2024-01-05 18:00:06

The existing nickel foil preparation methods mainly include calendering method (mechanical method), hydroxyl method (chemical method) and deposition method (electrolytic method), while the preparation methods of ultra-thin nickel foil below 0.05mm are mainly hydroxyl method and deposition method.

CN108103533A publicly, for example, a kind of the electrodeposition of nickel foil prepared by the technique, with nickel plate as anode, titanium rotating cylinder as cathode, control the temperature of the electric tank plating solution is 50 ~ 60 ℃, control current is 15 ~ 20 a/dm2, and adjusting the ph of the plating solution was 2.5 ~ 3.0, the cathode roller speed is 1.2 ~ 1.4 m/min, production of pure nickel foil width of 1350 mm, the minimum thickness of 5 microns. CN102719801A discloses a process for nickel foil preparation by hydroxyl group method. The preparation process USES nickel-containing water-quenched alloy as raw material, and carbonylation reaction with carbon monoxide gas in the synthesis kettle to prepare carbonyl nickel gas. Then the carbonyl nickel gas was decomposed in the resolver, the decomposed nickel was deposited on the substrate suspended in the middle of the resolver, and the nickel foil was obtained by cooling, kettle discharge and stripping, with the thinnest specification up to 0.02mm. Although the electrolysis method has the advantages of simple equipment, low energy consumption, low emission and recyclable raw materials, the production process is complex, the production cost is high, the efficiency is low, and the environment has a great impact. Although the production efficiency of hydroxyl method is high, the hydroxylation process requires higher production technology and equipment, and it is easy to cause gas leakage and environmental pollution.


If ultra-thin pure nickel N6 foil materials below 0.05mm can be produced by calendering and mass production can be realized, not only can the production efficiency be greatly improved and the production cost be reduced, so as to meet the industrial demand, but also can reduce the environmental pollution, with significant social and economic benefits.
