Q1 What is a titanium cathode plate and how does it work in electrolysis?A titanium cathode plate is an electrode made from high-purity titanium substrate, often coated with noble metal oxides such as ruthenium-iridium or platinum. During electrolysis, metal ions in the electrolyte solution are reduced and deposited onto the cathode surface. The titanium substrate provides mechanical strength and corrosion resistance, while the coating enhances electrical conductivity and catalytic performance, ensuring efficient and stable metal deposition.
-
Q2 Why is titanium preferred over stainless steel for cathode plates in hydrometallurgy?Titanium offers superior corrosion resistance compared to stainless steel, especially in aggressive acidic and chloride-rich electrolyte environments common in hydrometallurgy. Its naturally forming TiO₂ oxide layer provides long-term protection. Additionally, titanium is significantly lighter (about 57% the density of steel) while maintaining comparable strength, making installation and handling easier and reducing structural load.
-
Q3 What coatings are commonly applied to titanium cathode plates and what are their benefits?The most common coatings are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These coatings serve dual purposes: they significantly enhance the electrical conductivity of the titanium surface and provide catalytic activity that reduces the overpotential required for metal deposition. This leads to lower energy consumption, higher current efficiency, and more uniform metal deposition across the cathode surface.
-
Q4 How long is the typical service life of a titanium cathode plate?Under normal operating conditions, titanium cathode plates typically have a service life of 5 to 10 years or more. The longevity depends on factors such as the type and concentration of the electrolyte, operating temperature, current density, and the quality of the surface coating. Proper maintenance, including periodic inspection and re-coating when necessary, can extend the operational lifespan further.
-
Q5 Can titanium cathode plates be used in the new energy sector?Yes. Titanium cathode plates are increasingly used in new energy applications. They serve as cathode carriers in the production of lithium battery material precursors such as electrolytic manganese dioxide (EMD), and they play an important role in hydrogen energy production through water electrolysis. Their excellent corrosion resistance and long service life make them well-suited for these demanding, high-value applications.
-
Q6 Are titanium cathode plates environmentally friendly and cost-effective?Titanium cathode plates are both environmentally friendly and cost-effective over their lifecycle. Titanium is a fully recyclable material, and the long service life of the plates reduces the frequency of replacements, lowering both material waste and maintenance costs. The coatings require only minimal amounts of precious metals, and the improved electrical efficiency of coated titanium cathodes reduces energy consumption — directly supporting green manufacturing and sustainable industrial practices.
