On 28 February 2025, one of our partners, MSc. Jere Partinen, successfully defended his doctoral thesis in Chemical Engineering at Aalto University. The public examination focused on his research "Leaching of lithium-ion battery materials in sulfate and chloride media for hydrometallurgical recycling".
The official public examination of the doctoral thesis allowed for an in-depth discussion on the research findings related to hydrometallurgical recycling methods for lithium-ion batteries within the RESPECT project.
The defence began with a 20-minute presentation by Jere Partinen, summarising the key aspects of his thesis. This was followed by a detailed discussion led by the External Examiner, Associate Professor Sulakit Bandyopadhyay from the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. The discussions explored the scientific and industrial implications of lithium-ion battery leaching in sulfate and chloride media.
The research examined leaching processes applied to both commercially available battery cathode chemicals and industrially processed battery waste, known as black mass. The study provided insight into the reaction mechanisms of battery cathode materials in sulfuric and hydrochloric acid solutions. Additionally, findings highlighted the role of metallic copper (Cu) and aluminum (Al), originating from battery current collectors, as effective reductants in the leaching process.
Findings from the RESPECT project (WP3) were shared through the thesis presentation and subsequent discussions. Attendees had access to a summary of related research papers, available both as physical copies and as downloadable PDFs for online participants.
The defence successfully showcased the significant contributions of the RESPECT project to both academic research and industrial applications. By providing detailed insights into black mass leaching mechanisms, the work supports advancements in sustainable lithium-ion battery recycling processes.
