Nickel cobalt manganese (NCM523) oxide can be used as the cathode active material of ternary lithium-ion batteries; this dataset includes primary raw materials, auxiliary materials, energy, atmospheric emissions, and wastes in the production process, but infrastructure such as the manufacturing of production equipment and construction of buildings is out of the boundary of the dataset; the data inventory is formed by merging data from multiple sources; NCM523 oxide is manufactured by a multistep calcination process that involves two or three rounds of mixing and sintering of NCM523 hydroxide and lithium carbonate in a calcination kiln, the resulting material is then pulverized, sieved, and demagnetized, yielding NCM523 oxide.
