Titanium-based Lead Dioxide Anode

The Titanium-based Lead Dioxide Anode consists of a titanium substrate coated with a high-purity lead dioxide (PbO₂) layer. This structure combines the corrosion resistance of titanium with the high current efficiency and oxygen evolution potential of PbO₂. It is ideal for demanding electrochemical environments such as copper, nickel, and manganese electrowinning.

Product Introduction

Corrosion resistant titanium based lead dioxide anode

Advanced PbO₂ Coating on Titanium Substrate for Extended Anode Life

Durable, High-Performance Anode for Acidic Electrolytic Applications

Structure & Coating Composition

The anode adopts a three-layer composite structure to maximize performance and service life:

Substrate Layer: Grade 1/Grade 2 pure titanium plate/mesh
Intermediate Layer: Conductive tin-antimony oxide layer (improves coating adhesion)
Active Coating Layer: α-PbO₂ + β-PbO₂ dual-phase composite coating

α-PbO₂: Provides excellent mechanical strength and adhesion
β-PbO₂: Delivers high electrocatalytic activity and current efficiency

Coating Thickness: 50–150 μm (customizable based on application requirements)

Key Electrochemical Features

High oxygen evolution overpotential (≥1.75 V vs. SHE in 1M H₂SO₄)
Low electrical resistivity (≤2×10⁻⁵ Ω·cm)
Stable current efficiency (≥94% in copper electrowinning)
Excellent dimensional stability (deformation rate <0.1% after 1000 hours operation)
Strong resistance to sulfuric acid and heavy metal corrosion

Product Advantages

High Current Efficiency & Energy Saving
Low oxygen evolution overpotential reduces cell voltage by 0.15–0.3 V compared with traditional lead anodes, saving about 8–15% of electricity consumption, which brings significant cost savings for long-term operation.
Longer Service Life
Dense lead dioxide coating has excellent corrosion resistance in sulfuric acid electrolyte, with service life 30–50% longer than conventional lead-silver anodes, reducing replacement frequency and maintenance cost.
Stable Coating Quality
The coating is firmly bonded to the titanium substrate, not easy to peel off. The uniform coating ensures stable current distribution and consistent electrolysis performance throughout the service cycle.
High Current Density Adaptability
Can operate stably under higher current density (up to 500 A/m²), which helps increase tankhouse production capacity without increasing cell quantity.
Low Lead Pollution Risk
Compared with traditional lead alloy anodes, lead dioxide coating has lower dissolution rate, reducing lead ion content in electrolyte and lead pollution risk in cathode copper product.

Quantifiable Advantages Over Traditional Lead Alloy Anodes

The advanced materials science behind our Titanium-based Lead Dioxide Anode Plate translates directly into operational superiority and significant cost savings, as demonstrated in the comparison below.

Feature	Traditional Lead Alloy Anode	Our Titanium-based PbO₂ Anode	Your Direct Benefit
1. Service Life	Gradually corrodes over time, typically lasting 2-6 years depending on operating conditions.	Extends service life by a minimum of 50%, often exceeding 100% increase. The inert titanium core does not corrode, and the β-PbO₂ layer wears slowly and predictably.	Drastically reduced replacement frequency and costs. Minimizes cell downtime for anode changes, increasing overall plant availability.
2. Corrosion Resistance & Anode Slime	Continuous corrosion leads to the formation of lead-containing sludge (PbO₂, PbSO₄), which contaminates cathodes.	Near-zero corrosion of the substrate. The β-PbO₂ surface is highly stable, resulting in virtually no anode slime generation.	Higher cathode purity (e.g., LME Grade A). Reduces cathode scraping, lowers electrolyte purification costs, and minimizes environmental waste handling.
3. Operational Efficiency	Forms a resistive PbO₂ layer; higher cell voltage is often required over time. Prone to warping.	Maintains a stable, low cell voltage due to its high catalytic activity and permanent shape. The titanium substrate is immune to warping.	Estimated 5-10% reduction in energy consumption due to lower overpotential for oxygen evolution. Stable spacing ensures consistent current density.
4. Total Cost per Ton of Metal	Lower upfront cost, but higher long-term costs for energy, sludge management, and anode replacement.	Higher initial investment with a superior ROI. Data from commercial operations indicate a minimum 3% reduction in integrated production cost per ton of cathode copper, factoring in energy, maintenance, and purity gains.	Direct improvement to your bottom line. Transforms the anode from a consumable into a long-term efficiency asset.
