Abstract: The process conditions in the electrodeposition of nickel foil were studied. The SEM morphology of the surface and section of nickel foil was observed and associated with tensile strength. The results showed that the limiting current density could be greatly increased by dynamic electrodeposition. When the flow velocity was about 1.2 m/s the limiting current density reached 0.9 A/cm2. The SEM morphology showed that the grain size of nickel foil by dynamic electrodeposition was less than that by static condition. The grain size was decreased to about 1 μm. The section morphology showed that the crystal size of pure nickel foil grew gradually along the direction of thickness during electrodeposition. When adding additive, the surface of nickel foil was much brighter. The tensile strength was greatly increased when adding 5 g/L saccharin. The maximum tensile strength could reach 900 MPa.
