Introduction: The auxiliary electrode is also called the counter electrode, which is only used to pass the current to realize the polarization of the research electrode. When studying cathodic processes, the auxiliary electrode is used as the anode, and when studying anodic processes, the auxiliary electrode is used as the cathode. The area of the auxiliary electrode is generally larger than that of the research electrode, which reduces the current density on the auxiliary electrode, so that it is basically not polarized during the measurement process. Therefore, platinum black electrodes are often used as auxiliary electrodes, and can also be used in the research medium. Remaining inert metallic materials such as Ag, Ni, W, Pb, etc.; in specific cases, specific electrodes are sometimes used. Sometimes for the convenience of measurement, the auxiliary electrode can also be made of the same metal as the research electrode. Graphite rods are cheap to electrodes and can be easily made into larger electrodes. They are suitable for high current and less demanding reactions. It does not matter if the graphite rods have a little loss, and they may be used more in electrodeposition.
