Add-Ons
Nickel-Iron (Ni-Fe) foam is a 3D porous metallic alloy substrate widely utilized as a high-surface-area electrode backbone, current collector, and catalyst support across water electrolyzers, advanced batteries, and solid oxide fuel cells (SOFCs). By alloying iron into a 3D interconnected nickel web, the foam combines high electrical conductivity, bimetallic electrocatalytic synergy, and tunable open macroporosities (70–95%), while significantly reducing material costs relative to pure noble-metal substrates.
Advanced Batteries & Supercapacitors: (1) Iron-Air & Nickel-Iron Batteries: Serves directly as the conductive porous matrix for active material loading (Fe/Fe-oxide negative electrodes or Ni-Fe layered double hydroxide cathodes), offering high cycle stability and high-rate capability. (2) Sodium-Ion & Lithium-Ion Current Collectors: Functions as a 3D current collector for high-loading conversion or alloy-type anodes, accommodating large volumetric expansion during cycling without electrode pulverization.
Water Electrolyzers (AEMWE & Alkaline Water Electrolysis): Ni-Fe foam is considered a benchmark electrocatalyst substrate for the Oxygen Evolution Reaction (OER) in alkaline media: (1) Intrinsic Synergistic Catalysis: Incorporating Fe(3+) into the Ni(OH)2/NiOOH lattice optimizes the adsorption energy of oxygen intermediates (O*, OH*, OOH*), lowering OER overpotential to ~ 200–250 mV at 10 mA/cm2. (2) 3D Bubble Detachment: The open reticulated strut structure facilitates micro-bubble release (O2 and H2), suppressing gas-film blockage and mass-transport overpotential at high operating current densities (>1 A/cm2).
Solid Oxide Fuel Cells (SOFC) & Solid Oxide Electrolysis Cells (SOEC): Ni-Fe alloy foams matching the thermal expansion coefficient (TEC) of ceramic electrolytes serve as porous current collectors and gas distribution layers on the fuel (reducing) side.
