The development of new cathode active materials (CAMs) for lithium-ion batteries (LIBs) critically depends on their durability during battery operation. Therefore, it is the aim of this thesis to identify important degradation mechanisms of layered transition-metal oxide CAMs and to precisely quantify their impact on the electrochemical performance and capacity fading. In order to differentiate between degradation modes occurring at the surface and within the bulk of the materials, we employed on-line electrochemical mass spectrometry (OEMS) as well as X-ray (XPD) and neutron powder diffraction (NPD) in conjunction with several electrochemical and physicochemical analysis techniques.
