      abstract     = {Coming from the global picture of climate change and the
                      crucial need to reduce greenhouse gases there is a huge
                      demand for renewable energies. Innovations in different
                      fields are necessary to account for the increased demand in
                      generation, storage and distribution that evokes.The storage
                      of green electricity is one example with the challenge that
                      every application has different requirements in cost,
                      lifetime, gravimetric and volumetric energy density. In the
                      sector of individual mobility, a user will expect a
                      comparable cost, safety and driving range of an electric car
                      as the one that can be obtained from a combustion engine.
                      Therefore, the future generations of battery systems in
                      electric vehicles (EV) need to become cheaper and at the
                      same time gain energy density.Ni-rich NCM-type layered oxide
                      materials are promising candidates to satisfy those needs.
                      The main advantages of increasing the Ni content lies in an
                      increased energy density at the material level and the
                      reduction of cobalt as critical raw material.There are
                      however mayor drawbacks in terms of instability issues and
                      cycling stability. Several mitigation strategies are often
                      applied in literature such as doping to mitigate strong
                      lattice parameter variations, coatings to protect the
                      surface in contact with the electrolyte or core
                      shell/gradient concentration design approaches. Although it
                      is well-known that each of these approaches separately
                      benefits the cycling stability of Ni-rich cathode materials,
                      there are however no systematic reports investigating the
                      simultaneous combination of two of the approaches.However a
                      combination of coating and doping will be needed to overcome
                      the instability issues for NCM materials with Ni contents
                      above 90 $\%.In$ this work, the combination of Zr as
                      frequently used dopant in commercial materials with
                      W-coatingsis thoroughly investigated with a special focus on
                      the impact of different processing conditions and
                      post-processing temperatures. Beside material
                      characterization via XRD, SEM, TEM and XPS also the
                      electrochemical performance in Lithium ion batteries (LIBs)
                      is reported. It sheds light onto the importance to not only
                      investigate the effect of individual dopants or coatings but
                      also the interactions between both.},
