As the method of coating Ni for battery cases, there are two meth- ods: coating the entire case after forming and coating a coiled sheet before forming.
The battery manufacturing process is a complex sequence of steps transforming raw materials into functional, reliable energy storage units. This guide covers the entire process, from material selection to the final product’s assembly and testing.
Due to the urgent nickel sulfate demand in the battery field, a short-term solution can be to refine nickel sulfate products from nickel intermediates. In the long term, novel direct battery grade nickel sulfate technologies are needed.
Pyrometallurgical processes for nickel extraction are energy intensive , the by-product metals are mostly lost, and the process is sensitive to pyrrhotite which is a common gangue mineral in magmatic nickel sulfide deposits .
The direct nickel process is designed to consist of chemical leaching, impurity removal by precipitation, solvent extraction, and crystallization. The process concept development is done based on modeling with the HSC-Sim chemistry software.
Nickel for the Li-ion batteries must be in the form of nickel sulfate (NiSO 4 ·6H 2 O), which is a niche product from class I nickel . Conventionally, nickel sulfate is produced from intermediate or refined nickel products, which have been further directed to additional metallurgical processes to attract a premium price .
