Advance innovative electrochemical recycling of lithium iron phosphate batteries. Join this collaborative 10-month Postdoc project and help accelerate the transition to a circular battery value chain by recovering critical raw materials through cutting‑edge electrochemical research in close partnership with industry.
Job descriptionBatteries will play a crucial role in the transition from fossil fuels to a more sustainable world based on renewables. Lithium‑ion batteries (LIBs) are used in many consumer products (e.g., toys, and electric cars) due to their high energy density. The LIB market is expected to grow exponentially the coming decades due to the electrification of the society. Between now and 2030, it has been estimated that around 11 million metric tons of LIBs will reach the end of their lives. Worldwide, less than 5 % of all LIBs are currently recycled, which means that 95 % of the spent batteries are landfilled with a serious risk for the health and environment. LIBs contain large amounts of critical raw materials like cobalt, lithium, and nickel, which should be recycled and not wasted.
In this project, you will advance electrochemical recycling technologies and translate laboratory innovation into scalable solutions. You will:
- Design and optimise electrochemical recycling processes (specifically: electrodialysis and flow capacitive deionization) to selectively recover lithium and other valuable metals from LFP battery leachates.
- Develop and test new materials and cell configurations, improving extraction efficiency, selectivity and energy performance.
- Adapt and enhance laboratory‑scale electrochemical setups to generate robust experimental data on process stability, efficiency and energy consumption.
- Evaluate and quantify the technical and economic feasibility of the developed processes through a techno‑economic analysis, identifying pathways toward scale‑up and industrial implementation.
- Collaborate and communicate with industrial partners and academic colleagues, ensuring alignment with project deliverables and translating scientific insights into practical recycling strategies.
You will work in close collaboration with industry partners and contribute to scientific publications and knowledge dissemination. Through this role, you directly support the transition to a circular battery economy by developing technologies that reduce waste, recover critical materials and lower the environmental footprint of energy storage systems.
Process & Energy – Engineering Thermodynamics GroupYou will be part of the Engineering Thermodynamics group within the Process & Energy Department at TU Delft and will work under guidance of Dr. Mahinder Ramdin. The group focuses on understanding and modelling the thermodynamic behaviour of fluids and mixtures to enable efficient, reliable and sustainable energy and process technologies. By combining molecular‑level theories, advanced equations of state and computational modelling, the team investigates phase equilibria, transport properties and complex fluid behaviour relevant to applications such as carbon capture, hydrogen systems, geothermal energy and advanced separation processes.
Within the Engineering Thermodynamics group, you will work in a collaborative and international research environment, closely connected to partners across academia and industry. You will contribute to the development of predictive thermodynamic models and simulation tools that underpin next‑generation energy systems and circular chemical processes. The group values scientific interaction, intellectual curiosity and open collaboration, offering you the opportunity to strengthen your analytical and computational expertise.

- As part of knowledge security, TU Delft conducts a risk assessment during the recruitment of personnel. We do this, among other things, to prevent the unwanted transfer of sensitive knowledge and technology. The assessment is based on information provided by the candidates themselves, such as their motivation letter and CV, and takes place at the final stages of the selection process. When the outcome of the assessment is negative, the candidate will be informed. The processing of personal data in the context of the risk assessment is carried out on the legal basis of the GDPR: performing a public task in the public interest.
