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. The energy density of the NCM811 cell is approximately 240Wh/kg; this dataset includes the main raw materials, auxiliary materials, energy, atmospheric emissions, and waste from the production process. The production equipment manufacturing, plant construction, and other infrastructure are not included within the boundaries of the dataset; the data inventory is formed by merging data from multiple sources, and supplementary improvements have been made on the data of gas emissions (VOCs), water emissions (cobalt, COD), and waste referring to industry statistics, standards, pollutant discharge coefficient manuals, etc.; the production of NCM811 cells includes slurry preparation (mixing of electrode materials, conductive agents, binders, and solvents), electrode sheet preparation  (coating, drying, rolling, slitting), cell assembly, welding and packaging, electrolyte filling and sealing, charging, shaping, sorting, aging, testing, etc.
