As a PhD student you will collaborate with experts in computational mechanics, materials science, physics and chemistry. Your responsibility will be to develop computational models within Chalmers' multi-physics computational framework. You will also make structural battery composites and characterise their multifunctional performance using test methods that we develop at Chalmers.
Project description
Your project will be part of the activities on Structural battery composites at Chalmers. Chalmers has pioneered this research for more than one decade. The research is performed in an interdisciplinary team across Chalmers and at our partner universities KTH the Royal Institute of Technology and Imperial College London. Currently, the teams at the three universities comprise approximately 40 people. The project is funded by The Swedish Research Council (VR).The PhD position is for five years, with research training spanning over four years, and an additional year involves teaching.
Batteries in electric vehicles constitute a large part of their weight, without providing any load-bearing functionality. A structural battery, on the other hand, is one that works as both a power source and as construction material in for example the car body, aircraft interior, etc. This is coined as "massless" energy storage, because in essence the battery's weight vanishes when it becomes part of the load-bearing structure.
For structural batteries to be useful they must perform their electrical energy storage and supply functions under severe mechanical loads, and vice versa their mechanical integrity must be maintained for all states of charge. Here, we set out to develop fully coupled electro-chemo-thermomechanical models for analysis and design of structural battery composites, as well as electrochemical-mechanical tests for model validation and data generation. The main purpose of the project is to advance the predictive capabilities related to coated electrode material in such structural batteries. Thereby, we aim to establish a reliable tool for guiding the development of all-fiber structural batteries. More specifically, the following project aims will be targeted: (i) Development of an accurate and efficient numerical framework for computational upscaling of thin electro-chemo-mechanical interphases; and (ii) Establishment of a full cell electro-chemo-mechanical model of the proposed all-fiber structural battery.
The model development will be guided by both experimental data and theoretical principles from composite materials mechanics and electro-chemistry. A computational framework developed within Chalmers' structural battery team will be extended and used to guide further materials development. Material testing and characterisation will be performed in our Composites Laboratory at the Department.
Information about the division and the department
The PhD student position will be placed at the Division of Material and Computational Mechanics (Department Industrial and Materials Science). The work will be carried out in collaboration with researchers at the Division of Materials and Manufacture and the Department of Physics at Chalmers as well as colleagues at KTH the Royal Institute of Technology, Stockholm, Sweden, Imperial College London, UK, and TU Braunschweig, Germany.

https://www.youtube.com/watch?v=IB81lkPGGlE. Major responsibilities
Your major responsibility as a PhD student is to pursue your own doctoral studies related to the project. The major goal of the project is to develop models for coupled eletro-chemo-thermomechancial processes in structural batteries and their interphases and their experimental characterisation. This includes the development of multi-physics material models, implementations in a finite element code, and experimental characterisation. The modelling/experimental scope can be adjusted based on the candidate's own interests. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. Your research activities will contribute to enhanced knowledge in the scientific field, in particular by presenting your results in scientific journals and at international conferences.
In addition to the research project, you will also take courses on the advanced level within the Graduate school of Solid and Structural Mechanics. The position also includes teaching courses within Chalmers' undergraduate level, or performing other duties at the department, corresponding to up to 20 percent of working hours.
Qualifications
We expect you to have a MSc in Applied Mechanics, Solid Mechanics, Materials Science or Engineering, Mechanical Engineering, Physics, Chemistry / Chemical Engineering or similar. Knowledge in FEM (including programming thereof) is required. To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field.
Education in materials science, experimental techniques, numerical analysis and programming is meritorious.
Since communication of knowledge results towards academic and industrial partners is a central part of the work, communicative skills in English (oral as well as in writing) are vital. Furthermore, it will also be expected that you can take on responsibilities within the project, have the ability to take own initiatives and, when needed, work independently. At the same time, being a successful researcher also involves working with others as well as disseminating the results within existing and new networks, both within academia but also to industry and society. Therefore, networking skills, team work skills and quality assurance are important.
Knowledge of the Swedish language is desirable but not a requirement. Chalmers offers Swedish courses.
Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
