80-mesh N6 Nickel Woven Mesh For Hybrid Acid-Alkaline Water Electrolysis

N6 nickel holds a nickel purity of 99.5% or higher. It shows excellent chemical stability in alkaline electrolytes and neutral electrolytes. Common alkaline media include KOH and NaOH solutions. This material forms a stable passive oxide film on its surface in alkaline hybrid electrolysis systems. It can resist corrosion from strong alkaline solutions at high temperatures up to 1200°C. This reliable anti-corrosion performance removes the need for expensive noble metals on alkaline-side anodes. It helps manufacturers make low-cost electrode substrates. The 80-mesh mesh uses 0.1 mm nickel wire. It has a solid material cross-section. The structure can withstand long-term electrolysis exposure. It avoids surface pitting and stress corrosion cracks in long-term use.

Nickel material has excellent inherent electrical conductivity. Its resistivity stays around 0.07 Ω·mm²/m at 20°C. It supports fast and stable electron transfer on the electrode surface. The plain weave structure creates uniform square holes and regular mesh shapes. It delivers even current density across the whole electrode. It prevents uneven local hot spots during operation. Good electrical conductivity makes 80-mesh N6 nickel mesh a trusted current collector. It acts as a stable conductive path in all electrolyzer stacks. The mesh keeps steady ohmic performance under high current densities of 800 mA/cm² and above. It does not produce obvious voltage loss in high-load working conditions.

The 80-mesh mesh has an average aperture size of about 0.2 mm. It balances open surface area and solid structural density perfectly. Industrial research proves the 80-mesh nickel mesh works well in high-current electrolysis. It helps hydrogen bubbles separate from the electrode surface quickly. The bubbles are smaller and shed faster than those on coarse mesh products. More catalytic active sites open up after bubble detachment. It lowers the overpotential of the hydrogen evolution reaction. The open grid structure boosts gas diffusion efficiency. It also improves electrolyte penetration on the electrode. It supports efficient gas generation at cathode and anode. The cathode works for hydrogen evolution reaction. The anode works for oxygen evolution reaction. It will not cause excessive pressure drop in the electrolyzer. This good bubble control raises overall energy efficiency. It also reduces concentration polarization during electrochemical reactions.

The plain weave design brings stable tensile strength and firm structural rigidity to the nickel mesh. The woven mesh keeps its original hole shape under temperature changes and mechanical pressure. It resists deformation during electrolyzer assembly and daily operation. Traditional expanded nickel mesh comes from cut and stretched nickel sheets. It has unstable mechanical performance and uneven thickness. The woven 80-mesh N6 nickel mesh has predictable mechanical properties. It features uniform thickness on the entire mesh surface. Its tensile strength reaches around 418 MPa. The strong structure fits zero-gap electrolyzer designs. It can bear compression force when electrodes contact diaphragms.

The 80-mesh woven mesh is an ideal base for catalytic layer coating. The mesh surface supports multiple common coating methods. These methods include thermal spray, electrodeposition and cold rolling. Users can coat Raney nickel and other nickel-based catalysts on the mesh easily. The open weave structure maximizes the usable surface area for catalyst fixation. It reserves smooth flow channels for electrolyte movement. The open surface makes full use of coated catalysts. It builds stable gas-liquid-solid three-phase interfaces. The three-phase interface is essential for efficient electrochemical reactions in water electrolysis.

N6 nickel keeps stable mechanical performance and anti-corrosion ability. It works well from room temperature up to 1200°C in reducing or inert environments. Industrial alkaline electrolysis usually runs at 80°C to 95°C. The high thermal stability of N6 nickel fully adapts to this working temperature. It also tolerates temperature differences in hybrid acid-alkaline electrolysis systems. The material resists thermal deformation and oxidation at working temperatures. It maintains consistent working performance for a long service life.
