abstract = {Ni-rich LiNi1−x−yMnxCoyO2 (NMC) layered oxides are
promising cathode materials for high-energy density lithium
ion batteries but suffer from severe capacity fading upon
cycling. Elemental substitution (= doping) with Mg has
repeatedly attracted attention in NMC materials to overcome
instability problems at reasonable cost, yet rational
compositional tuning is needed to guarantee sufficient cycle
life without compromising energy density on the material
level. Herein, a series of Mg-substituted NMC materials with
90 $mol\%$ Ni are investigated regarding key performance
metrics in NMC || graphite full-cells benchmarked against
LiNi0.80Mn0.10Co0.10O2 and LiNi0.90Mn0.05Co0.05O2
synthetized using the same co-precipitation route. A linear
correlation between cycle life and attainable gravimetric
capacities is demonstrated, which are directly influenced by
the degree of Mg substitution and the amount of Li+ cycled
upon (de-)lithiation processes. A Mg content <2 $mol\%$
should be considered to take notable benefit from the
increase in Ni content from 80 to 90 $mol\%$ to achieve a
higher energy density. The present study highlights the
importance of evaluating the true implications of elemental
substitution on cell performance and is expected to be an
insightful guideline for the future development of NMC-type
cathode materials in particular with high Ni and low Co
content.},
