Light enhancement effect transparent supercapacitor and preparation method thereof

Abstract

The invention provides a method for preparing a transparent supercapacitor with a light enhancement effect. The method comprises the following steps of reacting with foamy copper serving as a substrate of an electrode material to obtain a copper-doped nickel oxide taking a copper oxide array as a substrate to obtain an electrode material of the transparent supercapacitor with the light enhancementeffect; taking foamed nickel as a counter electrode material matrix, taking activated carbon as an active material for uniform coating to serve a counter electrode of a light enhancement effect transparent supercapacitor, taking a sodium ion battery diaphragm as a super capacitor diaphragm, taking a potassium hydroxide solution as a super capacitor electrode solution, stacking the electrode material, an insulating diaphragm and the counter electrode and then putting the electrode material, the insulating diaphragm and the counter electrode into a transparent packaging material, injecting a proper amount of electrolyte and then packaging to obtain and the transparent super capacitor with the light enhancement effect. The supercapacitor with a transparent device is prepared by adopting a super capacitor electrode material with photoresponse, so that the specific capacitance of the supercapacitor is improved and the cycling stability of the supercapacitor is enhanced under the irradiation of sunlight.

Description
