Nickel sulfate is mainly divided into battery grade nickel sulfate and electroplating grade nickel sulfate.

Battery-grade nickel sulfate is the main source of nickel metal in ternary materials, and is used to prepare lithium nickel cobalt manganate (NCM) and lithium nickel cobalt aluminate (NCA). Since the level of nickel contained in ternary lithium batteries directly determines the charging capacity of the battery, the development of high-nickel ternary lithium batteries is a general trend and will become the second largest area of nickel consumption.

The demand for electroplating grade nickel sulfate is relatively stable, and it is widely used in manufacturing industries such as machines, instruments, meters, medical devices, and household appliances.
