In electrochemical test, the double layer capacitor occurs between two electrodes? Does this occur between counter and working electrode or reference and working electrode?
Yes, in electrochemical test, double-layer capacitors occur between two electrodes. An electrochemical double layer capacitor is an energy storage system based on electrostatic effects that occur between two carbon electrodes with high specific surface areas per volume. The electrodes are immersed in an electrolyte, and a separator between the electrodes is used. Thus we can say that There is an interaction between the working electrode and the auxiliary electrode, but as mentioned above these are two identical carbon electro electrodes.
