Abstract
All-solid-state lithium batteries hold great potential to enable next-generation energy storage devices. The electrochemical performance of such solid-state batteries is strongly dependent on the physiochemical interactions underlying the porous cathode microstructure. The spatial arrangement and composition of constituent phases in the cathode determines effective ionic transport properties, electronic conductivity and electrochemically active area. In this work, we connect the interplay between the coupled kinetic and transport processes in the cathode to the distinct internal resistance signatures. The mesoscale underpinnings of the porous cathode are elucidated in the context of electrochemical performance at operational extremes.
