1. Excellent Corrosion Resistance
Titanium exhibits outstanding corrosion resistance in oxidative media and chloride ion environments, and can withstand the long-term erosion of acidic electrolytes such as copper sulfate, nickel sulfate, and zinc chloride. A dense oxide film (TiO₂) forms easily on its surface, which is highly stable and has a long service life (typically over 5 to 10 years).

2. Good Electrical Conductivity & Low Resistance
Titanium itself has a relatively high resistivity, but its conductivity can be significantly enhanced and the cell voltage reduced by applying special surface treatments, such as coating with noble metal oxide layers, thereby saving electrical energy. Common coating materials include ruthenium-iridium (Ru-Ir) and platinum (Pt).

3. High Strength & Lightweight
Titanium has a density of only 57% that of steel, yet its strength is close to that of common steel. It is easy to install and transport, and can withstand mechanical stress during the electrolysis process. It has good rigidity and is not prone to deformation under long-term current, ensuring the stability of the plate spacing.

4. Surface Characteristics Optimization
The surface can undergo treatments such as sandblasting and activation to enhance the adhesion of the coating, or be designed with specific patterns to facilitate gas release (such as hydrogen evolution during electrolysis). The coating can reduce the overpotential for metal deposition and increase current efficiency.

Frequently Asked Questions
-
Q What makes titanium cathode plates better than stainless steel cathodes in electrolytic processes? ▼Titanium cathode plates offer superior corrosion resistance in acidic and chloride-rich electrolyte environments compared to stainless steel. They form a stable TiO₂ oxide layer on the surface, which significantly extends service life (typically 5–10 years or more). Additionally, titanium is 43% lighter than steel, making installation and handling easier while maintaining excellent mechanical strength.
-
Q What types of coatings are applied to titanium cathodes and what are their functions? ▼The most common coatings applied to titanium cathodes are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These coatings serve dual purposes: they enhance electrical conductivity by reducing cell voltage and energy consumption, and they provide catalytic activity that reduces the overpotential for metal deposition, thereby improving current efficiency and overall process performance.
-
Q In which industries are titanium cathode plates most widely used? ▼Titanium cathode plates are most widely used in hydrometallurgy (copper, zinc, nickel, cobalt, and manganese electrolysis), the electroplating industry (precious metal plating such as gold and platinum), the chlor-alkali industry, electrochemical water treatment for environmental protection, and the preparation of new energy materials including lithium battery precursors and hydrogen production via water electrolysis.
-
Q How long is the typical service life of a titanium cathode plate, and what affects its lifespan? ▼Under normal operating conditions, titanium cathode plates typically last 5 to 10 years or more. Key factors that influence lifespan include the type and quality of the surface coating, the concentration and temperature of the electrolyte, current density, and the frequency of maintenance. Proper surface treatment such as sandblasting and activation prior to coating application also significantly extends service life by improving coating adhesion.
-
Q Are titanium cathode plates environmentally friendly and cost-effective in the long run? ▼Yes. Titanium cathode plates are considered both environmentally friendly and economically advantageous over the long term. Their extended service life reduces the frequency of replacement, lowering maintenance and downtime costs. Titanium is a fully recyclable material, and the noble metal coating used is minimal in quantity. These characteristics align with green manufacturing standards and contribute to reduced energy consumption and lower overall operational costs.
-
Q Can titanium cathode plates be customized for specific electrolytic applications? ▼Yes. Titanium cathode plates can be customized in terms of dimensions, surface patterns, and coating compositions to suit specific electrolytic environments and process requirements. Surface patterns can be engineered to facilitate gas release during electrolysis, while different coating formulations can be selected to optimize catalytic activity, current efficiency, and corrosion resistance for applications ranging from copper refining to hydrogen production.
