Fig. 3: Quest for highest Li-ion conductivity in inorganic solids.
From: Solid state chemistry for developing better metal-ion batteries
The overall equation defining the ionic conductivity σ is shown together with a schematic of the activation energy barrier corresponding to the hopping of ions from site to site within the crystal structure (a, b) together with the most favorable migration path between two tetrahedral sites T1 and T2 in the b.c.c. anionic structure (c). Development of solid electrolytes over times together with their superionic conductivities (in S·cm−1) indicated in the parentheses (d).
