This doctoral thesis constitutes a methodology to qualify water-based anode dispersions for the inkjet printing process. The approach was demonstrated with the predominant state-of-the-art anode active material graphite. First, the central product- and process-specific requirements that apply to the dispersions to be processed were aggregated. Subsequently, a suitable dispersant was empirically determined to stabilize the graphite particles in an aqueous solution. In this context, a model was elaborated that allows to describe the dispersion stability. This was followed by a number-based approach to qualify a printable dispersion. Particular attention was paid to the incorporation of the binders and the related effects on the product and the process characteristics.
