Understanding the Doping Modification of High-Ni and Low-Co Oxide Materials by probing the structural and chemical properties using X-ray p

This necessitates the localized probes to comprehensively investigate the structural and chemical evolution of electrodes during battery cycling, revealing how the complex interplay among void formation, interphase growth affects battery properties, such as cycle life and safety. Herein, we propose to combine hard x-ray phase contrast nano-tomography and advanced machine learning approaches to systematically investigate the morphological and chemical behaviours at doped High-Nickel and Low-Cobalt cathodes interphases that are subjected to different cycling protocols. By characterizing the electrode with high spatial resolution and associating with the chemomechanical reactivity and morphological deformation of hundreds to thousands of identified active doped High-Nickel and Low-Cobalt cathodes particles, we aim to develop a theoretical inter- and intra- particle model that could predict the mechanical failure in the high-Ni and low-Co cathode.
