Steinar Birgisson

During his PhD studies, Steinar Birgisson studied electrode materials for use in lithium and sodium ion batteries. The research mainly focused on the cathode materials: LiMn2O4, MnO2 and NaxMyMn1-yO2 (M = Co, Fe, Ni). Amongst other, Steinar Birgisson conducted real time observations using X-ray scattering. The real time X-ray scattering data provides information about structural changes of these materials during their synthesis of and while they operate in a battery. The research has revealed valuable information about how these materials can be customized to make better batteries.

The PhD degree was completed at the Department of Engineering, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
