Silver sulfide based glasses (I). Glass forming regions, structure and ionic conduction of glasses in GeS2Ag2S and GeS2Ag2SAgI systems

Abstract: Ag2S forms with GeS2 stable glasses over a wide range of compositions (0–55% Ag2S mol%) In the same system, more complex glasses obtained by dissolving silver iodide have been synthesized with up to 50 mol% AgI Raman spectra are presented and a vibrational assignment in terms of bridging and non-bridging sulfur has been made The electrical conductivity of these glasses has been measured over a temperature range (−50°C− + 50°C) and for various compositions by the complex impedance diagram method At 25°C, the conductivity reached a maximum value of 6 × 10−3 Ω−1 cm−1 Whatever the glass used, the same limit value of conductivity (σ − 10 su−2 Ω −1 cm −1 ) and activation energy ( E σ ⋍ 025 eV ) are obtained for the highest content of silver iodide A conduction mechanism is proposed

Synthesis of Li + Ion Conductive PEO-PSt Block Copolymer Electrolyte with Microphase Separation Structure

Abstract: A block copolymer consisting of a polyethylene oxide (PEO) and polystyrene (PSt) was applied to the preparation of a microphase separation of solid polymer electrolyte containing with high ionic conductivity at room temperature (more than ). The polystyrene block provided the mechanical strength and the polyethylene oxide one allowed for fast ion conduction in the polymer electrolyte without any plasticizer. Using this new microphase separation solid polymer electrolyte, a electrolyte/Li metal cell was constructed and tested. The prepared cell exhibited a discharge capacity of at .
