The Ir-Ta Titanium Anode for Copper Foil Electrolysis serves as the core positive electrode component in the whole electrolytic copper foil production line, which directly determines copper foil surface quality, power consumption and equipment operation cycle. Unlike traditional lead anodes and single iridium coated titanium electrodes, the Ir-Ta Titanium Anode for Copper Foil Electrolysis adopts composite iridium-tantalum oxide coating, solving common pain points of copper foil electrolysis such as coating peeling, high energy loss and uneven copper deposition.
Ultra-Low Cell Voltage & Energy Saving The composite iridium tantalum oxide catalytic layer on Ir-Ta Titanium Anode for Copper Foil Electrolysis features excellent oxygen evolution catalytic activity. Under standard copper foil electrolysis electrolyte environment, the oxygen overpotential of Ir-Ta titanium anode for copper foil electrolysis is reduced by 12%–18% compared with ordinary iridium coated anodes. Mass production data shows that each ton of electrolytic copper foil can save 80–120 kWh electricity when matching our Ir-Ta titanium anode for copper foil electrolysis, greatly cutting long-term production operating costs for copper foil manufacturers.
Super Long Service Life in Strong Acid Electrolyte Copper foil electrolysis relies on sulfuric acid copper electrolyte with strong corrosivity, which brings severe erosion pressure to anode electrodes. The tantalum oxide component in the coating of Ir-Ta Titanium Anode for Copper Foil Electrolysis forms dense anti-corrosion protective film, effectively isolating sulfuric acid medium from titanium substrate. Standard industrial-grade Ir-Ta titanium anode for copper foil electrolysis reaches 8,000–12,000 hours continuous service life under 1000–3000 A/m² current density, 2–3 times longer than pure iridium coated titanium anodes used in copper foil electrolysis workshop.
Uniform Copper Foil Deposition & Zero Impurity Contamination High-quality lithium battery copper foil and PCB thin copper foil require ultra-smooth, pinhole-free foil surface. The Ir-Ta Titanium Anode for Copper Foil Electrolysis realizes consistent current distribution on the whole anode plate surface thanks to uniform Ir-Ta oxide coating thickness (controlled within ±3μm). During electrolysis, the iridium tantalum titanium anode for copper foil electrolysis will not dissolve heavy metal impurities into electrolyte, avoiding black spots, pits and uneven thickness on finished copper foil, greatly improving copper foil yield rate for foil factories.
Customizable Size & Current Density Adaptability Our factory produces tailor-made Ir-Ta Titanium Anode for Copper Foil Electrolysis according to customer’s electrolytic cell parameters. Whether for ultra-thin 4μm–9μm lithium copper foil high-current production line or 12μm–70μm PCB electrolytic copper foil low-speed equipment, the matched Ir-Ta titanium anode for copper foil electrolysis can meet different current density ranges from 800 A/m² to 4000 A/m² without coating failure or performance attenuation.
Stable performance of Ir-Ta Titanium Anode for Copper Foil Electrolysis originates from standardized multi-step production craft, every production link strictly controlled to guarantee coating adhesion and catalytic activity of iridium tantalum layer. All procedures are oriented to the harsh working condition of copper foil electrolysis tank.
Titanium plate is the base carrier of Ir-Ta Titanium Anode for Copper Foil Electrolysis. We select Grade 1 pure titanium plate with stable corrosion resistance as raw material. Pretreatment includes four key steps: surface degreasing, high-temperature alkali washing, acid pickling and sandblasting roughening. Sandblasting creates uniform micro concave texture on titanium surface, which strengthens mechanical bonding force between titanium substrate and subsequent Ir-Ta coating, preventing the Ir-Ta titanium anode for copper foil electrolysis from coating shedding under long-time electrolysis impact.
2.2 Precision Ir-Ta Precursor Solution Preparation
The core catalytic coating material of Ir-Ta Titanium Anode for Copper Foil Electrolysis is iridium chloride and tantalum chloride mixed precursor liquid. Our technical lab adjusts iridium-tantalum metal ratio to 7:3, the optimal formula for copper foil oxygen evolution electrolysis. Raw materials adopt high-purity iridium and tantalum salts (99.99% metal purity) to eliminate impurity interference on electrolytic reaction of copper foil production. The fully stirred Ir-Ta mixed liquid ensures consistent metal content for each batch of Ir-Ta titanium anode for copper foil electrolysis coating.
The coating forming process is the most critical link for Ir-Ta Titanium Anode for Copper Foil Electrolysis. Technicians evenly brush the Ir-Ta mixed precursor liquid on the pretreated titanium substrate surface, then send the anode into segmented high-temperature oven for thermal decomposition oxidation at 480℃–550℃. We repeat brushing and sintering for 12–18 layers to form compact iridium tantalum oxide composite film. Each sintering cycle is precisely timed and temperature-controlled, so the finished Ir-Ta titanium anode for copper foil electrolysis owns dense, crack-free coating structure to resist acid electrolyte penetration.
After coating sintering, every piece of Ir-Ta Titanium Anode for Copper Foil Electrolysis undergoes full performance detection before delivery. Testing items include coating thickness test, adhesion scratch test, accelerated electrolysis life test and cell voltage simulation test under copper foil electrolysis electrolyte. Unqualified semi-finished products will be reworked or scrapped directly to ensure each batch of Ir-Ta titanium anode for copper foil electrolysis meets industrial production standards of electrolytic copper foil manufacturers.
