Refined nickel can be broadly divided into two main categories based on metal content. Class 1 (nominally pure nickel of >99.8%) and Class 2 (<99.8% purity). However, the amount of nickel in Class 2 products can differ drastically; for example, nickel pig iron (NPI) generally contains less than 5% nickel. Batteries for EVs require Class 1 nickel.
