“…Skin effect due to high frequency alternating electric-field also had no effect on surface conductivity because of the magnitudes of the conductivity values involved. Thick film surface conductivity (σ 300 • C = 1.26 × 10 −5 sq/Ω ) is far less than bulk conductivity (σ 300 • C = 2.51 × 10 −3 S/cm) reported in literature 37 . The values of conductivity and relaxation activation energies suggest that ions whilst conducting and relaxing overcome the same energy barrier.…”

Although AC conductivity measurements of NASICON is well documented in literature, thick film conductivity and ion dynamic studies, important for planar, are scarcely reported. Most thick film measurements are performed using four point probe methods (DC method) and are quite limited in that, they cant give information on ion dynamics and cannot seperate contributions from grains, grain boundaries and electrode effects. However, in this paper we report the electrical properties of NASICON, x = 1.95 thick films of different thicknesses (20-32 µm), screen printed on alumina substrates, in light of ionic dynamics using the AC conductivity formalism. Surface resistivities of thick films from impedance data in the frequency range 0.1 ≤ f (HZ) ≤ 3.2 × 10 7 is obtained. Impedance Cole-Cole plots shows grain interior and electrode effects. The hopping frequency and AC/DC conductivity are thermally activated and show Arrhenius-type behaviour, with activation energies in the range of 0.44 ≤ E a (eV ) ≤ 0.46. Scaling in conductivity and Modulus shows that the relaxation mechanisms are independent of temperature and film thickness. Conductivity was independent of film thickness at high temperatures. SEM reveals that there is a minimum thickness for which NASICON on alumina substrate can be printed and used in high temperature planar electrochemical devices.

“…This term is now used for all ceramic materials with the same crystal structure and the general composition A 1 + 2x + y + z M (II) x M (III) y M (IV) 2 − x − y Si z P 3 − z O 12 where A is usually a mono-or divalent cation (here, A = Na) and M are divalent, trivalent or tetravalent cations; P can also be substituted with Si or As. The materials belonging to the NASICON family are very attractive because of their compositional diversity leading to many possible applications, such as electrode materials or solid electrolytes in batteries as tested in an all-NASICON battery by Lalère et al [3], Cl 2 and CO 2 sensors [4,5], or photoluminescent devices [6]. The conductivity of the NASICON materials is strongly related to their Na concentration and their crystallographic structure, which is influenced by the size of the M cations.…”

“…Sodium-ion batteries offer a viable, lower cost alternative to lithium-ion batteries for grid-level storage [1,2]. In particular, all-solidstate sodium-ion batteries with a ceramic Na 3 Zr 2 Si 2 PO 12 (NASICON) electrolyte were demonstrated to be a safe, inexpensive, and reliable alternative to other battery chemistries [3,4]. Furthermore, sodium-air and sodium-sulfur batteries with a NASICON electrolyte have also shown promise as highdensity energy storage devices [5,6].…”

Doping the zirconium site in NASICON (Na 3 Zr 2 Si 2 PO 12 ) with lower valent cations enhanced the ionic transport of the material. exhibited a higher bulk conductivity than undoped Na 3 Zr 2 Si 2 PO 12 at room temperature. A decrease in the low temperature activation energy for all doped NASICON was observed, which helped contribute to the higher room temperature conductivity. The lower activation energy and enhanced conductivity of doped materials were a result of alterations in the NASICON structure. The charge imbalance created by aliovalent substitution increased the sodium in the lattice resulting in more charge carriers with better mobility. Furthermore, the conductivity was optimized by the ionic radius of the species in the zirconium site. Ultimately, NASICON doped with a +2 oxidation state cation having an ionic radius of approximately 0.73 Å (Zn and Co) attained a maximum in conductivity. Zn-doped NASICON displayed the greatest room temperature bulk conductivity of 3.75×10 −3 S/cm, while Co-doped NASICON demonstrated the greatest total conductivity of 1.55×10 −3 S/cm.
