Postdoc position in High Entropy Alloys for Battery Application

The Department of Chemistry - Ångström conducts research and education in the chemistry field. The department has 270 employees and a turnover of 300 million SEK. At the department's six programmes, we conduct very successful research of high international standard. We have a large number of externally funded research projects, often with international collaborations, and we see continued good growth in our subject area. The department has education assignments in engineering programmes and master's programmes. More information is available on our website.

Work duties

The project focuses on designing and creating new high-entropy alloys for use as electrodes in both lithium-ion and sodium-ion batteries. The goal is to increase storage capacity, both per weight and volume, as well as to counteract the pulverization that commonly occurs due to volume changes associated with charging and discharging of the active material through an intrinsic buffer effect. 

The overall aim is to design new materials and optimize fundamental battery performance, as well as to achieve increased mechanistic understanding. The methods primarily involve synthesis, material characterization, and construction and testing of electrochemical cells.

The postdoctoral researcher will be part of Prof. Patrik Johansson's new research group at Uppsala University, which is part of the research environment Ångström Advanced Battery Centre (ÅABC). This applied and innovation-focused research project is mainly funded by the Swedish Research Council within the framework of a Distinguished Professor Grant for "Next Generation Batteries". The project is strongly connected to activities at Luleå University of Technology and Chalmers University of Technology.

The main duties are to conduct research. They may also include teaching, up to 20% of working time, as well as supervision of and collaboration with doctoral students and master's thesis students.

Requirements

A doctoral degree in chemistry or materials science, or an international degree deemed equivalent. The degree must be completed no later than the time of the employment decision.

Normally, the degree should have been awarded within the past three years, calculated from the application deadline. In special circumstances, the degree may have been awarded earlier. Special circumstances refer to leave due to illness, parental leave, elected positions in trade union organizations, and similar situations.

Applications are primarily assessed based on the applicant's ability to conduct independent research and their scientific excellence. The quality of each individual scientific work carries more weight than the number of publications.

Consideration is also given to strong collaborative skills, motivation and independence, as well as how the applicant's experience and expertise complement and strengthen ongoing research at the department and how they can contribute to its future development. The candidate must have excellent written and oral English skills and experience in synthesis and analysis of high-entropy alloys.

Desirable qualifications

Experience in X-ray diffraction methods, battery material development and testing are an asset.

About the employment

The employment is a temporary position of 2 years, and potential 1 year extension, according to central collective agreement. Scope of employment 100%. Starting date as agreed. Placement: Uppsala.
