Effect of indium doping on thermal stability and dielectric property in sodium beta alumina solid electrolyte

Wide-temperature-range sodium-metal batteries: from fundamentals and obstacles to optimization

“…As another promising system, the optimization strategy for beta-alumina solid electrolyte is mostly based on second-phase reinforced-composite materials. 261,262 For instance, a yttria-stabilized zirconia (YSZ)-enhanced beta-alumina solid electrolyte (YSZ@BASE) (∼37 wt%) was reported by Deng and co-workers, which exhibited an ultra-low interface impedance of 3.6 Ω cm −2 at 80 °C. 263 Fig.…”
