The Department of Energy Conversion and Storage (DTU Energy) Organisation/Company Danmarks Tekniske Universitet Department The Department of Energy Conversion and Storage (DTU Energy) Research Field Physics Engineering » Chemical engineering Chemistry Researcher Profile First Stage Researcher (R1) Positions PhD Positions Country Denmark Application Deadline 30 Nov 2025 - 12:00 (Europe/Copenhagen) Type of Contract Temporary Job Status Full-time Offer Starting Date 1 Apr 2026 Is the job funded through the EU Research Framework Programme? Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? No Offer Description We are looking for a motivated and creative candidate to fill a position as a PhD student as part of the MSCA Doctoral Network “SPACER” (Shaping Porous Electrode Architecture to Improve Current Density and Energy Efficiency in Redox Flow Batteries). SPACER aims to develop new architectures for porous electrodes to improve the power density and energy efficiency of redox flow batteries (RFB), enabling affordable and durable long‑duration energy storage. The approach is to use hierarchical structures, i.e., complex material layers that can be optimized to specific battery chemistries and flow phenomena from the microscale up. The developed technologies will be validated in half‑cells and full working batteries at industrial partners at TRL 6. Responsibilities and qualifications Your task will be to use electrochemical impedance spectroscopy and other complimentary characterisation techniques to provide holistic and detailed performance characterisation of new hierarchical porous carbon electrodes developed in the network. You will leverage advanced data analysis methods such as Distribution of Diffusion Times to obtain insight into mass transfer and microstructural effects in the new generation of electrodes. The project will be carried out in collaboration with network partners, requiring 3-6 months of secondments abroad. You will have the opportunity to work as part of an international, interdisciplinary team of 17 doctoral candidates, based at universities and industrial firms throughout Europe. You will be supported by two mentors within the SPACER project and will have multiple opportunities to participate in professional and personal development training. Through your work you will gain a unique skill set at the interface between modelling and prototyping of electrode materials, including characterization of electrodes using spectroscopical and electrochemical techniques at different levels from micro‑scale to macro‑scale. You are expected to finish the project with a PhD thesis and to disseminate the results through patents (if applicable), publications in peer‑reviewed journals, and presentations at international conferences. In accordance with the European Union’s funding rules for doctoral networks, applicants must NOT yet have a PhD. You must have: A Master’s degree and/or BSc degrees in Chemical Engineering, Physics, Chemistry, Materials Science, or related disciplines. An aptitude for experimental research and data analysis. Excellent written and oral communication skills in English are prerequisites. Additionally, experience with programming and/or mathematical modelling is an advantage. Due to the MSCA mobility requirement, you must not have resided or carried out your main activity (work, studies etc.) in Denmark for more than 12 months in the past 3 years. You must have a two‑year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two‑year master's degree. Approval and Enrolment Approval and Enrolment The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education.
