Influence of an ionic liquid on the conduction characteristics of lithium niobophosphate glass.

A new solid electrolyte, mol% 1 [EMI]BF4-99(0.5Li2O-0.45P2O5-0.05Nb2O5), with room temperature ionic conductivity of 1.7 × 10-5 S/cm is reported for solid state device applications. Glass transition temperature of the hybrid system decreases by 20 K as compared to the pristine glass. Raman spectra in conjunction with thermal studies reveal that the addition of ionic liquid to the glass seems to increase the disorder in the glass leading to enhanced conductivity.
