[0002] Graphite electrodes are widely used in the electrochemistry industry, especially as electrode materials in electrolytic cells. During the electrolysis process, the graphite electrode needs to be connected to the water-cooled joint to ensure the cooling effect of the electrode and the effective transmission of electric energy. However, the existing connection methods between graphite electrodes and water-cooled joints have some limitations and problems. For example, when the graphite electrode needs to be replaced, it is usually necessary to disassemble the water-cooled cover plate, which not only increases the complexity of the operation but also may damage the water-cooling system. Due to the limited contact area between the graphite electrode and the water-cooled joint, or due to the unreasonable design of the connection structure, poor contact occurs, affecting the transmission of electric energy and the cooling effect.
