“…(Ravaine, 1980;Minami, 1987). In addition, the ion conductivity of amorphous glasses is generally higher than that of the corresponding crystalline ones because of their so-called open structure (Tatsumisago, 2004), as shown in Figure 12.…”

The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-LISICON Li 10 SnP 2 S 12 , garnet Li 7 La 3 Zr 2 O 12 , perovskite Li 3x La (2/3) x TiO 3 , NASICON Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , and glass-ceramic xLi 2 S·(1 − x )P − 2 S 5 and their progress are described in great detail. Meanwhile, the review discusses different ongoing strategies on enhancing conductivity, optimizing electrolyte/electrode interface, and improving cell performance.

“…Their ionic conductivity (r) is several orders higher than those of their oxide analogs. This is generally true for glasses in which O is replaced by S [1], the higher polarizability of the S atom being the reason for higher r. Binary lithium phosphate and thiophosphate glasses as well as ternary glasses doped with lithium halides [2][3][4] are of particular interest as lithium based glasses offer more r compared to other anion based glasses. Kennedy et al have carried out elaborate studies on the preparation, characterization and transport properties of binary glass systems Li 2 S-P 2 S 5 , Li 2 S-SiS 2 as well as quarternary systems Li 2 S-P 2 S 5 -SiS 2 -LiI [2][3][4].…”

“…Glassy solid electrolytes have distinct advantages over their crystalline counterparts viz. isotropic properties, absence of grain boundaries, ease of thin film formation, flexibility of size and shape at satisfactory cost [1]. In addition, glasses can be prepared over a wide range of composition which gives better control over properties.…”

Abstract. The electrical conductivity results of lithium borosilicate glasses with addition of Li2SO4 and LiC1 have been critically analyzed. In general, it is observed that the factors viz. lithium fraction, fL~ and the number of non-bridging oxygens (NBOs) govern the ionic conductivity in the lithium conducting glasses. For the same fLi, the presence of mixed formers in the glass gives higher conductivity compared to that of the glass with only one former. Thus the competitive network of glass in mixed former systems provides higher mobilities for lithium ions and hence high ionic conductivity. The addition of Li2SO 4 and LiC1 in the lithium borosilicate glasses gave enhancement in the conductivity. However, the mechanism of enhancement in conductivity is different in the two glass systems. The comparison of the result of binary, ternary and quaternary glass systems suggests that in general, the decrease in activation energy, increase in fLi and increase in NBOs gives rise to enhancement in conductivity. For the same value of fLJ the higher conductivity is exhibited by glasses with lower value of K ( K = SiO2 / B203).
