O 4 nanoparticles can Provide more redox active sites, so that the energy density of supercapacitors can reach 104Whkg -1 , which has very good electrochemical application value. |
