New Findings from Al-Azhar University Update Understanding of Non-Crystalline Solids [Study of nanostructure and ionic conductivity of Li1.3Nb0.3 V-1.7(PO4)(3) glass ceramics used as cathode material for solid batteries]

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Non-Crystalline Solids are discussed in a new report. According to news reporting originating in Cairo, Egypt, by VerticalNews journalists, research stated, "Glass sample with composition Li1.3Nb0.3V1.7(PO4)(3) was prepared by quenched melt technique. Double heat treatments performed for different time intervals (12, 18, 24 and 30 h) to obtain glass ceramics with different nanoscale grain sizes."

The news reporters obtained a quote from the research from Al-Azhar University, "The glassy nature was confirmed from the glass transition temperature using differential thermal analysis (DTA) for the as quenched sample. In addition, the X-ray diffraction (XRD) patterns confirmed the glass nature for the as quenched sample. After heat treatment (HT) the structure of all samples was characterized by XRD. Ionic conductivity and impedance measurements of the derived glass ceramics were systematically investigated. It is observed that the electrical conductivity is enhanced by 10(3) times for the heat treated glass sample of 24 h, whereas with further increase of HT time up to 30 h, the conductivity started to decrease."

According to the news reporters, the research concluded: "Therefore, the phase observed in the 24 h HT is found more suitable to be used as a cathode material in solid batteries compared to its vitreous counterpart."
