Data underlying the publication: Simultaneous Recycling of Spent LiFePO4 and LiNixMnyCozO2 Li‑Ion Batteries Under Mild Leaching Conditions

Data underlying the publication: Simultaneous Recycling of Spent LiFePO4 and LiNixMnyCozO2 Li‑Ion Batteries Under Mild Leaching ConditionsThe purpose of the experiments was to study the chemical composition of various spent Li-ion batteries from consumer e-waste. Then, different types of waste were submitted to hydrometallurgical leaching together, followed by a pH increase to precipitate the leached metals. Following the hydrometallurgical steps, the residues and precipitates were characterized by XRD-analysis.The data is sorted in folders for each set of figures or each table. The data mainly consists of ICP-OES measurements, which are expressed as the concentration of metals in solution (ppm). These are used to calculate the composition of the feed materials (battery waste, wt.%), leaching efficiencies (%) and precipitation efficiencies (%). These are all in spreadsheet format (.ods). There are also some X-Ray diffraction studies done. These are found as PDF-documents, which contain the X-ray-diffractograms and the peak allocation. From the diffractograms, the present compounds can be identified.

本论文支撑数据集：温和浸出条件下磷酸铁锂（LiFePO4）与镍钴锰酸锂（LiNixMnyCozO2）废旧锂离子电池的协同回收

本实验旨在分析消费电子废弃物中各类废旧锂离子电池的化学成分。随后将不同类型的废旧电池进行协同湿法冶金浸出，再通过调高pH值使浸出得到的金属发生沉淀。湿法冶金流程完成后，采用X射线衍射分析（XRD）对浸出残渣与沉淀物进行表征。

本数据集按文件夹分类，每个文件夹对应一组图表或一张表格。数据集主要包含电感耦合等离子体发射光谱（ICP-OES）测试数据，以溶液中金属的浓度（ppm，百万分比）表示。该数据可用于计算原料（电池废弃物，质量百分比wt.%）的组成、浸出率（%）与沉淀率（%），所有数据均以电子表格格式（.ods）存储。此外还包含部分X射线衍射测试数据，以便携式文档格式（PDF）文件形式提供，文件内包含X射线衍射图谱及峰位归属信息。通过分析衍射图谱，可识别样品中存在的化合物。
