Nickel Fiber - A Special Fiber With Large Specific Surface Area, High Tensile Strength And Good Flexibility

Production Process:

Nickel fiber is a special fiber with large specific surface area, high tensile strength and good flexibility made from nickel wire through complex processes such as surface treatment, bundling, drawing and electrochemical separation.

Performance Characteristics:

As a new type of material, nickel fiber combines the inherent advantages of metallic nickel and the characteristics of fiber materials, with high tensile strength and good flexibility.

Application direction:

The electrodes of alkaline electrolyzers used to electrolyze water for hydrogen production are currently mostly nickel-based materials used in China, such as pure nickel mesh, nickel foam, or pure nickel mesh or nickel foam as the base and sprayed with high-activity catalysts. The use of nickel fiber felt as electrodes has the characteristics of larger specific surface area, higher tensile strength, and better flexibility than nickel mesh and nickel foam electrodes in terms of thickness, pore size, unit weight, and porosity.

Nickel fiber felt replaces nickel foam as the anode active material skeleton material of MH-Ni batteries, which can increase the charge and discharge times of MH-Ni batteries to thousands of times. At the same time, it can withstand large current shocks and has the characteristics of good voltage stability, large capacitance, large filling amount of active materials, high utilization rate, low internal resistance, and high plate strength. It is one of the main targets for the current international development of electric vehicle batteries. Therefore, using nickel fiber felt to replace nickel foam has become a development direction of MH-Ni batteries.
