NMC 811 Battery Raw Materials Nickel Manganese Cobalt Oxide NMC Cathode Raw Material Lithium Ion Batteries Production
Nickel-cobalt-manganese hydroxide is the precursor of lithium nickel-cobalt-manganate cathode material for lithium ion secondary batteries. By adding appropriate manganese sulfate, nickel sulfate or cobalt sulfate into the pure solution of nickel, cobalt and manganese, the molar ratio of nickel, cobalt and manganese elements in the solution is adjusted to 1:1:1, and then the pH is adjusted by adding liquid alkali to obtain nickel, cobalt and manganese hydroxide.
