Nickel foam is a widely used current collector substrate, especially in electrochemical energy storage devices such as batteries and supercapacitors, as well as in the field of electrocatalysis. Its unique properties make it an advantageous choice:
High Conductivity: Nickel is an excellent conductor that ensures efficient electronic transmission and minimizes internal resistance, which is crucial for optimal performance of energy storage systems.
Large specific surface area: provides abundant sites for the load of active substances, increasing the contact area between the electrode Material, current collector, and electrolyte, thereby enhancing the electrochemical reaction.
Efficient Electrolyte Permeation and Ion Transport: Open pores allow for rapid diffusion of electrolyte ions, shortening ion transport paths and improving charge/discharge dynamics.
Adapting to Volume Changes: The porous nature helps accommodate changes in the volume of active materials during cycling, enhancing structural stability and cycle life.
Superior Mechanical Strength and Durability: Nickel foam offers extreme mechanical strength and robustness, capable of withstanding physical stresses during manufacturing and operation. Long-term stability is maintained even under repeated mechanical or thermal cycles.
Corrosion Resistance: Nickel is known for its good corrosion resistance, which is important for long-term stability in various electrochemical environments, especially in alkaline solutions, where it is highly effective.
Thermal Conductivity and Stability: Good thermal conductivity helps dissipate heat generated during battery operation, improving safety and longevity. It is also thermally stable, ensuring consistent performance even in high-temperature conditions.
Lightweight: Despite its strength, nickel foam is lightweight, which helps reduce the overall weight of the device, which is particularly important for portable electronics and electric vehicles.
Versatility: It can easily coat or modify different active materials, making it suitable for various types of batteries (e.g., lithium-ion, nickel-metal hydride, solid-state batteries) and supercapacitors. It can also be used in catalysis, filtration, and thermal management.
