Serious corrosion in the aluminum current collector occurs when it reacts with electrolyte above the limit voltage. The higher the energy density of an electric double layer capacitor (EDLC), the more it is necessary to understand the aluminum corrosion of the EDLC. Furthermore, in order to study the corrosion of aluminum current collector in EDLC, it is necessary to remove the coated active material from the aluminum.
Physical polishing, Ultrasonic treatment and Heat Treatment are used for removing the active material of the electrode.
The influence of the electrolyte on the aluminum current collector depends on the presence or absence of the active material. The ideal method to remove the active material from an electrode of an EDLC would be by performing ultrasonic treatment for less than 45 seconds after heat treatment at 300° C for 10 minutes on the electrode which has been sufficiently cleaned with ethanol avoiding water.
In this work, we studied the effect of various treatment methods used for removing electrode active material on Al current collector and proposed the most suitable pre-treatment method to correctly analyze the deterioration of the current collector in the EDLC.
