We have studied the ionic and thermal transport properties along with the thermodynamic key properties of a Na-ion-conducting phosphate ceramic. The system Na1+xAlxTi2−x(PO4)3 (NATP) with x = 0.3 was taken as a NASICON-structured model system which is a candidate material for solid electrolytes in post-Li energy storage. The commercially available powder (NEI Coorp., USA) was consolidated using cold isostatic pressing before sintering. In order to compare NATP with the “classical” NASICON system, Na1+xZr2(SiO4)x(PO4)3−x (NaZSiP) was synthesized with compositions of x = 1.7 and x = 2, respectively, and characterized with regard to their ionic and thermal transport behavior. While ionic conductivity of the NaZSiP compositions was about more than two orders of magnitude higher than in NATP, the thermal conductivity of the NASICON compound showed an opposite behavior. The room temperature value was about a factor two higher in NATP compared to NaZSiP. While the thermal conductivity decreases with increasing temperature in NATP, it increases with increasing temperature in NaZSiP. However, the overall change of this thermal transport parameter over the measured temperature range from room temperature up to 800 °C appeared to be relatively small.

This investigation presents mixed polyanion G-NaCu1 − x(VO)xPO4 (x = 0.1, 0.3, 0.5,0.7and 0.9 mol%) glass-based cathode material network prepared using the melt-quenching process followed by heat-treating at its Tcfor 5h to form its glass-ceramic(GC- NaCu1 − x(VO)xPO4). The best crystalline NaV2O5 (ICSD 760908) NaCu(PO4)(ICSD 581303), and Na2Cu(P2O7)(ICSD 556822) phases precipitated in the glass network during crystallization will accommodate sudden volume changes, resulting to trigger the fast diffusion of Na+ ions in the glass-ceramic network leading to fast rate capability and voltage for longer durations. The lowest charge transfer resistance Rct = 7.086x103Ω from 1st to 1000 cycles and highest retention of discharge capacity (99.71%) when the current rate is decreased from 10C to 0.1C, determines its long-term cycle life stability and rate capability more than other crystalline compounds.

“…Since then, many glass-ceramic electrolytes have been proposed using the crystallization technique. These also fall into the categories of sulfides (such as Na 3 PS 4 -Na 4 SiS 4 , Na 2.9375 PS 3.9375 Cl 0.0625 , Na 3 PS 4 -Na 4 GeS 4 , Na 3 PS 4 -NaI, Na 10 GeP 2 S 12 , and Na 3 Si x Sb 1-x S 4-y Br y ) and oxides (such as Na 1+x [Sn x Ge 2−x (PO 4 ) 3 ], Na 3+x [Zr x Sc 2-x (PO 4 ) 3 ], Na 1+y Ti 2 Si y P 3-y O 12 , (Na 2 O + NaF)-TiO 2 -B 2 O 3 -P 2 O 5 -ZrF 4 , Na 3 Zr 2 Si 2 PO 12 -NaF, Na 1+x Y y Ga x−y Ge 2−x (PO 4 ) 3 , and Na 2 O-Y 2 O 3 -SiO 2 ) and may exhibit room-temperature conductivities as high as 2.26 mS cm −1 (Na 3 Si x Sb 1-x S 4-y Br y ), but are typically reported to be near 0.1 mS cm −1 (Tanibata et al, 2014;Li et al, 2015b;Hibi et al, 2015;Ni et al, 2015;Chu et al, 2016;Gandi et al, 2018;Manchgesang et al, 2018;Tanibata et al, 2018;Tsuji et al, 2018;Nieto-Muñoz et al, 2019;Shao et al, 2019;Sundar et al, 2019;Gong et al, 2023). Sintered, crystalline thiophosphates with tungsten dopants (Na 3-x Sb 1-x W x S 4 , and Na 3-x P 1-x W x S 4 ) can attain even higher room-temperature conductivities, reaching as high as 41 mS cm −1 (Hayashi et al, 2019;Fuchs et al, 2020).…”

The need for clean, renewable energy has driven the expansion of renewable energy generators, such as wind and solar. However, to achieve a robust and responsive electrical grid based on such inherently intermittent renewable energy sources, grid-scale energy storage is essential. The unmet need for this critical component has motivated extensive grid-scale battery research, especially exploring chemistries “beyond Li-ion”. Among others, molten sodium (Na) batteries, which date back to the 1960s with Na-S, have seen a strong revival, owing mostly to raw material abundance and the excellent electrochemical properties of Na metal. Recently, many groups have demonstrated important advances in battery chemistries, electrolytes, and interfaces to lower material and operating costs, enhance cyclability, and understand key mechanisms that drive failure in molten Na batteries. For widespread implementation of molten Na batteries, though, further optimization, cost reduction, and mechanistic insight is necessary. In this light, this work provides a brief history of mature molten Na technologies, a comprehensive review of recent progress, and explores possibilities for future advancements.
