About this position
This four-year PhD will develop sustainable biochar-based porous carbon electrodes for low-carbon sodium-ion batteries, addressing the need for scalable energy-storage technologies that reduce dependence on critical raw materials.
The researcher will produce biochar from selected biomass residues using controlled pyrolysis, then tailor its pore structure and surface chemistry for sodium-ion storage. The project will examine how biomass type, pyrolysis conditions and post-treatment affect electrode performance, degradation and lifetime when biochar is used as an anode or conductive scaffold.
Research activities will combine biomass conversion, porous-carbon synthesis, electrochemistry and degradation science. The student will use materials-characterisation techniques including BET, SEM/TEM, XRD, Raman spectroscopy and surface analysis, alongside electrode fabrication, sodium-ion half-cell testing, galvanostatic cycling and periodic electrochemical impedance spectroscopy. Results will be benchmarked against conventional hard-carbon anodes.
A key focus is understanding structure–property–degradation relationships under realistic cycling. The project will also assess the carbon balance and net-zero relevance of biochar electrodes through high-level lifecycle and carbon-impact analysis, linking the work to grid-scale storage, circular-economy energy systems and bio-integrated energy technologies.
The researcher will join the EPSRC and BBSRC Net2Zero Centre for Doctoral Training, a partnership involving Aston University, the University of Nottingham, Queen’s University Belfast and the University of Warwick. The CDT provides interdisciplinary research training, access to advanced facilities, collaboration with academia, industry and policymakers, and the opportunity for a three-month external placement. Supervisors are Dr Volkan Degirmenci and Professor Evgeny Rebrov.

What's required
Applicants need a strong foundation in Chemical Engineering, Materials Science, Chemistry, or a related discipline, with a First or Upper Second-Class honours degree or equivalent overseas qualification, and a strong interest in sustainable energy and materials. Experience with electrochemistry or materials characterisation and familiarity with porous materials, carbon materials or batteries are desirable. Applicants must qualify for UK home fee status; international candidates will not be considered. If English is not the applicant’s first language, evidence of meeting the English language requirements is required, although it may be submitted at a later stage. Applicants must provide academic transcripts and certificates, passport documentation and information about their research background and experience.
How to apply
Submit an Expression of Interest through the Google Forms application link, including personal details, passport and status evidence where relevant, degree transcripts and certificates, personal characteristics information, English-language evidence if applicable, and research background and experience. Shortlisted candidates may meet the potential supervisors before submitting a formal application to the relevant home institution.
