Paddle wheel mechanism in lithium sulfates: Arguments in defense and evidence against
TL;DR: In this paper, a number of factors contribute to facilitating intersite mobility of cations in the enhancement of ionic conductivity, including the facility of Li + passage through a larbe bottleneck size of the highly supple lattice of Li 2 SO 4.

Electrical conductivity of superionic solid solutions of Na2SO4 with Mx (XO4)y -[M=Na, K, Rb, Cd, GdandX=W, Mo, S, Si;x=1, 2, 4 andy=1, 3]
TL;DR: In this article, electrical conductivity data were reported for solid solutions of Na 2 SO 4, K 2 WO 4, Na 2 WSO 4, Na 2 MoO 4, Rb 2 SO4, Na 4 SiO 4-4 and Gd 2 (SO 4 ) 3, and showed conclusively that the anion-rotation "cogwheel" mechanism does not contribute to the cationic conductivity.

Rotating sulfate ion contribution to electrical conductivity in Li2SO4 and LiNaSO4
TL;DR: In this article, the results of a.c. electrical conductivity measurements on Li2SO4 incorporating WO2-4 as guest ion in SO 2-4 sublattice and on LiNaSO4 with SiO4-4 ion as a guest ion was presented.

Ion transport in sulfates: Percolation mechanism versus paddle-wheel mechanism
TL;DR: In this article, a percolation ion transport mechanism in a lattice structure of increased free volume or openness is proposed to explain the high mobility of Li2SO4-based compounds.

Sodium ion-conducting solid electrolytes in the system Na3PO4Na2SO4
TL;DR: In this article, the phase diagram for the system Na3PO4Na2SO4 is given together with lattice parameters of the γ solid solutions, and the conductivity increases with increasing x and reaches a maximum at x = 0.5 to 0.6.
