Background technique
The electrolyte of one of important composition ingredient in lithium ion battery is the organic solution of lithium hexafluoro phosphate, hexafluorophosphoric acid
Lithium can decompose generation hydrofluoric acid when encountering moisture, have serious corrosivity to steel, this is a big characteristic of electrolyte,
It is lithium ion battery producer after lithium ion battery liquid injection sealing, the big problem faced about battery appearance.
Lithium ion battery requires surface that cannot generate corrosion by electrolytic corrosion in use, and otherwise battery is using
In the process because corrosion is gradually deepened so as to cause battery leakage, and then generate the safety accidents such as on fire or explosion.For guarantee lithium from
Sub- battery steel shell is not corroded because of electrolytic corrosion, and steel shell can plate the nickel plating of 3~5um thickness on its surface layer in process of production
Layer will not be by electrolytic corrosion, to guarantee that lithium ion battery appearance is good because the chemical property of nickel is stablized, non-corroding trace
Mark.

Work step is likely to result in the destruction of steel shell surface layer nickel coating, and whether employee can not be by visually determining these work steps by nickel plating
Layer destroys completely, and battery is placed on detected in wet environment nickel coating whether destroy needs one day or one day or more when
Between, seriously affect production efficiency.So needing to develop one kind can quickly determine what whether steel shell nickel coating was totally disrupted
Method.
The steel shell 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 steel shell surface will form one layer of electrolyte
Liquid film, iron and carbon inside steel shell are formed countless small primary batteries, and wherein iron is cathode, and carbon is anode.So
Steel shell in wet environment corrodes not simple chemical reaction, 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 be impregnated by salt water
It realizes.But because salt water is neutral, wherein OH-Ion concentration is not high, and the reaction of Fe is slower, so needing continuous absorb
Oxygen is dissolved in water in air, forms OH-, can effectively realize the corrosion of steel shell.In conclusion steel shell Accelerated corrosion,
Need to possess simultaneously high humidity, oxygen comes into contact in a large area and three aspects of higher salinity.So steel shell is placed on salt fog ring
It can fast and effectively test whether steel shell plating nickel on surface layer is totally disrupted in border.
