Abstract The utilization of silicon anodes in all‐solid‐state lithium batteries provides good prospects for facilitating high energy density. However, the compatibility sulfide solid‐state electrolytes (SEs) with Si and carbon is often questioned due to potential decomposition. Herein, operando X‐ray absorption near‐edge structure (XANES) spectroscopy, ex situ scanning electron microscopy (SEM), nanotomography (XnT) are utilized investigate chemistry evolution nano‐Si composite anodes. Results from XANES demonstrate a partial decomposition SEs during first lithiation stage, which intensified by presence carbon. Nevertheless, performances three cycles Si–SE–C stable, proves that generated media ionically conductive. XnT SEM results show addition improves structural stability anode, fewer pores voids. A chemo‐elasto‐plastic model reveals buffer volume expansion Si, thus enhancing mechanical stability. balance between pros cons reaction kinetics enables anode highest higher specific capacities better rate than pure only SEs.
