Silver iodide is a well-known ionic conductor. However, it shows superionic conductivity only in its high-temperature phase (above∼150 ∘C). It is now demonstrated that various sizes of nanoparticles can be synthesized for which the superionic phase is stable down to ∼30 ∘C. The results suggest promising applications in silver-ion-based electrochemical devices.
