Project description:

This project aims to develop new nanomaterials for application in Li-ion batteries. The research is focused on synthesis methods that are industrially relevant and are based on the solvothermal reaction of the materials being studied. The main focus is on synthesis in supercritical fluids which has great potential as a new, environmentally friendly way to produce chemicals industrially.

 

After the synthesis, the nanoparticles are structurally characterised with the help of X-ray diffraction, neutron diffraction, TEM/SEM, SAXS, XRF, ICP, BET and potentially X-ray absorption techniques (XANES/EXAFS). Our group has developed and implemented with great success a novel way for in-situ measurement of solvothermal reactions. Therefore, the research will focus especially on in-situ synchrotron X-ray diffraction measurement to study reaction mechanism and nanoparticle growth. The electrochemical characteristics of these materials will also be studied using the newly developed battery-lab in the Department of Chemistry at Aarhus University.
