Conclusion and Outlook

Abstract

This book presents results on the chemical and electronic structure of intercalation cathode and solid-electrolyte interfaces in Li-ion batteries on the sub-nm scale and discusses the fundamental formation mechanisms for interfaces between ionic materials on the basis of energy level concepts. The results are obtained by a surface science approach on model surfaces and interfaces using thin film technology and photoemission as main preparation and analysis techniques. Model systems covered by this book are LiCoO₂ layered oxide thin film surfaces, carbonate solvents and carbonate solvent based LiPF₆ liquid electrolytes, respectively, as well as phosphate-based LiPON amorphous solid electrolyte films.
