Molecular Engineering of Ion-Conductive Polymer Membranes for Advanced Batteries (PhD Position)

This PhD position at Imperial College London is part of the Centre for Doctoral Training in Green Industrial Futures (CDT-GIF), a collaborative programme funded by the UK Engineering and Physical Sciences Research Council and supported by leading universities and industrial partners. The project focuses on the molecular engineering of ion-conductive polymer membranes for advanced battery technologies, with a particular emphasis on sodium and lithium batteries. The research aims to tailor polymer backbones, side chains, and ionic functionalities to achieve high ionic conductivity, electrochemical stability, and dendrite suppression, contributing to safer, higher-energy-density, and more sustainable battery systems. As a PhD researcher, you will engage in polymer synthesis, membrane fabrication, advanced electrochemical and materials characterisation, and fundamental transport modelling. The project is associated with the prestigious ERC Consolidator Grant IonPATH, ensuring access to a well-resourced and intellectually stimulating research environment. You will receive interdisciplinary training at the interface of synthetic chemistry, materials science, electrochemistry, and chemical engineering. The CDT-GIF programme offers a four-year research project starting in September 2026, including residential taught courses at partner universities, training in life cycle analysis, technoeconomics, business models, policy and regulation, public engagement, and plant operation. Additional opportunities include international placements, work experience with industrial partners, and participation in a bespoke net-zero leadership programme with regular exchanges, industry challenge sandpits, site visits, and professional development activities. Applicants should hold or expect to obtain a strong first-class or upper second-class degree in Chemistry, Chemical Engineering, Materials Science, Physics, or a closely related discipline. A solid background in polymer science, electrochemistry, membrane science, or energy materials is highly desirable. Prior research experience in polymer synthesis, materials characterisation, or electrochemical testing of batteries or electrolytes will be an advantage. Candidates must demonstrate strong analytical and problem-solving skills, the ability to work independently and as part of a multidisciplinary team, and excellent written and verbal communication skills in English. Motivation to work on fundamental and applied research in sustainable energy storage materials is essential. Funding includes full UK fees, a tax-free stipend (£20,780 for 2025/2026 plus around £2,000 London weighting), and a budget for travel and consumables. Applications are accepted year-round.
