Highlights from Danish Battery Symposium 2017

The 2017 symposium in the Danish Battery Society was hosted by Dorthe Ravnsbæk and her group at the University of Southern Denmark in a comfortable campus setting outside Odense. The ambition of this years symposium was to follow up on the working groups established last year to enable more networking and direct knowledge sharing. After a short but …

In situ synchrotron XRD on a capillary Li-O2 battery

In situ studies give an opportunity to explore systems with a minimum of external interference. As Li-air batteries hold the promise for a future battery technology the investigation of the discharge and charge components of the cathode and anode is of importance, as these components may hold the key to making a large capacity rechargeable …

In situ study of hydrothermal formation of spinel type LiMn2O4 nanocrystals

Solvothermal reactions have been shown to be a good way to synthesize nanocrystalline materials. Many properties of the product, such as phase composition, crystallite size, morphology and crystallinity, can be controlled by changing and controlling synthesis conditions, such as reaction temperature, heating rate, reaction time, precursor concentration and pH. Ex situ investigation of the effect …

New Spectroscopic Technique developed at Berkeley Lab’s Advanced Light Source

Over the past several years, scientists have developed several ways to study the changes in a working electrode. These include techniques based on hard X-rays, electron microscopy, neutron scattering, and nuclear magnetic resonance imaging. But most of these methods track structural changes. They don’t track electron and ion dynamics directly, which is very important in …

Introduction and TiO2

General introduction to the battery group at Aarhus University and description of how they take advantage of a closely integrated feedback loop between synthesis, structure characterization and electrochemical properties. The battery test cells used in the group is described, including the in-situ split flat cell used to do in-situ XRD tests. Check out the presentation here

In-situ synchrotron powder X-ray diffraction

Our group has developed and successfully used an in-situ measurement setup for the study hydrothermal formation of nanoparticles under sub- and supercritical conditions. The presentation introduces details of the experimental setup as well as explaining each step of the data analysis. As an example of one of our experiment some preliminary results of a temperature …
