Investigation on the Dynamic Oxidation States of Fe in Novel Sustainable Cathodes: LiNi0.8Fe0.1Mn0.1O2 for Lithium Ion Battery

A newly developed and more environmentally friendly cathode material (LiNi0.8Fe0.1Mn0.1O2, NFM811) has been successfully synthesized. The proposed experiment is dedicated to elucidating the dynamic alterations in the oxidation state of the Fe element during the cycling process, utilizing synchrotron Mössbauer Spectroscopy. We aspire to deepen our understanding of the charge compensation mechanism within this material.
