| Use advice for data set | Users of this Life Cycle Assessment (LCA) data set should note that the input-output of Process E is derived from averaged literature review data representing a 'cradle-to-grave' approach within the time frame of 2013-2017. The data excludes considerations of plastic and metal casing recycling or treatment, as well as labor and factory construction costs and their environmental impact. Additionally, users should exercise caution when applying this EU-based data in the Chinese context, as it may not completely align with the industry-specific conditions in China. Modifications using official Chinese data, industry reports, and information from trade associations have been estimated to reflect the data from Chinese stakeholders better. For timeliness, reference the data from the most recent four-year average period available, specifically 2013-2016. Functional unit (FU) reference is based on 100 kg of typical LIB electrode material. |
| Technical purpose of product or process | The hydrometallurgical organic acid leaching process (Process E) uses weak acids such as acetic acid and citric acid along with a reducing agent as the leaching solution. The weak acid selectively leaches valuable metals by reacting with the active materials of the positive electrode while not affecting the aluminum foil collector. This allows for selective recovery and reprocessing of the electrode materials by adjusting the pH and adding metal salts to cause co-precipitation of the valuable metals. This process is applicable in the battery recycling industry, particularly for the regeneration of Lithium-Ion Battery (LIB) electrode materials. |

| General comment on data set | Weak acid (e.g. acetic acid, citric acid, etc.) and reducing agent are used as leaching agent, and the weak acid can react with positive electrode active material without reacting with the aluminum foil of collector, so as to realize selective leaching of valuable metal, and the product can realize electrode active material reproduction by adjusting pH, adding metal salt and so on, so as to cause co-precipitation of valuable metal. |
