Ir-Ta Titanium Anode for Copper Foil Electrolysis
In the production of electrolytic copper foil, the conductivity uniformity, dimensional stability, and durability of the anode have a decisive influence on the thickness consistency, surface quality, and production line operating efficiency of the copper foil. Our Ir-Ta Titanium Anode for Copper Foil Electrolysis at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for the efficient and stable operation of electrolytic copper foil machines. It uses Grade 1 or Grade 2 pure titanium as the substrate, with an iridium-tantalum mixed metal oxide catalytic coating on the surface. The coating maintains stable oxygen evolution catalytic activity in the strongly acidic electrolyte containing copper sulfate and sulfuric acid, providing uniform current distribution across the cathode drum surface several meters wide. The anode maintains dimensional stability during operation, generates minimal sludge, and minimizes the risk of electrolyte contamination, making it suitable for the continuous electrolytic production of lithium battery copper foil, electronic copper foil, and standard copper foil, serving as a reliable electrode solution for ensuring copper foil quality and production efficiency.
This product is for B2B Industrial Use Only. Operators should follow relevant chemical safety protocols and electrolysis operation standards.

Why Choose Our Titanium Anodes?
- Uniform Current Distribution Across Large Surface Areas for Copper Foil Thickness Consistency
The cathode of an electrolytic copper foil machine is a rotating titanium drum with a diameter of 2–3 meters and a width of 1.5–2 meters, requiring the anode to provide uniform current density across the full surface area. Our curved anode plates are precision-machined to fully match the curvature of the cathode drum, with a dense and uniform coating micro-conductive network combined with a multi-point bus bar connection design for large-format titanium plates, ensuring current distribution deviation is controlled within a narrow range across the full surface, providing the foundation for copper foil thickness uniformity. - Curved Plate Structure Optimized for Electrode Spacing and Electrolyte Flow Field
The anode plate adopts a curved design concentric with the cathode drum, forming a uniform and precise electrode gap between the anode and cathode, ensuring stable electrolyte flow and uniform distribution between the electrodes. This structural design facilitates uniform copper ion deposition and smooth venting of oxygen evolution by-products, reducing localized current density concentration and copper foil thickness fluctuations caused by electrode spacing deviations. - Long-Term Stability in Strongly Acidic, High-Temperature Electrolyte
The copper foil electrolyte is a strongly acidic system containing high concentrations of sulfuric acid (100–200 g/L) and copper sulfate, with operating temperatures typically ranging from 50–65°C, placing stringent demands on the chemical and thermal stability of the anode. Our iridium-tantalum coating exhibits a very low corrosion rate under strongly acidic, high-potential conditions, maintaining stable oxygen evolution catalytic activity and structural integrity during long-term high-temperature operation, making it suitable for long-cycle continuous operation of copper foil machines. - Insoluble Anode Avoiding Lead Contamination Risk
Early copper foil production once used lead alloy anodes, with trace lead dissolving during electrolysis and depositing into the copper foil, affecting the purity, conductivity, and mechanical properties of the foil. Our titanium anode is an insoluble anode, avoiding the dissolution of lead and other impurity metals at the source, contributing to the production of high-purity lithium battery copper foil and electronic copper foil, meeting the quality requirements of the new energy and electronic information industries.

Frequently Asked Questions
Q: How is the curvature accuracy of curved anode plates for copper foil electrolysis ensured?
A: The curvature accuracy of curved anode plates directly affects the uniformity of the anode-cathode gap. We employ precision forming processes to fabricate the titanium substrate, using specialized molds and fixtures to control curvature deviation, with finished anode plates undergoing coordinate measuring machine inspection before shipment. For cathode drums of different diameters, we can customize the matching curvature radius according to your design drawings.
Q: What factors affect the service life of iridium-tantalum coated titanium anodes?
A: Key factors include electrolyte acidity, current density, operating temperature, and impurity content in the electrolyte. The presence of fluoride ions, organic additives, and solid particulates in the electrolyte can accelerate coating consumption or cause surface fouling. We recommend periodically monitoring cell voltage trends and electrolyte composition to anticipate coating condition and replacement timing.
Q: How is the coating loading of titanium anodes selected based on line current density?
A: Loading directly determines anode service life. For production lines operating at higher current densities with longer required continuous operation, a higher iridium loading is recommended. Lithium battery copper foil production lines typically operate at relatively high current densities, for which higher loading iridium-tantalum coatings are recommended to meet the demands of long-cycle stable production. You can provide your line operating parameters, and our engineers will offer a matched loading recommendation.
Q: How should anodes be handled when the coating reaches the end of its service life?
A: The titanium substrate remains stable in the copper foil electrolyte environment. The old coating can be chemically stripped, and once the substrate passes inspection, it can be recoated to restore performance to new-anode levels. For large-format curved anode plates, the recoating solution can yield meaningful long-term savings compared to purchasing entirely new anodes. We offer a full-service process including incoming inspection of used anodes, coating stripping, substrate treatment, and recoating.
