Novel amorphous electrode materials for Li- and Na-ion batteries

Traditional intercalation type electrodes are highly crystalline materials in which the ions are intercalated between atomic layers or channels in the atomic lattice. However, several amorphous (or highly disordered) materials have been shown to exhibit excellent properties as battery electrodes. This class of materials is highly unexplored in spite the fact that amorphous materials may significantly reduce the production costs of the electrodes.

The goals of this project to gain a better fundamental understanding of nature of ion storage in amorphous materials. We aim to answer how the structure of the amorphous material affects the capability to efficiently store ions and how the structure changes during dynamic charge-discharge cycling.

This project is funded by a Distinguished Lecturer Grant from the Carlsberg Foundation.
