Originální abstrakt

This work focuses on the analysis of the degradation mechanisms of prismatic Li-ion cells using a correlation between X-ray computed tomography (CT) and scanning electron microscopy (SEM). CT analysis was performed at the beginning of cycling and after cycling to reveal significant changes in structure. SEM analysis was performed on cells disassembled in a fully charged state, which allows observation of the inactive regions of the anode and preparation of a cross-section through the regions with electroplated lithium. Finally, an event diagram describing the rapid aging of the battery is presented and possible solutions are discussed.
