Mercury Thiogermanate Glasses HgS-GeS2: Vibrational, Macroscopic, and Electric Properties

“…In lead and mercury thiogermanates, the observed non-monotonic conductivity trends might be related to structural changes of the glassy host, GeS 2 and Ge 2 S 3 . Similar non-monotonic behavior was also observed for semiconducting thallium thiogermanate glasses . The structural changes in the glassy host and their effect on electronic transport need to be checked using advanced structural studies and ab initio modeling.…”

Alkali Halide‐Doped Ga2S3–GeS2 Glasses

“…Previous reports for the (MCl) x (Ga 2 S 3 ) 0.2–0.2 x (GeS 2 ) 0.8–0.8 x systems (M = Li, [ 10 ] Na, [ 17 ] and Cs [ 13 ] ) have shown similar trends: a decreasing T g evolution with increasing MCl content without a clear effect of the cation nature. This behavior is different from that for (M 2 S) x (GeS 2 ) 100– x system (M = Ag, Li, Na; [ 23 ] K, Rb, Cs; [ 24 ] and Tl [ 25 ] ) where the T g ( x ) diverges at higher mobile ion content. The structural investigations could explain the observed difference and will be discussed elsewhere.…”

Ionic Conductivity and Structure of Glasses Synthesized by Mechanical-Milling Methods in the x[Na2S]–(100 – x) [0.5GeS2–0.5Ga2S3] System

“…3,4 As solid-state electrolytes, chalcogenide glasses are considered a promising solution for nextgeneration batteries due to their simple structure and enhanced safety. 5,6 Although most current studies on solid-state batteries are based on lithium, because of the high specific capacity of lithium, problems with lithium dendrite growth and the polysulfide shuttle effect make sodium-ion batteries stand out as a dark horse. 7−9 As the Na atom is heavier and larger than the Li atom, the gravimetric and volumetric energy densities of Na-ion batteries are not expected to exceed those of Li analogues.…”

“…Sulfide-based glasses and glass ceramics are well acknowledged for their high ionic conductivities compared to their oxide counterparts. , Furthermore, their machinability and wide compositional flexibility provide advantages to optimize the conductivity properties. , As solid-state electrolytes, chalcogenide glasses are considered a promising solution for next-generation batteries due to their simple structure and enhanced safety. , Although most current studies on solid-state batteries are based on lithium, because of the high specific capacity of lithium, problems with lithium dendrite growth and the polysulfide shuttle effect make sodium-ion batteries stand out as a dark horse. − As the Na atom is heavier and larger than the Li atom, the gravimetric and volumetric energy densities of Na-ion batteries are not expected to exceed those of Li analogues . However, this would not be considered a critical issue in large-scale industrial production, where the battery cost and durability are the most important considerations. , …”
