The energy density of the NCM811 cell is approximately 240Wh/kg; this dataset includes major raw materials, auxiliary materials, energy, atmospheric emissions, and waste from the production process. Manufacturing equipment, facility construction, and other infrastructure are not included within the boundaries of the dataset; the data inventory is compiled from multiple sources and, with reference to industry statistics, standards, and emission coefficient manuals, the data for gas emissions (VOCs), water emissions (cobalt, COD), and waste has been supplemented and refined; the production of the NCM811 cell includes the preparation of the slurry (electrode material, conductive agent, binder, and solvent mix) and the preparation of the electrode plates. (coating, drying, rolling, slitting), cell assembly, welding and packaging, electrolyte filling and edge sealing, charging, forming, grading, aging, testing, etc.
