Silver-ion-sconducting solid electrolytes with low activation energy are important because of their distinctive application potential in solid-state batteries operated within a broad temperature range, especially below room temperature. Achieving glassy solid electrolytes with high ionic conductivity, low activation energy, and good thermal stability is a continuous challenge for the design and synthesis of novel fast ion-conducting glasses. Here, we report markedly low activation energy and high room-temperature ionic conductivity in melt-quenched GeS2–Sb2S3–AgI chalcogenide glasses. Homogeneous 2.5GeS2–27.5Sb2S3–70AgI glass presenting high glass transition temperature of 135 °C shows high ionic conductivity of 9.18 × 10–3 S/cm at 25 °C and low activation energy of 0.07 eV, which is the lowest among those of Ag-ion glassy electrolytes. Structural characterization by using Raman spectra suggests that, in the disordered network structure of GeS2–Sb2S3–AgI glasses, the formation of chain fragments composed by [SbS3–x I x ] n , which is similar to the double chain of [(SbSI)∞]2 in the SbSI crystal structure, provides possible diffusion pathways to facilitate low-barrier concerted migration of silver ions.

“…However, the rapid decomposition of the material in the presence of moisture makes its use as a substrate material impractical. Several silver oxyacid based compounds of the form AgI x (Ag y MO z ) 1− x where M = P, As, Se, Te, Cr, Mo, and W have been found to be ionic conductors and are significantly less reactive to moisture compared to RbAg 4 I 5 . In particular, the structure and tunability of the glass transition, activation energy, and ionic conductivity of (AgI) x (AgPO 3 ) 1− x glass mixtures have been well studied due to the wide transparent glass forming region from x = 0 to 0.6 .…”

Surfaces with silver nanostructures are useful, due to their potential to resonate strongly with visible light. This report demonstrates a process for the directed extraction of silver at the surface of a transparent superionic conductor. A focused electron beam incident on superionic AgIAgPO3 glass results in localized negative charge deposition, which is neutralized by the electrochemical reduction of free silver ions. This process was characterized for beam energies ranging from 1 to 12 kV and primary beam fluence ranging from 50 pC μm−2 to 35 nC μm−2. For electron fluence less than 2.5 nC μm−2 the process produces vibrant coloration of the glass which can be tuned throughout the entire visible spectrum. Fluence greater than 2.5 nC μm−2 results in the controlled writing of bulk silver on the surface, with a minimum line width as small as 400 nm and narrow gaps as small as 50 nm. The high ionic conductivity of the substrate is shown to be a vital component to the process, allowing the wide range of colors to be produced along with the controlled, nondendritic growth of silver structures.
