“…Both silver and lithium glasses show similar behavior on the conductivity. The ionic conductivity increases by three orders of magnitudes when adding dopant salt, AgI or LiI on the base glass AgPO 3 or LiPO 3 . But, their ionic conductivity is lower for lithium phosphate glasses than the silver glass.…”

Recently, there has been increasing demand on finding new solid electrolytes based on glassy material, due to their potential applications for solid state rechargeable battery. Superionic conducting glasses have many advantageous compared with the crystalline, or composite electrolytes, such as easy in preparation, low melting point, no grain broundary, wide composition range and easy to be formed as thin film. Among superionic glasses, the family of silver phosphate glasses (AgI) x (AgPO 3 ) 1-x and lithium phosphate glasses (LiI) x (LiPO 3 ) 1-x , are the most interested materials to be investigated. Many experiments have been performed to investigate the properties of those materials. This paper will review the recent results of the lithium glasses (LiI) x (LiPO 3 ) 1-x , such as the preparation, appearance, structure, electrical and thermal properties. The x-ray data shows the precipitate occured at x=0.4, indicating the solubility limit of (LiI) x (LiPO 3 ) 1-x was reached at this composition. The microstructure data observed by SEM showed the different area between the smooth surface for x=0.3 and appearance of cluster at x=0.4. Comparison between glassy LiPO 3 and (LiI) 0.3 (LiPO 3 ) 1-x as the result of Raman spectra analysis, suggested a new feature at around 1000 cm -1 , indicating the depolymerization of the non bridging oxygen, due to the presence of LiI component. The room temperature conductivities of (LiI) x (LiPO 3 ) 1-x with x=0.3 and 0.4 are 2.7x10 -6 and 8.8x10 -7 S/cm, respectively, which are 3 orders of magnitudes higher than the undoped glass LiPO 3 . In general, the silver glass has better ionic conductivity than the lithium glass; but in application the lithium battery has better performance and produces higher voltage.

“…Above all, a lot of examinations have been performed on the silver iodide -silver phosphate series, (AgI) x (AgPO 3 ) 1-x , because of some advantages. For example, the low glass transition temperature varies from 450K to 350K as x increases [3,4]. The ionic conductivity at room temperature is about 10 -2 S cm -1 , which is comparable to that of liquid electrolytes [3,5].…”

Neutron scattering experiment and Reverse Monte-Carlo (RMC) analysis have revealed that the large structure change has occurred around the glass transition temperature to form the tetrahedral structure PO 4 on the glass state [6][7][8][9][10].…”

Abstract. Molecular dynamics (MD) simulation on molten and glass state of AgI-AgPO 3 have been performed to investigate the structural features and transport properties. In MD, the screened Born-Mayer type potentials including the effect of polarizability of ions have been used. The structure, conductivity, shear viscosity, and Voronoi polyhedron are discussed in relation with the temperature change.

“…Its room temperature conductivity is one of the largest known ͑ Ϸ 10 −2 S/cm at 25°C͒, 3,4 its fabrication is easy, and, as it turned out, it can readily be shaped into a sharp tip, as shown in Figs. 1͑b͒-1͑d͒. All tested tip geometries provide sufficiently high electric fields at the apex to allow ion emission into vacuum.…”

A bright ion source based on the solid electrolyte (AgI)0.5(AgPO3)0.5 has been developed. The solid electrolyte source provides stable currents of Ag+ in the microampere regime that make it suitable for focused ion beam applications. Similar conditions are expected for different solid electrolyte materials and their corresponding ions. This opens a broad field of applications in structuring and modifying devices on a nanometer scale using focused ion beams.
