Breaking the Upper Limit of Substitution Concentration in Li Argyrodite Solid Electrolytes Using a Single‐Solvent‐Mediated Approach (Adv. Energy Mater. 20/2025)

Solvent‐Mediated Method The upper limit of Si substitution level in the Li argyrodite solid electrolyte is raised using a solvent‐mediated approach. Smaller particles synthesized through this method exhibit a higher surface‐area‐to‐volume ratio, allowing for the incorporation of more Si and Li within larger amounts of interfacial space‐charge layers, compared to the larger particles produced by solid‐state ball milling. More details can be found in article 2500532 by Jin Gu Kang, Dong‐Wan Kim, and co‐workers.
