Custom Naked Gold Mesh Current Collector (52–200 Mesh)

A naked gold mesh is a high-purity, chemically inert, woven current collector designed for demanding electrochemistry where stable conductivity and corrosion resistance are essential. With 5N (99.999%) Au purity and configurable mesh counts (52, 60, 80, 100, and 200 mesh), this material provides reproducible electrical contact, uniform current distribution, and excellent long-term stability in both aqueous and non-aqueous environments.

Working Principle

The woven structure forms a conductive network that collects and distributes electrons across an electrode/electrolyte interface while allowing electrolyte, gas, and/or light transmission through the open apertures. This makes gold mesh particularly useful when minimising polarisation losses, improving mass transport, or enabling in-situ optical probing is important.

Key Specifications & Customisation

• Material: 5N (99.999%) pure gold (Au)
• Mesh counts available: 52, 60, 80, 100, 200 mesh (open area depends on wire diameter and weave)
• Custom options: sheet size/shape, wire diameter, weave style, edge finishing, tabs/leads, and frame mounting on request
• Surface: “naked” (uncoated) metallic gold for direct electrochemical contact
  
  

Compatibility

• Works with standard electrochemical cells as a counter electrode or current collector
• Suitable for fuel cell / electrolyser test fixtures (including high-temperature or humid environments where corrosion resistance matters)
• Can be integrated into spectroelectrochemical cells as a semi-transparent conductive electrode depending on mesh/open area
• Pairs well with potentiostats, battery cyclers, and in-situ Raman/UV–Vis spectroelectrochemistry setups
  
  

Typical Applications

• Counter electrodes for rigorous electrochemical testing
• Current collectors for gas diffusion electrodes and porous architectures
• SOFC/SOEC component testing, PEM-related R&D, and corrosion studies
• In-situ optical electrochemistry requiring a conductive, open structure
