Overview
Nickel mesh collector is a specialized porous material made from high-purity nickel wires woven into a grid pattern. It serves as a critical component in electrochemical devices due to its excellent electrical conductivity and durability in harsh environments. Unlike solid nickel sheets, the mesh structure provides a high surface area-to-volume ratio, enhancing electrode performance in applications like lithium-ion batteries and alkaline fuel cells. Industrial-grade mesh typically has purity levels of 99.5% or higher to minimize resistance and chemical reactivity.
Physical and Chemical Properties
The material exhibits exceptional thermal stability, maintaining structural integrity up to 400°C in oxidizing environments. Its open-area ratio (typically 30-70%) and wire diameter (commonly 0.05-0.5mm) can be customized for specific current density requirements. Electrochemically, nickel mesh forms a protective oxide layer that prevents further corrosion while maintaining conductivity. The standard resistivity is approximately 6.84 μΩ·cm at 20°C. Alloy variants may include nickel-chromium or nickel-copper blends for enhanced properties in specialized applications.
Main Applications
Primary use is in battery manufacturing, particularly as current collectors for cathodes in Li-ion and Ni-MH batteries. The mesh structure facilitates electrolyte penetration and reduces electrode polarization. In fuel cells, it functions as gas diffusion layers in PEMFCs and SOFCs. Other applications include electrolysis electrodes for hydrogen production, EMI shielding materials, and high-temperature filtration systems for corrosive gases. Recent R&D explores its use in flexible electronics and supercapacitors.
Safety and Storage
While nickel mesh is generally stable, fine particles generated during cutting may pose inhalation risks (nickel is a known sensitizer). Use PPE including gloves and NIOSH-approved respirators when handling raw mesh sheets. Store in moisture-proof packaging away from acids and oxidizing agents. For long-term storage (>6 months), nitrogen-purged containers are recommended to prevent surface oxidation. Bulk rolls should be stored horizontally to prevent deformation.
B2B Procurement Guide
Key specifications to verify: mesh count (lines per inch/cm), wire diameter tolerance (±5% is industry standard), and purity certification (ASTM B162 or equivalent). For battery applications, request low-sulfur variants (<50ppm) to prevent capacity degradation. Lead times for custom weaves typically range 4-8 weeks. Sample testing should include sheet resistance measurements and accelerated corrosion testing (e.g., salt spray per ASTM B117). Consider suppliers with ISO 9001 certification for quality assurance.
