Beschreibung
Zusammenfassung:	The invention relates to the field of nitrogen trifluoride preparation, in particular to a preparation method of a foamed nickel anode for preparing nitrogen trifluoride through an electrolytic method. The method comprises the following steps: 1, conducting a base material; the method comprises the following steps: selecting plate-shaped polyurethane sponge as a base material, and plating nickel on the base material or dip-coating conductive adhesive to enable the base material to be conductive; 2, electroplating; electroplating by taking the conductive base material as a cathode, pure nickel as an anode and electrolyte as a nickel salt solution to obtain electroplated foamed nickel; 3, removing the mold; and the electroplated foamed nickel is subjected to heat treatment, the base material is removed, and then reduction is conducted. The plate-shaped polyurethane foam is used as a base material, then nickel plating treatment is performed on the base material, and finally demolding is performed, so that the ob
