Product Introduction
We recommend the Titanium Anode For Electrolytic Copper Foil for manufacturers pursuing high-purity copper foil with stable output and extended anode lifetime. Featuring Ir–Ta gradient coatings and proven slot-fit accuracy for imported electrolyzers, it helps control oxygen contamination and supports continuous operation above 200 A/m² with low maintenance cost.

⚠ For Cl⁻ > 50 ppm, special coating is required
⚠ Oxygen content in copper foil linked to anode coating - target <5 ppm
Product Features & Application
■ Verified Low Oxygen Contamination
→ Independent lab confirmed O₂ content in foil <3.2 ppm (standard: <5 ppm for Li-ion batteries)
■ Stable Output at High Loads
→ 200 A/m² continuous operation with voltage fluctuation <±3.5%, reduces surface roughness defects
■ Slot Compatibility with Major Electrolyzers
→ ±0.3 mm CAD fit for Mitsui MX, Hitachi HC-200 systems (verified installation photo available)
■ The Titanium Anode For Electrolytic Copper Foil is ideal for:
✓ High-purity lithium battery copper foil lines
✓ Roll-to-roll continuous electrolysis tanks
✓ Electrolyte systems with mild Cl⁻ intrusion
✓ Retrofit of aging graphite or stainless tank anodes

FAQ
Q1: How long does the anode last at 200 A/m² in acid CuSO₄?
A: Typical design load is 15,000 A·h per dm². At 6 h/day, this equals ~2.5 years considering acid corrosion.
Q2: Can it retrofit our existing Hitachi tank layout?
A: Yes. We support ±0.3 mm slot tolerance and have matched HC-200 models in past deliveries.
Q3: Will this improve copper purity for battery foil?
A: Yes. Testing shows oxygen content drops from 7–8 ppm (graphite) to 3.2 ppm using this anode.
Q4: Can I request test reports before shipment?
A: Sure. We provide ASTM B571 adhesion and coating thickness data per batch, traceable by laser ID.
Q5: What's the cost for 3D CAD modifications?
A: 2D changes (≤5 size points) are free up to 3 times; full 3D modeling is $150/revision.
