Magnesium Substitution in Ni‐Rich NMC Layered Cathodes for High‐Energy Lithium Ion Batteries (Adv. Energy Mater. 8/2022)

Li-Ion Batteries In article number 2103045, Aurora Gomez-Martin, Richard Schmuch, and co-workers report the effect of Mg substitution on mitigating the structural challenges of Ni-rich layered oxide cathode materials upon cycling in lithium-ion batteries. While partial substitution of Mg in Li sites linearly reduces the initial capacities at a given upper cut-off cell voltage, the attainable cycle life is significantly extended.
