Problems solved by technology

This is because in a low-temperature environment, the fluidity of the electrolyte in the supercapacitor is hindered, the conductivity is reduced, the mobility of positive and negative ions in the electrolyte is reduced, the rate of adsorption and desorption of positive and negative ions on the electrode surface is reduced, and the electrochemical reaction rate on the electrode surface is reduced. , thus affecting the energy storage characteristics and cycle life of supercapacitors
The performance of supercapacitors is limited by temperature, which greatly limits the promotion and use of supercapacitors in practical environments

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.
