Postdoctoral Researcher in Solid-State Batteries: ML-Based Battery State Estimation & Control

Description:

Job Responsibilities The next major breakthrough in battery development is expected to be lithium solid-state batteries (SSB). This concept enables the flammable organic electrolyte in lithium-ion batteries to be replaced with a safer and more compact solid electrolyte. As part of the Swedish government-funded battery initiative COMPEL, which aims to support expertise and excellence in battery research and education for the transportation sector, KTH is launching a coordinated initiative on composite-SSB with seven postdoctoral positions across multiple disciplines, focusing on different aspects along the battery value chain, from synthesis, cell manufacturing, characterization, modeling, to scaled production. The two-year postdoctoral project Machine Learning-Based State Estimation and Control of Electrochemical and Mechanical Processes in Solid-State Batteries will be conducted at the Department of Automatic Control, EECS. The project focuses on developing reduced models for coupled electrochemical and mechanical processes, state estimation methods, and predictive control strategies for solid-state batteries based on data from parallel postdoctoral projects within the initiative. The research aims to increase understanding of how operating conditions, such as charging protocols, temperature, and mechanical stress, affect battery performance, degradation, and lifetime. The work combines physics-based modeling with machine learning for parameter estimation, degradation prediction, and analysis of electrochemical measurement data and structural characterization, including reconstruction and segmentation of X-ray CT data as well as quantitative microstructural analysis. The long-term goal is to enable state-aware battery management and optimized charging strategies. Qualifications Requirements Completed doctoral degree or foreign degree assessed as equivalent to a doctoral degree in automatic control, electrical engineering, engineering physics, applied mathematics, or a related field. This eligibility requirement must be met by the time the employment decision is made. Strong written and oral English proficiency as required for daily work. Strong theoretical background in modeling of dynamic systems, state estimation, control and optimization, as well as good knowledge of machine learning. Awareness of diversity and equal treatment issues with particular focus on gender equality. Meritorious At the application deadline, no more than three years since the doctoral degree or equivalent foreign degree was awarded. Experience with solid-state batteries and modeling, state estimation, or control of electrochemical systems. Demonstrate innovative thinking, creativity, and ability to work independently. Good collaboration skills and ability and interest in working as part of a team. We will place great emphasis on personal qualities. Become Part of KTH KTH shapes the future through education, research, and innovation. As a leading international technical university, we play an active role in driving and contributing to the transition toward a sustainable society. Here you have the opportunity to grow and develop in a creative and dynamic workplace with good working conditions and benefits. Gender equality, diversity, and equal opportunities are a quality issue and a fundamental part of KTH's values as a university and public authority.

Application You apply through KTH's recruitment system. As an applicant, you have primary responsibility for ensuring your application is complete when submitted. The application must contain: CV including relevant professional experience and knowledge. Copy of degree certificate and transcripts from previous university studies. Translations into English or Swedish if the original documents are not issued in a Western European language. Brief statement explaining why you wish to conduct research, your academic interests, and how they relate to your previous studies and future goals. Maximum 1 page long. References or recommendation letters The application must be received by KTH no later than the application deadline at midnight, CET/CEST (Central European Time/Central European Summer Time). About the Employment The employment is permanent, but for a maximum of two years A postdoctoral position is a time-limited merit-based employment with primary focus on research intended as a first career step after completing a doctorate. Other Information For information about the processing of personal data in connection with recruitment. It is possible that an employment at KTH is classified as a security position. If this is the case for this particular position, a security clearance of the applicant will be conducted in accordance with the Security Protection Act (2018:585) with consent. In these cases, approval after security clearance is a prerequisite for employment.
