Abstract:The kinetics of composite cathodes for solid-state batteries (SSBs) relies heavily on their micro-structure. Spatial distribution of the different phases, porosity, interface areas, and tortuosity factors are important descriptors that need accurate quantification for models to predict the elec-trochemistry and mechanics of SSBs. In this study, high-resolution focused ion beam-scanning electron microscopy tomography was used to investigate the microstructure of cathodes com-posed of a nickel-rich cathode activ… Show more
