“…Nonetheless, Sn anodes exhibit low reduction potentials (∼0.1 V vs Na/Na + ), and thus, it is important to select and design solid electrolytes with good reduction stability to serve as the anolyte to ensure stable long-term cycling. Extensive exploration has led to the discovery of several SSE materials with Na + conductivities comparable to many liquid electrolytes at ambient temperature. − Oxide SSEs have previously been explored due to their wide electrochemical stability windows and high ionic conductivities. , However, due to significant grain boundary resistances, which require high-temperature sintering to mitigate, their application in Na-ASSBs remains limited . Sulfide-based SSEs have been introduced to overcome the need for high-temperature processability, while retaining high ionic conductivities, and have recently been shown to work well in polymer composites to further improve the processability of the separator layers. − Additionally, chloride-based materials have been explored due to their tolerance to highly oxidative potentials (up to ∼4.2 V vs Na/Na + ) and high ionic conductivity, along with practical room temperature processability. , Recently, sodium borohydride SSEs have been introduced as some of the fastest Na + conductors at room temperature. − Yet, it remains unclear how stable, if at all, these SSE materials are when in direct contact with the anode.…”

All-solid-state batteries have recently gained considerable attention due to their potential improvements in safety, energy density, and cycle-life compared to conventional liquid electrolyte batteries. Sodium all-solid-state batteries also offer the potential to eliminate costly materials containing lithium, nickel, and cobalt, making them ideal for emerging grid energy storage applications. However, significant work is required to understand the persisting limitations and long-term cyclability of Na all-solid-state-based batteries. In this work, we demonstrate the importance of careful solid electrolyte selection for use against an alloy anode in Na all-solid-state batteries. Three emerging solid electrolyte material classes were chosen for this study: the chloride Na2.25Y0.25Zr0.75Cl6, sulfide Na3PS4, and borohydride Na2(B10H10)0.5(B12H12)0.5. Focused ion beam scanning electron microscopy (FIB-SEM) imaging, X-ray photoelectron spectroscopy (XPS), and electrochemical impedance spectroscopy (EIS) were utilized to characterize the evolution of the anode–electrolyte interface upon electrochemical cycling. The obtained results revealed that the interface stability is determined by both the intrinsic electrochemical stability of the solid electrolyte and the passivating properties of the formed interfacial products. With appropriate material selection for stability at the respective anode and cathode interfaces, stable cycling performance can be achieved for Na all-solid-state batteries.

“…The development of all-solid-state electrochemical energy storage systems that take advantage of Li + as an ionic charge carrier requires ceramic electrolytes with outstanding transport characteristics and electrochemical properties. − Although known since many decades, NaSICON (Na-ion Super Ionic CONductor) or LiSICON-type materials − offer a rich playground for cation substitution strategies , to increase Na + and Li + ion dynamics and to manipulate their electrochemical stability against Na and Li metals. Hence, NaSICON-type ceramics belong to the most recognized groups with candidates that might serve as future solid electrolytes in all-solid-state Li batteries …”

NaSICON-type rhombohedral LiHf 2 (PO 4 ) 3 (LHP) is regarded as a quite promising solid electrolyte for future all-solid-state Li-ion batteries. Appropriate aliovalent substitution is, however, necessary to achieve high ionic conductivities. A clear-cut understanding of the substitution effects on microscopic Li + ion dynamics is necessary to optimize its conduction properties. To advance in the field, we prepared a series of Ga-bearing Li 1+x Hf 2−x Ga x (PO 4 ) 3 (Ga-LHP) samples (x = 0, 0.1, ... 0.4, 1.0) to comprehensively investigate the relationship between composition and Li + ion dynamics. 7 Li and 31 P NMR helped us characterize the extent of structural disorder introduced through the replacement of Hf by Ga. In a complementary way, we compare our results from broadband conductivity spectroscopy with those obtained from time-domain NMR measurements being sensitive to long-range ion transport and to the elementary Li + jump processes. This methodical approach allowed us to trace ion dynamics over a wide length scale. It turned out that the sample with a Ga content x of only 0.1 (89.3% relative density) showed the highest bulk conductivity of 0.45 mS cm −1 (0.24 eV). Importantly, activation energies as deduced from spin−lattice relaxation NMR point to activation energies ranging from 0.15 to 0.23 eV, revealing a rather flat potential landscape to which the ions are subjected in the different forms of Ga-LHP. To test its electrochemical applicability in allsolid-state batteries, we used cyclic voltammetry, Li plating−stripping experiments, and galvanostatic cycling measurements with current densities of up to 0.1 mA cm −2 . An electrochemical stability window of 2.4 to 4.6 V, a critical current density of at least 25 mA cm −2 , and a long cycle life of more than 1900 charge/discharge cycles (60 °C) make Li 1.1 Hf 1.9 Ga 0.1 (PO 4 ) 3 , with a slight amount of Ga incorporated, indeed a highly promising alternative to current solid electrolytes.
