Jakob Bæk Grinderslev

During his PhD studies, Jakob Bæk Grinderslev researched in new energy materials. Renewable energy such as solar and wind fluctuates over time, and energy storage represents the main obstacle in a transition towards a society based on these energy sources. Jakob Bæk Grinderslev has synthesized and studied these new materials for hydrogen storage and batteries.

The new research findings have resulted in a large array of novel energy materials based on complex hydrides with boron and nitrogen. Consequently, these materials contain dihydrogen interactions in the solid state, which influences the chemical and physical properties. This can result in hydrogen release at low temperatures, but also influence the dynamics in the structures and result in high cation mobility in the solid state. Thereby, complex hydrides has the potential as solid-state electrolytes for next-generation batteries, not only for lithium, but also for new types of batteries based on magnesium and calcium.

The PhD study was completed at the Department of Chemistry and the Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
