When it comes to nickel sulphate, there are two main markets to avoid: electroplating and batteries. Correspondingly, there are two main divisions of nickel sulphate: electroplating nickel sulphate and battery nickel sulphate. The following is a brief analysis of my personal understanding of the limitations of electroplating grade and battery grade nickel sulphate.
First, the two quality requirements are different
1. Nickel sulphate of electroplating grade has requirements for cobalt Co elements. Generally, the lower cobalt is within 0.05% or the lower the better, where cobalt is a harmful element. Battery grade nickel sulphate is generally not required for cobalt Co element, because cobalt is one of the main elements in nickel cobalt manganese lithium battery.
2. At present, battery grade nickel sulphuric acid has been required for fer.zn.cr and other magnetic foreign substances, while electroplate grade nickel sulphuric acid has no requirements for this.
3. There is no clear data requirement for various indexes of electroplating grade nickel sulphate, so as to meet the specific use. (not high requirements, but no specific data level requirements) but the basic use of jinchuan, jean, jinke production electroplating grade nickel sulphate. Battery material manufacturers, by contrast, have clear specifications for battery grade nickel sulphate. The nickel sulphate that meets the index requirement, can use basically.
2. The two sell in different ways
Electroplating plants tend to be small and numerous (several are said to have 15,000 in China), and the demand for nickel sulphate is not large. Purchase on demand. As a result, nickel sulphate producers do not have enough energy to deal with zero orders from electroplating plants. So the electroplating grade nickel sulphate market has the dealer or the agent this important role existence. Plating nickel sulfate manufacturers docking distributors or agents (of course, there are large electroplating factory), and then by the distributor or agent in all major regions or scattered distribution or agent for the sale to electroplating factory.
Under the battery-grade nickel sulphate market, the demand of nickel sulphate is large and relatively concentrated in the major battery material factories. From the nickel sulphate producer directly to the nickel sulphate demand users, no intermediary exists.
Iii. Personal understanding of the author
Electroplating technology is complex, each has its own electroplating formulations. Matching various properties of electroplating nickel sulphate, the company has developed its own electroplating process and operation line, and will not adjust the supplier of electroplating nickel sulphate easily. The reasons are as follows: electroplating plants have a high demand for comprehensive stability of nickel sulphate suppliers, which requires stable production, stable supply quantity and stable quality. The cost of changing process and production line of electroplating factory is too high, the influence is too big, still have the possibility to affect the product. Based on the above situation, electroplating nickel sulfate supplies must be stable, the quality must be stable, word of mouth reputation is outstanding, the performance ability stronger, can sign the supply long association, by means of this brush to choose qualified plating nickel sulfate supplier, basic is known.
However, the battery grade nickel sulphate market, although there are clear and strict requirements on quality, is also due to specific requirements, the demand is huge. So that the nickel sulphate suppliers according to the target production, can basically achieve the intention of supply cooperation.
