520 _ _ |a 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 the Federal Ministry of Education and Research of Germany through project 03EK3572 (UNIBAT), from the Federal Ministry of Economic Affairs and Climate Action of Germany through project no. 03ETE016F (Optikeralyt) and the Helmholtz Association of German Research Centers for their financial support within the Helmholtz program “MTET: Materials and Technologies for the Energy Transition,” topic “Electrochemical energy storage”.
