abstract = {Ni-rich layered oxide cathodes are promising candidates to
satisfy the increasing energy demand of lithium-ion
batteries for automotive applications. Thermal and cycling
stability issues originating from increasing Ni contents are
addressed by mitigation strategies such as elemental bulk
substitution (“doping”) and surface coating. Although
both approaches separately benefit the cycling stability,
there are only few reports investigating the combination of
two of such approaches. Herein, the combination of Zr as
common dopant in commercial materials with effective Li2WO4
and WO3 coatings was investigated with special focus on the
impact of different material processing conditions on
structural parameters and electrochemical performance in
nickel-cobalt-manganese (NCM) || graphite cells. Results
indicated that the Zr4+ dopant diffusing to the surface
during annealing improved the electrochemical performance
compared to samples without additional coatings. This work
emphasizes the importance to not only investigate the effect
of individual dopants or coatings but also the influences
between both.},
