The BATTRACE project – Sustainable processing and traceability of battery metals, minerals, and materials – was run 1.5.2020−31.10.2023. The public part of the research was conducted by the research institutes VTT and GTK and the main outcomes of the work were summarized in this book. GTK focused on developing analytical methods for tracing battery raw materials and assessing related business models. Global traceability practices were identified and evidence-based forensic traceability methods for battery metals and raw materials based on geological fingerprinting were developed. VTT's focus on the project was on the development of direct battery metal production and on battery precursor materials. Direct production of metal sulphates without intermediate products has the potential to simplify process flowsheets.The in situ or semi in situ chord length tracking method could be used for monitoring precursor co-precipitation either in the batch or continuous precursor process.<br/>
