Silicon‐Germanium Solid Solutions with Balanced Ionic/Electronic Conductivity for High‐Rate All‐Solid‐State Batteries (Adv. Energy Mater. 40/2025)

All-Solid–State Batteries Constructing a silicon-germanium solid solution enables concurrent modulation of electronic and ionic transport in silicon anodes for all-solid-state batteries. This synergistic regulation markedly enhances fast-charging capability and long-term cycling stability, thereby advancing the feasibility of high-energy-density and durable all-solid-state batteries for electric vehicles, electric aircraft, and other emerging technologies.
