Nickel cobalt manganese (NCM622) lithium hydroxide is a chemical precursor of the cathode active material in lithium-ion batteries; this dataset includes primary raw materials, utilities, and wastewater treatment involved in the production process, while infrastructure such as production equipment manufacturing and plant construction are not within the boundary of this dataset; the data inventory is formed by consolidating data from multiple sources; the synthesis of the ternary precursor adopts a co-precipitation method, using nickel salt, cobalt salt, and manganese salt as raw materials, which are mixed in a certain ratio and then reacted with a precipitant (such as sodium hydroxide, etc.) under certain conditions to produce a ternary precursor precipitate, which is then washed, filtered, dried to obtain the ternary precursor. powder.
