(1) High strength: Nickel material has high strength and hardness, can withstand large external forces and pressures, is not easily deformed, thus providing reliable support for cathode materials and ensuring the stability of equipment during long-term operation.
(2) Good conductivity: Large porous nickel steel mesh can quickly and effectively transfer electrons, reduce resistance, minimize energy loss, improve the efficiency of electrochemical reactions, and facilitate the smooth progress of cathodic reactions.
(3) Corrosion resistance: Nickel has a certain degree of corrosion resistance, which can extend the service life of the cathode support network and reduce equipment maintenance and replacement costs.
(4) Macroporous structure: Macroporous design facilitates the flow of electrolyte and diffusion of ions, allowing reactants and products to exchange more smoothly on the electrode surface, improving the mass transfer efficiency of electrochemical reactions and ultimately enhancing the efficiency of the entire electrolysis process.
(5) Good processability: It is easy to perform various processing and forming operations, and can be made into cathode support nets of various shapes and sizes according to different equipment and process requirements.

(1) Battery field:
As a support for certain battery cathodes, it helps to improve the stability and conductivity of cathode materials, enabling better electron transfer during charging and discharging, and enhancing the performance and lifespan of the battery.
For example, in alkaline batteries such as nickel hydrogen batteries and nickel cadmium batteries.
(2) Electrolysis industry:
As the cathode support network of the electrolytic cell, it can withstand various stresses and chemical reactions during the cathodic reaction process, while providing a large surface area for the electrolytic reaction, which is conducive to the transport of ions and the progress of electrochemical reactions.
In processes such as electroplating and electrolytic refining, macroporous nickel steel mesh can serve as a cathode to promote the reduction and deposition of metal ions on its surface, thereby improving electrolysis efficiency and product quality.
