Join us to shape the future of battery recycling by developing electrified technologies that recover high-purity materials from complex Li-ion streams and close the materials loop
Job descriptionJoin the Materials Production, Refining and Recycling (MPRR) group in the Department of Materials Science and Engineering (MSE) at TU Delft, in collaboration with the Netherlands Organisation for Applied Scientific Research (TNO), to contribute to advancing Li-ion battery circularity by developing innovative methods to electrochemical the purification and separation of various elements from mixed NMC and LFP Li-ion battery waste streams.
The project will be jointly supervised by Dr. Shoshan Abrahami (TU Delft) and Dr. Devin Boom (TNO), and is part of the ADAPT-BATT (Adaptive Processing for LFP-mixed Battery Waste Streams) project. ADAPT-BATT is embedded within the national Material Independence & Circular Batteries program, which supports the growth of the Li-ion battery manufacturing and recycling industry in the Netherlands.
As a PhD researcher, you will:
- Optimize the leaching of desired elements from mixed battery waste streams.
- Develop sustainable processes to electrify the purification and separation methods of Cu, Al, Fe, graphite from the leach solution.
- Optimize cell design and closed loop operation.
- Evaluate the performance of recycled materials in new battery cells.
Your work will contribute to recycling routes that use fewer chemicals, reduce waste, and lower greenhouse gas emissions compared to conventional recycling processes.
Background
Batteries are essential for decarbonizing transport and enabling renewable energy storage, yet their widespread use presents a growing waste-management challenge. Recycling spent batteries is key to recovering valuable materials and improving the sustainability of the battery value chain. Hydrometallurgical recycling is especially well-suited for processing the complex and variable composition of industrial Li-ion battery waste streams, including LFP chemistries. However, to meet EU regulatory targets and reduce environmental impact, these processes must become more efficient and selective to enable high purity recovery and improved recovery rates.
Job requirementsWe are seeking a proactive, self-motivated candidate with a strong background in experimental research. Candidates should meet the following requirements:
- MSc degree in Materials Science, Metallurgy, Chemistry, or a closely related field.
- Practical experience in hydrometallurgy and electrochemistry. Previous work on lithium battery recycling in a plus.
- Proven hands-on experience working in a chemical laboratory and strong knowledge of safety procedures and risk management practices.
- Solid understanding of chemical reactions and thermodynamics. Strong communication skills in English, including proficiency in scientific writing (reports, papers) and technical presentations. TU Delft requires a certain level of English proficiency for participation in Doctoral Education courses and for writing the PhD thesis and scientific publications. Please consult the Graduate School's Admission Requirements for details.
- Ability to work effectively in a team and willingness to collaborate with project partners, including academic and industry stakeholders.

Faculty Mechanical EngineeringFrom chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.
ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It's a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME's outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
