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.
