Characteristics of solid-state batteries with zinc/cadmium halide-doped silver phosphate glasses as electrolytes

Ion transport studies in zinc/cadmium halide doped silver phosphate glasses

“…quenching technique was employed for preparing both undoped and doped silver phosphate glasses as reported earlier [19,24]. In the case of undoped silver polyphosphate glass, a mixture of AgNO3 and NH4H2PO 4 in 1:1 molar ratio was heated in a platinum dish in a muffle furnace for 4 hours at a fixed temperature (700 -800 ~ The melts were then quenched over ice cooled stainless steel plates to obtain glassy samples.…”

“…Amongst these superionic glasses, Ag + ion conducting phosphate glasses have attracted special attention mainly due to the ease of their preparation in different forms at a lower temperature, environmental stability, interesting simple structure, high ionic conductivities and as promising glassy electrolytes for the development of solid state batteries and other electrochemical devices [9,[15][16][17][18][19]. Addition of silver halide to silver phosphate glasses enhances their conductivities and decreases their glass transition temperatures T~, without significantly altering the phosphate network [20][21].…”

Luminescence properties of Dy3+ doped zinc–aluminum–sodium–phosphate (ZANP) glasses for white light applications

“…However they have poor chemical durability and can be improved by adding small amounts of one or more oxides such as ZnO, PbO, Al 2 O 3 and Fe 2 O 3 to them [12]. Addition of suitable fluorides to the phosphate glasses can decrease the phonon energy, which reduces non-radiative decay and enhances radiative emission rates of RE 3+ ion energy levels, leading to much higher quantum efficiencies [13].…”

Investigation on the Spin Hamiltonian Parameters and the Local Structures for Cu2+ Centers in Sodium Phosphate and Heavy Metal Fluoride Glasses

“…Sodium phosphate and heavy metal fluoride glasses usually exhibit unique properties such as high thermal expansion coefficient [1,2], low glass transition temperature [3], and fluorescence characteristics [4] and may act as solid state electrolytes in batteries [5] as well as solid state lasers [1]. Especially, these glasses doped with transition-metal ions show unique optical and electrical [6 -8], photoacoustic [9], and ion conductivity [10].…”
