Understanding the effect of Nb substitution on Li-Mn-rich layered oxides

Substitution with 4d/5d-elements has been recently established as promising solution for suppressing capacity and voltage fading in Li-Mn-rich layered oxide cathodes for lithium ion batteries. This study aims at understanding of the underlying working principles of this concept through a systematic...
