The application of nickel in the battery field is mainly nickel foam, nickel storage alloy, ball nickel and ternary materials. Among them, the amount of nickel foam, nickel storage alloy and ball nickel has been kept at a relatively stable level every year, and the amount of ternary materials has been increasing year by year since 2010. During the period of global electrification rapid development in 2014-2016, nickel was in ternary materials. The amount of use has also seen rapid growth. At present, ternary materials have become the main application of nickel in the field of batteries.
