Abstract:
This work investigates the formation and stability of the solid electrolyte interphase on negative electrodes of Li-Ion battery cells and the influence of impurities during and after the formation. It demonstrates, how simplified model experiments can support the progress of understanding complicated commercial-like systems. Furthermore, in this study significant similarities between aqueous and carbonate solvent-based environments are identified. The results serve as a springboard for further fundamental studies and optimization of industrial processes.

Diese Arbeit untersucht die solid electrolyte interphase auf negative Elektroden von Li-Ionen-Batteriezellen und den Einfluss von Verunreinigungen während und nach der Formierung. Sie demonstriert, wie vereinfachte Modellversuche den Verständnis-Fortschritt komplizierter anwendungsnaher Systeme unterstützen können. Die Ergebnisse bieten ein Sprungbrett sowohl für weitere Grundlagenforschung als auch für die Optimierung industrieller Prozesse.
