“…Fu 35 glass−ceramic displayed a bulk conductivity of 1.7 × 10 −3 S cm −1 and a grain boundary conductivity of 6.25 × 10 −4 S cm −1 at room temperature. 38 Mohaghegh et al 39 reported a maximum bulk conductivity of 1.38 × 10 −3 S cm −1 at 25 °C for the Fe 2 O 3 -added glass−ceramic Li 2 O−TiO 2 −P 2 O 5 − x(Fe 2 O 3 ) (x = 5, GC 5 ). Addition of Fe 2 O 3 into glasses is speculated to loosen the framework structure and promote crystallinity of glasses to enhance ionic conductivity.…”

Inorganic solid lithium ion conductors are potential candidates as replacement for conventional organic electrolytes for safety concerns. However, achieving a Li-ion conductivity comparable to that in existing liquid electrolytes (>1 mS cm–1) remains a challenge in solid-state electrolytes. One of the approaches for achieving a desirable conductivity is doping of various elements into the lattice framework. Our discussion on the structure and conductivity of crystalline Li-ion conductors includes description of NAtrium Super Ionic CONductor (NASICON)-type conductors, garnet-type conductors, perovskite-type conductors, and Lithium Super Ionic CONductor (LISICON)-type conductors. Moreover, we discuss various strategies currently used to enhance ionic conductivity, including theoretical approaches, ultimately optimizing the electrolyte/electrode interface and improving cell performance.

“…Thus, the addition of Fe2O3 inside the glassy network, leads to a potential expansion of the present amorphous matrix. Thus, this behavior occurs when Fe2O3 acts as a glass former and strengthens the structural bonds of the glass [35].…”

The relationships between the properties and structure of xFe2O3-(40-x)K2O-10MoO3-50P2O5 glasses have been reported in this paper. Homogeneous glasses are formed for different Fe2O3 contents. The density and molar volume evolution of these glasses shows that Fe2O3 acts as a glass former and strengthens the structural bonds of the glass. Experimental 57Fe Mössbauer spectroscopy graphs suggest the existence of divalent Iron (FeII) and trivalent Iron (FeIII). The boost in chemical durability agrees with the growth in glass transition temperature due to more powerful bonding in the structural network. P-O-Fe bonds replace P-O-P bonds when Fe2O3 is present in the phosphate network.
