Microstructural effects on the superionic conductivity of a lithiated glass-ceramic

Lithium anode for lithium-air secondary batteries

“…The linear Warburg element following the semicircle may be attributed to specimen-electrode interaction [10]. The electrical conductivity of the LATP plate at 25 • C is estimated to be 1 × 10 −4 S cm −1 for the total and 4.5 × 10 −4 S cm −1 for the bulk, which is comparable with those previously reported [10][11][12]. The samples immersed in water for 1 month show a dispersed semicircle and a steeper straight line corresponding to the onset of finite length diffusion.…”

Ionic conduction through heterogeneous solids: Delineation of the blocking and space charge effects

“…It was then annealed in air at 550 • C for 2 h and subsequently furnace cooled. The annealed glass was crystallized at 950 • C for 12 h. This crystallization treatment led to the high conductivity LATP glass-ceramic material [7]. The LATP glass-ceramic was powdered into fine particle size of 1-75 m. This particle size distribution was obtained by screening the hand ground LATP powder.…”

“…AlPO 4 phase is also present in the microstructure, primarily at the grain boundaries. Further information on the crystal chemistry and properties of the LATP glass-ceramic can be found elsewhere [7]. Fig.…”

Composite effect in superionically conducting lithium aluminium germanium phosphate based glass-ceramic

“…In another paper, Xu et al [10] (1.09 × 10 −3 S cm −1 ) in a similar material. The specimen was prepared by mechanically milling nano-sized Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 glass-ceramic and subsequently sintering a pressed specimen at 900 • C for 6 h. High conductivity glass-ceramic material based on the Li 2 O-Al 2 O 3 -TiO 2 -P 2 O 5 system primarily consisting of Li 1+x Ti 2−x Al x (PO 4 ) 3 (x ∼ 0.3) phase-a derivative of the LiTi 2 (PO 4 ) 3 structure was also prepared, characterized, and reported by Thokchom and Kumar [11].…”
