Chemical, Structural, and Electronic Aspects of Formation and Degradation Behavior on Different Length Scales of Ni‐Rich NCM and Li‐Rich HE‐NCM Cathode Materials in Li‐Ion Batteries
Lea de Biasi,Björn Schwarz,Torsten Brezesinski,Pascal Hartmann,Pascal Hartmann,Jürgen Janek,Jürgen Janek,Helmut Ehrenberg +7 more
TL;DR: The characteristic process of formation and mechanisms of fatigue are fundamentally characterized and the effect of chemical composition on cell chemistry, electrochemistry, and cycling stability is addressed on different length scales by use of state-of-the-art analytical techniques, ranging from "standard" characterization tools to combinations of advanced in situ and operando methods.
