Embodiment 1

[0040] Add 8.0 g of activated carbon, 0.8 g of graphene, and 1.2 g of a commercial conductive binder to 45 ml of ethanol-water mixed solution ( V 乙醇 : V 水 =5:5), stirring at high speed for 30 min at room temperature to obtain activated carbon slurry for preparing electrode materials. A metal aluminum sheet with a thickness of 0.4 mm and a size of 8 × 8 cm was placed in ethanol and acetone solutions for ultrasonic cleaning for 15 min for decontamination, and then cleaned with distilled water, and the cleaned aluminum substrate was dried with nitrogen. The activated carbon slurry is sprayed onto the cleaned aluminum current collector by spraying technology to obtain the activated carbon electrode material. The electrode material prepared above was placed in a vacuum oven at 65 ºC to dry the electrode sheet for 6 h. After drying, the electrode sheet was weighed, and the total mass of activated carbon on the symmetrical electrode sheet was 3.0 mg. The empty shell of the super...

Abstract

The invention discloses a color function type super capacitor, prepared by the following method: 1) mixing, stirring and compounding activated carbon, a conductive additive, a conductive binder and anethanol-water mixed solvent into an activated carbon slurry; 2) spraying the activated carbon slurry onto the cleaned current collector by using the spraying technology to prepare the carbon electrode, and then drying the carbon electrode; 3) constructing a "sandwich" structure super capacitor using the carbon electrode and the electrolyte, and then using the encapsulant to encapsulate the constructed super capacitor to prevent leakage of the electrolyte; and 4) coating a colored spinel-type solar absorbing coating onto the surface of the super capacitor to obtain the color function type super capacitor. The invention utilizes the photo-thermal conversion characteristics of the color solar energy absorption coating on the surface of the super capacitor to realize the energy storage application of the super capacitor in a low temperature environment.

Description
