This is a market dataset, representing the consumption market of the region. The dataset includes transport from the gate to the point of consumption, and transport services are calculated based on the transport situation of this product in the region. Nickel cobalt manganese (NCM811) oxide can be used as the positive electrode active material for ternary lithium-ion batteries; this dataset includes main raw materials, auxiliaries, energy, atmospheric emissions, and waste generated during the production process, but infrastructure such as the manufacture of production equipment and construction of buildings is not included in the boundary of this dataset; the data inventory is formed by aggregating data from multiple sources; NCM811 oxide is produced through a multi-step calcination process, with NCM811 hydroxide and lithium hydroxide undergoing two or three rounds of mixing and sintering in the calcination kiln. The resulting material is then crushed, sieved, and demagnetized to obtain the NCM811 oxide. The general reaction is as follows: NMC(OH)2 + 2LiOH→Li-NMC-O2 + 2H2O.
