Between, seriously affect production efficiency.So need to work out a kind of can quickly judge what whether box hat nickel coating was totally disrupted
Method.
The box hat of lithium ion battery is that iron and carbon collectively constitute, and in wet environment, surface is because of suction-operated meeting
It covers the faint ionization of one layer of very thin moisture film, water and generates a small amount of H+And OH-, it is molten that such box hat surface can form one layer of electrolyte
Liquid film, iron and carbon inside box hat are formed countless small primary batteries, and wherein iron is cathode, and carbon is anode.So
Box hat corrosion in wet environment is not simple chemical reaction, but a kind of electrochemical reaction.In order to promote this electrochemistry
The progress of reaction can increase the ion concentration of electrolyte solution, accelerate ionic conduction, this direction can pass through saline sook
It realizes.But because brine is neutral, wherein OH-Ion concentration is not high, and the reaction of Fe is slower, so needing constantly to absorb
Oxygen is dissolved in water in air, forms OH-, can effectively realize the corrosion of box hat.In conclusion box hat Accelerated corrosion,
It needs to possess high humidity simultaneously, oxygen comes into contact in a large area and higher three aspects of salinity.So box hat is placed on salt fog ring
It can fast and effectively test whether box hat plating nickel on surface layer is totally disrupted in border.
