Li-S Batterien

In this project, the structure of sulfur-poly(acrylonitrile)-based Li-sulfur batteries is elucidated and correlated with the electrochemical performance of such devices. In particular, the intermediary formation of S8 during cycling and the role of the electrolyte in its reintegration during charging into are investigated. In parallel, issues of the Li-anode such as the prevention of stalactite formation, etc., are addressed. In summary, a comprehensive picture of the chemistry and electrochemistry of Li-sulfur batteries is to be created that ultimately allows for designing high-capacity devices with good cycling stability.
