| titleOfInvention | Super capacitor electrode material with large working potential window and preparation method thereof |
| abstract | The invention provides a super capacitor electrode material and a preparation method thereof, wherein a core-shell structure composite material which takes hexagonal flaky nickel hydroxide with a specific crystal form as a core and takes porous flaky manganese dioxide with a specific crystal form as a shell is arranged on the surface of a base material of foamed nickel. After nickel hydroxide is obtained on a foamed nickel substrate through hydrothermal reaction, a manganese dioxide layer is electrodeposited in a three-electrode mode to prepare the electrode material. The supercapacitor electrode material is compounded by nickel hydroxide and manganese dioxide with two specific crystal forms and specific shapes and compounded on a porous material, and a working electrode assembled by the electrode material is tested by adopting a three-electrode system, so that the width of a potential window can reach 1V, and the potential window is improved by about more than 70% compared with the potential window of 0.4-0.6V of the conventional electrode material. And the synthesis method is simple and rapid, green and environment-friendly, and has low cost. |
