Abstract

This study reports the feasibility of utilizing focused ion beam-scanning electron microscopy sectioning to reconstruct the 3D structure of electrodes before and after extended electrochemical cycling. The observed fragmentation of Li-rich layered spherical particles is speculated to be a possible cause of capacity fading.
