Abstract:Continuous nickel foam became the ideal material of electrode plate of MH/Ni and Cd/Ni battery, because of its excellent three-dimensional reticulated structure, high porosity, high specific surface area and uniform quality, and was widely used in many other fields. This paper described the production technique of continuous nickel foam. It includes technique of conductive treatment methods, nickel electrodesposition, pyrolysis and reduction. Through comparison of conductive colloid coating, vacuum vapor phase deposition and electroless nickel, the advantages and disadvantages of different methods of conductive treatment were shown. Moreover, production methods and equipments of continuous nickel foam of main manufacturers were introduced. Meanwhile, performance figures and evaluation means of continuous nickel foam used in MH/Ni or Cd/Ni were emphatic given, and spacious market outlook and development direction was previewed.
Key words: nickel foam; electrode; conductive treatment; electrodeposition
