Deskripsi
Here the authors demonstrate a spectroscopic and imaging approach to study redox solid-state phase transformation in lithium ion cathode materials under thermal abuse conditions. The valence curvature of the propagation front alternates as a result of local chemical and structural heterogeneities.
