| Use advice for data set | When using this dataset for Life Cycle Assessment (LCA), users should ensure that the system boundary includes pre-treatment dismantling and discharging. The functional unit must be clearly defined as the recycling of a 1 kWh NCM battery weighing 0.81kg. Attention should be given to the quality of recovered materials and potential losses during recycling. Users need to consider the technological applicability of the recycled materials in their specific context and the environmental impacts associated with the recovery process, including energy consumption and emissions. |
| Technical purpose of product or process | The pyrometallurgical-hydrometallurgical combined recycling process is intended for the recovery of cathode materials from spent lithium ternary (NCM) batteries. This technology is utilized in recycling facilities to reclaim valuable metal elements through high-temperature smelting, leaching, and high-temperature sintering, thus contributing to the circular economy in the battery industry. The resulting purified materials can be used to manufacture new battery cathodes, supporting the sustainable lifecycle of lithium batteries. |

| General comment on data set | After simple pre-treatment dismantling and discharging, the waste lithium ternary battery system is subjected to high-temperature melting, leaching and oxidizing, and high-temperature sintering to produce battery cathode materials again. The process is mainly the product of the fire recovery technology to further use wet purification, so that both the requirements of the reaction object is lower, but also can reduce the waste of metal elements. |
