Nickel matte
Nickel matte is an intermediate product of nickel extraction, a mixture of nickel sulfides produced by smelting and refined into Class 1 nickel metal or nickel sulfate.
Nickel-rich cathode
A nickel-rich cathode is a layered oxide positive electrode for lithium-ion batteries, typically NCM or NCA, where nickel content above 80% raises energy density while reducing costly cobalt.
Nickel-rich NCM 811 cathodes
