| Use advice for data set | This dataset is intended for life cycle assessment practitioners assessing the environmental impact of battery recycling processes. When using the data, ensure to consider the simplified disassembly and discharge stage of the waste lithium batteries prior to the high-temperature smelting process. Inclusion or exclusion of the energy and emissions associated with the smelting operation and the subsequent separation and refining of metals should be critically evaluated. It is also essential to account for the fate of metals like aluminum, lithium, and others that enter the slag, their potential environmental impacts, and any considerations for slag processing or disposal. |
| Technical purpose of product or process | The pyrometallurgical technology for ternary lithium batteries described in this dataset is used in the recycling of waste lithium-ion batteries (LIBs). The recycling process primarily allows for the recovery of valuable metals such as cobalt, nickel, and copper, which are typically found in ternary lithium batteries. These recycled metals are used for the production of new battery cells and other industrial applications where high-purity metal alloys are required. |

| General comment on data set | Pyrometallurgical recycling only requires simple disassembly and discharge of the waste LIBs and direct hightemperature smelting. Cobalt, nickel, copper, and other metal alloys are obtained by adding slag forming agent and reducing agent, while aluminum, lithium, and other metal elements enter the slag. |

| Technology description including background system | The organic binder is removed by calcination, the lithium iron phosphate powder is separated from the aluminum foil, and the lithium iron phosphate material is obtained, and then an appropriate amount of raw material is added to it to obtain the required molar ratio of lithium, iron and phosphorus, and a new lithium iron phosphate is synthesized by high temperature solid phase method. |
