title: Data underlying the PhD Dissertation: "Hydrometallurgical & Electrochemical Recycling of Mixed Li-ion Battery Waste"

description: Data underlying the Dissertation: "Hydrometallurgical & Electrochemical Recycling of Mixed Li-ion Battery Waste"This collection combines the data presented in the 4 experimental chapters (3, 4, 5 and 6) of the respective dissertation. The sorting of the data differs per chapter, and is detailed in the respective readme files.<br>The data from chapter 3 can be found here: https://doi.org/10.4121/de23a97d-b0c7-475a-85fc-b922a7732a15.v1The purpose of these experiments was to characterize different types of Lithium ion battery wastes from consumer electronics, followed by hydrometallurigcal leaching to study the influence of the waste composition on the recycling performance. The data is present as spreadsheet formats (.ods), and contains characterization data by ICP-OES analysis, expressed as metallic concentrations (ppm) and XRD-analysis, expressed as weight percentages.<br>The data from chapter 4 can be found here: https://doi.org/10.4121/fb1d44aa-8d83-44c5-ac6a-f18e6d43a42d.v1The 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.<br>The data from chapter 5 is contained within this dataset. Its purpose was to study electrochemical purification of Lithium ion battery waste by reduction of copper and oxidation of iron impurities. The data is present in spreadsheet format (.ods) and is expressed as elemental concentrations (ppm) in case of aqueous solutions or weight percentages (%) in case of solid materials. The data is sorted per experimental procedure, and the relevant figures and tables are mentioned in the title of the document, as well as in the documents themselves next to the information that is reported in the figures or tables.<br>The data from chapter 6 is also contained within this dataset. Its purpose was to study the influence of acid type on electrochemical purification of Lithium ion battery waste, by reduction of copper and oxidation of iron impurities. Similarly to the data from Chapter 5, the data is present in spreadsheet format (.ods) and is expressed as elemental concentrations (ppm) in case of aqueous solutions or weight percentages (%) in case of solid materials. The data is sorted per experimental procedure, and the relevant figures and tables are mentioned in the title of the document, as well as in the documents themselves next to the information that is reported in the figures or tables.<br>The entire collection of data can be found here:https://doi.org/10.4121/4191a8ac-df4b-4cb3-8caf-bc901e9c892b
