      abstract     = {One of the most essential properties of lithium batteries
                      in application is their high energy density, implying high
                      lithium ion storage capabilities in the electrodes.
                      Today’s conventional carbon-based anodes still leave
                      considerable room for improvement. Pure elementary lithium
                      metal, sometimes described as the “Holy Grail” of all
                      lithium anode materials, suffers from huge volume changes
                      during charge/ discharge, and their predisposition to
                      short-circuiting the battery cells during charging by the
                      creation of metallic lithium filaments which completely
                      perfoliate the electrolyte. Silicon is regarded as one of
                      the most promising anode materials in advanced lithium
                      batteries due to its high lithium ion storage capacity,
                      however, also silicon exhibits extensive volume changes
                      during electrochemical cycling. Mixtures of silicon with
                      other elements potentially forming transition metal
                      silicides are under intense investigation as mechanically
                      stable and electronically conductive frameworks, with
                      additional electrochemically active silicon in between. In
                      this work it is shown how deployments derived from
                      high-throughput experimentation allow a deeper insight into
                      the interplay between phase formation, electrochemical
                      performance and proportion of active and inactive material
                      in a battery cell. A holistic approach for the development
                      of material libraries based on materials phase diagrams is
                      presented, allowing a significantly deeper insight into the
                      interaction of ceramic processing technologies,
                      microstructures, crystal phases, and their impact on the
                      electrochemical properties. This work has been supported by
