Lithium–Molybdenum–Borate Glasses Doped with Cu 2+ ions as Solid Electrolytes

Glasses are synthesized with a particular composition (in mol%) of 40Li 2 O–(4 − x)MoO 3 –56B 2 O 3 : xCuO by melt quenching process. Dielectric properties like dielectric constant (ε') and loss tangent (tanδ) are measured at different frequencies 10 2 –10 5 Hz in temperature range 30 °C–280 °C by using LCR meter (HP model 4263B). The studied glass material with x = 0.6 mol% has exhibited the highest values for AC conductivity ( σ ac ), molar polarizability ( α m ) and nonlinear optical susceptibility ( χ (3) ). These glass materials can act as electrolytes in lithium-ion batteries and as optical elements in photonics applications.
