“…Synthesis of Battery Materials : The Na-β′′-Al 2 O 3 electrolyte was prepared by a two-step NaAl 5 O 8 -LiAl 5 O 8 reaction synthesis procedure as described in Li et al [ 25 ] Precursor NaAl 5 O 8 was fi rst synthesized from a sol-gel method. Stoichiometric amounts of Al(NO 3 ) 3 ·9H 2 O and NaNO 3 in 60% excess over stoichiometry were fi rst dissolved into DI water with citric acid as the complexing agent.…”

5380 www.MaterialsViews.com wileyonlinelibrary.com e.g. lithium-ion batteries (LIBs), is the cost of lithium. Lithium is a light element neither earth-abundant (ranked the 25 th of the most abundant elements) nor evenly distributed geologically on the earth. It is, therefore, a relatively expensive element, roughly 30 times more expensive than sodium, another light alkaline element. [ 1,2 ] Based on these facts, it would seem to be rational to develop all-solid-state sodium-ion batteries (NIBs) that are advantageous in both cost and safety, even though they may exhibit slightly lower Nernst potential than LIBs due to thermodynamic reasons. In fact, NIBs have been investigated for nearly half a century. The most successful demonstration is the sodium-sulfur (NAS) and ZEBRA rechargeable batteries operated at 250-350 °C, in which a ceramic Na + -conductor, Na-β′′-Al 2 O 3 , is used as the electrolyte to separate two molten Na/Na x S and Na/NiCl 2 anode/ cathode pairs for NAS and ZEBRA, respectively. [ 1,[3][4][5] However, active molten Na is a chemical hazard to safe operations. Extra safety measures have to be taken into account, which in turn increases the overall system cost. Furthermore, the molten state of Na needs to be maintained all the time, even when the battery is not in operation, in order to avoid a disastrous "freezing" effect. This requirement costs an additional >10% of its own capacity per day. [ 6 ] The NAS/ZEBRA battery technology, therefore, will need to overcome the "molten electrodes" barriers in order to become a safe and commercially viable product. [ 3 ] On the other hand, NIBs have also been demonstrated with good room-temperature performance in recent years with liquid electrolytes and solid-state electrodes. [7][8][9][10] The all-solid-state rechargeable batteries have been considered the next-generation energy storage devices because of their unequivocal advantages over liquid-based counterparts in thermal and chemical stabilities, mechanical robustness, cost and safety. [11][12][13] The all-solid-state Li + and Na + rechargeable batteries are the most studied systems due to the availability of solid Li + /Na + conductors and a long history of research. So far, all-solid-state LIBs have been demonstrated with solid Li + -conductors such as garnet Li 5 La 3 M 2 O 12 (M = Nb, Ta), [ 14,15 ] perovskite La 0.5 Li 0.5 TiO 3[ 16 ] and thio-LISICON Li 3.25 Ge 0.25 P 0.75 S 4 [ 17,18 ] as the electrolyte, LiCoO 2 as the cathode and Li/C as the anode. [ 15,18,19 ] A multilayered ceramic-based LIB comprising of a Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 as the electrolyte and Li 3 V 2 (PO 4 ) 3 as both cathode and anode has recently been fabricated by spark plasma sintering. [ 20,21 ] Similarly, all-solid-state NIBs have also been reported with NASICON (Na 3 Zr 2 Si 2 PO 12 ) as the electrolyte, A major challenge to the development of the next-generation all-solid-state rechargeable battery technology is the inferior performance caused by insuffi cient ionic conductivity in the electrolyte and poor mixed io...

“…The fact that the increase of binder system content increased slurry viscosity, indicated that the binder interacted as an adhesive agent without replacing dispersant from the powder surface. 2,20 Thus the dispersant is acting as intended and not accumulated between binder polymeric chains, deteriorating mechanical properties. Pseudoplasticity, required for tape casting, was typical for all prepared slurries (Fig.…”

“…Previous studies have reported the synthesis of amorphous Na-Al-O film by using molecular beam epitaxy (MBE) [20] and rf-magnetron sputtering [21]. Besides, Li + /Mg 2+ -doped Na-β-alumina films have been prepared by various methods, including tape-casting process [22], solid-state reaction [23] and chemical reaction between sapphire substrate and gaseous alkali-species from the Na/Li-β-alumina powders surrounding the sapphire substrate [24,25]. Although the doping of alkali and alkaline earth metals, such as Li + , K + , and Mg 2+ , stabilizes the structure of β-alumina at low temperatures, the synthesis of Li + /Mg 2+ -doped Na-β-alumina films often requires high temperatures above 1573 K, which results in the loss of alkali and alkaline earth metals.…”
