NANOSTRUCTURED IONIC CONDUCTORS: INVESTIGATION OF SiO2-MI (M = Li, Ag) COMPOSITES

Résumé

Synthesis and characterization of porous Vycor (R) 7930-MI (M = Li, Ag) composites are discussed. Two types of composites were prepared: sintered composites obtained by classical sintering (CS) and composites obtained by electro-crystallisation (EC). In the case of Lil composites all increase of the conductivity of two orders of magnitude as compared to the conductivity Of pure Lil was observed. In Such a case good coating of insulating particles and filling of the pores was observed. In the case of Agl the main important finding is the presence of an hysteresis phenomenon in the conductivity versus temperature Curve at a temperature close to the transition alpha <->beta
