Deciphering the Impact of Current, Composition, and Potential on the Lithiation Behavior of Si-Rich Silicon-Graphite Anodes (Small 4/2025)

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.
