Lithium Transport Mechanisms
Lithium Transport Mechanisms in Carbon Anodes for Lithium-Ion-Batteries
This project aims to further research the lithium transport mechanisms inside of graphitic electrodes. This detailed understanding of the transport processes is important to better understand the degradation of batteries. The activities will be actively supported by modelling activities to predict the batteries behavior.
The scope of this project is to develop the methods needed to research different states of charge in graphites with an optical cell and NMR. A model is to be developed which represents the transport processes of the lithium.
The lithium transport mechanism will be investigated using the combination of two methods. High states of charge are being investigated by the color changes caused by the lithium insertion into the graphite. Low states of charge do not show this color change and are thus being monitored with nuclear magnetic resonance (NMR). These two different techniques can be combined due to the collaboration of the Forschungszentrum Jülich and the RWTH Aachen University.
