PhD in Energy Storage in Aqueous Acid-Base Flow Batteries
This PhD position at Eindhoven University of Technology focuses on advancing sustainable energy storage through the development of aqueous acid-base flow batteries. The project is part of a multidisciplinary research team working closely with the industrial partner AquaBattery, aiming to design affordable, safe, and scalable long-duration energy storage systems based on abundant materials. The innovative acid-base flow battery concept has been recognized with the European Sustainable Energy Innovation Award 2025.
As a PhD candidate, you will contribute to the next generation of acid-base flow cells by developing bipolar membranes for enhanced water splitting and recombination, utilizing advanced electrospinning techniques. The research group boasts a unique triple electrospinner, enabling simultaneous electrospinning of anion and cation exchange polymers with a catalyst, creating highly tunable and scalable membrane structures. Your work will involve both fundamental and application-oriented research, with a strong emphasis on scalability for commercial deployment.
The Membrane Materials and Processes group, part of the Department of Chemical Engineering and Chemistry, provides state-of-the-art laboratories and a collaborative environment. The group specializes in the design, development, characterization, and application of polymer membranes for sustainable processes, integrating materials chemistry, engineering, and process technology. Application areas include water and energy, with a focus on energy storage, resource recovery, and waste valorization. You will have access to a wide range of characterization and performance evaluation techniques, and your research will be evaluated in both laboratory and pilot-scale battery systems.
Applicants should have a strong background in chemistry and chemical engineering, with experience in electrochemistry, physical chemistry, and materials engineering. A scientific and research-oriented attitude, hands-on mentality, and interest in industry collaboration are essential. Analytical skills, creativity, and the ability to work in an interdisciplinary team are highly valued. Excellent English communication skills (C1 level) are required, and candidates should enjoy working in an international, social environment. The selection process includes an interview, scientific presentation, and writing assignment.
The position offers full-time employment for four years, with an intermediate assessment after nine months. You will spend 10-15% of your time on teaching tasks. The salary is in accordance with the Collective Labour Agreement for Dutch Universities (scale P: €3,059 - €3,881 per month), plus a year-end bonus, vacation pay, pension scheme, paid parental leave, commuting and internet allowances, and a 30% tax compensation scheme for international candidates. The university provides high-quality training programs, technical infrastructure, on-campus childcare, and sports facilities.
To apply, submit a complete application online including a cover letter, CV with publications and references, and a list of BSc and MSc courses and grades. Only complete applications will be considered, and applications sent by email or post will not be processed. The vacancy will remain open until filled, with a deadline of February 12, 2026.
