| Use advice for data set | When utilizing the Life Cycle Assessment data set for Process B, users must account for regional disparities; this data set average is based on a literature review and not optimized for individual industries or countries. It does not incorporate recycling or treatment of plastic and metal shells, labor and construction costs, or environmental impacts thereof. For accurate application, supplement with region-specific data, especially in the context of China where EU import/export data and recycling information may not apply. Users should adjust the weight of evidence towards more current and locally relevant data where possible, and be cognizant that the functional unit (FU) is based on 100 kg of a typical LIB electrode material. |
| Technical purpose of product or process | Pyrometallurgy--Carbonthermal reduction (Process B) is an industrial process where reducing carbon is mixed and roasted with valuable compounds in a rotary furnace at high temperatures (600-1000 oC), using graphite as the reducing agent. This method effectively reduces and separates reduction products such as Ni (Nickel), Co (Cobalt), MnO (Manganese Oxide), and allows for the selective recovery of lithium resources in the form of Li2CO3 through water leaching. It is commonly applied in the production of LIB (Lithium-ion Battery) electrode materials and is crucial for the recycling and valorization of metals from spent LIBs. |
