Abstract

Lithium-Ion Batteries In article number 2406615 Philipp Schweigart, Ann Mari Svensson, Maria Valeria Blanco, and co-workers employ operando X-ray diffraction to unveil the complex lithiation and delithiation dynamics of silicon-graphite anodes with high silicon content. It investigates the competing processes of graphite lithiation, silicon amorphization, and Li15Si4 formation. Understanding the critical impact of electrode composition, lower cutoff potential, and applied current is key to optimizing operating conditions for advanced silicon-graphite anodes in lithium-ion batteries.
