Silver Plated Titanium Expanded Metal Mesh Anode Mesh with 1.3*2.6mm Micro-Diamond Pattern for Extreme Corrosion Resistance
This high-precision Titanium Expanded Mesh is a foundational component for next-generation energy storage and conversion. Engineered from high-purity Titanium (typically Grade 1 or Grade 2), it combines extreme chemical stability with a lightweight, high-strength architecture.
The 1.3mm × 2.6mm micro-diamond pattern is specifically optimized for stack efficiency, providing a superior balance of open area for ion transport and a dense structural matrix for active material adhesion.

Titanium's ability to form a stable, self-healing oxide layer ensures the mesh remains inert in aggressive electrochemical environments. It is highly resistant to pitting and stress corrosion, making it the ideal substrate for long-cycle-life batteries and fuel cells operating under harsh conditions.
The 1.3mm (SWD) × 2.6mm (LWD) aperture is meticulously calibrated to provide a high Specific Surface Area. This maximizes contact points for catalysts or active battery pastes, ensuring uniform current distribution and reducing the risk of localized overheating.
As an expanded metal product, this mesh is formed from a single sheet without welds, joints, or weaves. This "one-piece" construction offers superior mechanical rigidity and electrical continuity. At roughly 45% the weight of steel, it is critical for applications where power density and weight reduction are paramount.
The angled strands of the expanded structure promote micro-turbulence, which enhances gas diffusion and prevents bubble accumulation on the electrode surface. This is vital for maintaining high reaction rates in fuel cells and water electrolyzers.
- Hydrogen Fuel Cells (PEM & Alkaline): Functions as a high-performance current collector and structural support for the Gas Diffusion Layer (GDL)
- Water Electrolysis: Serves as the base anode/cathode substrate for Green Hydrogen production, often coated with electrocatalysts
- Advanced Batteries: Used as a lightweight grid for high-energy-density batteries, including lithium-ion and solid-state systems
- Cathodic Protection: Acts as a durable anode mesh for protecting steel structures in marine or underground environments
