We are looking for a doctoral student for the project “Multiscale modelling of ageing mechanisms in lithium-ion batteries”. Charge-discharge cycles of lithium-ion batteries induce swelling and shrinking of electrode materials, generating stresses, cracks, debonding and side reactions, causing capacity and performance loss. It aims to develop a multiscale computational-experimental framework coupling mechanical degradation and ageing across material and cell scales.
Research will be conducted with COMSOL, RISE and Volvo AB, integrating finite-element modelling and experimental validation. At KTH, the focus will be on developing physics-based models capturing mechanical degradation pathways and their influence on electrochemical performance. Experimental validation will be carried out at RISE using advanced dilatational testing, ageing studies under varied thermo-mechanical loading conditions, and post-mortem analyses.
The candidate will work closely with industrial partners and software developers, gaining experience both in fundamental research and practical application development.
The project is part of the Swedish competence centre BASE and contributes to its objectives of excellence in battery research and strengthening academia–industry collaboration.
Supervision: Professor Artem Kulachenko (main supervisor) and co-supervisors from KTH and RISE are proposed to supervise the doctoral student. Decisions are made on admission.
A postgraduate education at an institution that is active and supportive in matters pertaining to working conditions, gender equality and diversity as well as study environment.
Possibilities to contribute to highly industrially relevant research.
Opportunities to develop advanced computational and experimental skills.
Admission requirements
To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:
passed a second cycle degree (for example a master's degree), or
completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
acquired, in some other way within or outside the country, substantially equivalent knowledge
In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:
independently pursue his or her work
collaborate with others,
have a professional approach and
analyze and work with complex issues.
Additional qualifications that are advantageous (but not mandatory):
proficiency in numerical methods such as finite element analysis
experience with programming languages (e.g., Python, Matlab, C++, Fortran)
strong background in mechanics of materials or computational modelling
interest in interdisciplinary collaboration
potential for developing skills in teaching and laboratory work
prior experience in battery research, electrochemistry or multiscale modelling is an asset
After the qualification requirements, great emphasis will be placed on personal skills.
Target degree: doctoral degree
Information regarding admission and employment
Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
Apply for the position and admission through KTH's recruitment system. It is the applicant’s responsibility to ensure that the application is complete in accordance with the instructions in the advertisement.
Applications must be received at the last closing date at midnight, CET/CEST (Central European Time/Central European Summer Time).
Applications must include the following elements:
CV including your relevant professional experience and knowledge.
Application letter with a brief description of why you want to pursue research studies, about what your academic interests are and how they relate to your previous studies and future goals. (Maximum 2 pages long)
Copies of diplomas and grades from previous university studies and certificates of fulfilled language requirements (see above). Translations into English or Swedish if the original document is not issued in one of these languages.Copies of originals must be certified.
Representative publications or technical reports. For longer documents, please provide a summary (abstract) and a web link to the full text.
Other information
Striving towards gender equality, diversity and equal conditions is both a question of quality for KTH and a given part of our values.
It may be the case that a position at KTH is classified as a security-sensitive role in accordance with the Protective Security Act (2018:585). If this applies to the specific position, a security clearance will be conducted for the applicant in accordance with the same law with the applicant's consent. In such cases, a prerequisite for employment is that the applicant is approved following the security clearance.
We firmly decline all contact with staffing and recruitment agencies and job ad salespersons.
