Influence of germanium oxide addition on the electrical properties of Li2O-B2O3-P2O5 glasses

Popis výsledku v původním jazyce

Lithium ion transport upon the addition of germanium oxide in a series of mixed glass former lithium borophosphate glasses has been investigated. The electrical and dielectric properties of (100 - x)[0.5Li(2)O-0.1B(2)O(3)-0.4P(2)O(5)]-xGeO(2) with 0-25 mol% GeO2 glasses have been studied over a wide temperature (183-523 K) and frequency range (0.01 Hz-1 MHz). The increase in dc conductivity with the addition of GeO2 is attributed to the formation of ion conducting channels arising from the structural modification and formation of the P-O-Ge linkages, resulting in an easy migration of Li+ ions along these bonds. At higher GeO2 content glass network becomes more densely packed and ionic conductivity is slightly hindered as a consequence of the increase of bonding forces inside the network. Such a decrease in the conductivity is more reflection of the stronger cross-linkage in the glass network than that of the slight decrease in the Li+ ion concentration. The electrical modulus formalism
