| Use advice for data set | Users should apply this data set considering the specific end-of-life scenario for ternary lithium batteries, taking into account the energy consumption expressed in GEB2016 (12.0 × 1024 sej) per 1 kWh of battery output. The data should be used to model the environmental impacts of the hydrometallurgy process accurately. It is important to consider the completeness of the data from various papers and ensure methodological alignment with the functional unit of 1 kWh during the life cycle assessment. |
| Technical purpose of product or process | The advanced hydrometallurgy process for ternary lithium batteries described is utilized in the recycling of end-of-life (EoL) battery materials. Specifically, it is used to recover high-purity lithium carbonate, which is a critical component in the manufacture of new battery cells for consumer electronics, electric vehicles, and energy storage systems. |

| General comment on data set | Before adopting the wet process for material recovery, the EoL ternary lithium batteries are safely discharged, disassembled, pyrolyzed, mechanically crushed, and sorted to get powdered lithium-containing waste. Lithium-containing material is added to leaching solvent for leaching, filtered and separated to get lithium-containing solution, added to the purification agent for reaction, filtered, concentrated, and under certain reaction conditions, added to the precipitation agent fully reacted to crystallization and precipitation, filtered, washed and dried to get battery-grade lithium carbonate.Translated with DeepL |

| Technology description including background system | Leaching: During the leaching process, the solid-liquid ratio of the selected electrode materials for smelting and the leaching solution should be controlled within the appropriate range, and should be stirred evenly and reacted adequately.Impurity removal: The impurity removal process should be based on the premise of not introducing excess impurities, combined with precipitation and extraction methods to ensure that the impurity elements are reasonably removed, and reduce the loss of nickel, cobalt, manganese, lithium and other elements.Purification: Should be purified according to the characteristics of metal elements, select the appropriate extractant, under certain extraction conditions, after multiple extraction, to obtain a high-purity target metal solution, such as nickel, cobalt, manganese solution or lithium solution.Material synthesis: Material synthesis is the process of converting metal purification liquid into positive electrode materials, precursors and other battery materials. The products synthesized by the material should meet the national standards or industry standards of the relevant products, nickel diamond lithium manganese oxide should meet the requirements of YS/T798, nickel cobalt manganese hydroxide should meet the requirements of GB/T26300. |
