“…At lower concentration of oxides, the ionic conductivity is increased by the change of charge carrier distribution in the composite caused by the surface acidity of oxides. With a high concentration of oxides in the system, the oxides particles block the motion of Li ions (Figure d) . Similarly, Rangasamy et al studied the composite of Li 7 La 3 Zr 2 O 12 (LLZO, conductivity 4 × 10 −4 S cm −1 at room temperature) and β‐Li 3 PS 4 .…”

Due to their high ionic conductivity and adeciduate mechanical features for lamination, sulfide composites have received increasing attention as solid electrolyte in all-solid-state batteries. Their smaller electronegativity and binding energy to Li ions and bigger atomic radius provide high ionic conductivity and make them attractive for practical applications. In recent years, noticeable efforts have been made to develop high-performance sulfide solid-state electrolytes. However, sulfide solid-state electrolytes still face numerous challenges including: 1) the need for a higher stability voltage window, 2) a better electrode-electrolyte interface and air stability, and 3) a cost-effective approach for large-scale manufacturing. Herein, a comprehensive update on the properties (structural and chemical), synthesis of sulfide solid-state electrolytes, and the development of sulfide-based all-solid-state batteries is provided, including electrochemical and chemical stability, interface stabilization, and their applications in high performance and safe energy storage.

“…1c. For the combination of an oxide SE with a thiophosphate one-Li 7 La 3 Zr 2 O 12 (LLZO) and β-Li 3 PS 4 (LPS) for example-the processing temperature can be reduced compared to the pure oxide and the ionic conductivity is enhanced because of space-charge effects at the interface [35,36]. SE fillers are also commonly used in polymer matrices [37][38][39][40].…”

“…Even less focus was put on the interfacial properties between two different SEs in batteries [8,35,36]. Only resistances and activation energy were reported, as well as X-ray diffraction (XRD) data to show the absence of decomposition of the bulk materials [35,36]. To gain knowledge about the actual contribution of the interfacial transport between both SEs, a model system is necessary.…”

Hybrid battery cells combining liquid electrolytes (LEs) with inorganic solid electrolyte (SE) separators or different SEs and polymer electrolytes (PEs), respectively, are developed to solve the issues of single-electrolyte cells. Among the issues that can be solved are detrimental shuttle effects, decomposition reactions between the electrolyte and the electrodes, and dendrite propagation. However, the introduction of new interfaces by contacting different ionic conductors leads to other problems, which cannot be neglected before commercialization is possible. The interfaces between the different types of ionic conductors (LE/SE and PE/SE) often result in significant charge-transfer resistances, which increase the internal resistance considerably. This review highlights studies evaluating the interfacial resistances and activation barriers in such systems to present an overview of the issues still hampering hybrid battery systems. The interfaces between different SEs in hybrid all-solid-state batteries (SSBs) are considered as well. In addition, a short summary of physicochemical models describing heteroionic interfaces-interfaces between two different ion conductors-is given in an attempt to explain high interface resistances. In doing so, we hope to inspire future work on the crucial topic of interface optimization toward better SSBs.

“…It was found that, at most, the addition of 10% TiO 2 could raise the RT ionic conductivity of 85PEG–15Mg(NO 3 ) 2 to 10 −4 S cm −1 . [50a] Liang and co‐workers compared the effects of ion‐conducting fillers (Li 6 ZnNb 4 O 14 (LZNO)) and nonconducting fillers (Al 2 O 3 , SiO 2 ) on Li + mobility in β‐Li 3 PS 4 (LPS) solid‐state electrolyte . For the 10:90 (LZNO:LPS) composite, the ionic conductivity reached 2.44 × 10 −4 S cm −1 and was the highest among the three LPS–filler composites, indicating the unique interface effect between the LZNO and LPS.…”

devices and for various types of consumer electronics. All-solid-state rechargeable batteries (ASSBs) utilizing solid-electrolyte separators rather than combustible liquid electrolytes possess the inherent advantages of enhanced safety and stability for state-of-the-art battery technologies. [1] Recently, ASSBs have attracted a resurgence of interest as ideal candidates for the next generation of electrochemicalenergy-storage devices. The superiority of ASSBs could be ascribed to the distinctive attributes of solid-state electrolytes (SSEs), including high Li-ion transference number and safety, and comparable ionic conductivity to their liquid counterparts. [2] The adoption of SSEs could offer new opportunities for the high-temperature electrical-energy-storage market and pave the way for the utilization of high-capacity electrodes, such as Li, Na, and sulfur. [2c,3] In contrast, in conventional batteries employing liquid electrolytes, the highcapacity electrodes may meet with detrimental side reactions, causing problems such as dendrite growth, reactivity, and/ or dissolution in the solvent. [4,5] With the construction of rigid solid electrolyte separators and stable interfaces in ASSBs, dendrite growth can be effectively mitigated, thus improving the safety of the batteries. [4,6] Owing to these benefits, in battery research, the number of studies on fabricating superionic SSEs has grown rapidly. Despite great progress gained these years, issues Borohydride solid-state electrolytes with room-temperature ionic conductivity up to ≈70 mS cm −1 have achieved impressive progress and quickly taken their place among the superionic conductive solid-state electrolytes. Here, the focus is on state-of-the-art developments in borohydride solid-state electrolytes, including their competitive ionic-conductive performance, current limitations for practical applications in solid-state batteries, and the strategies to address their problems. To open, fast Li/Na/Mg ionic conductivity in electrolytes with BH 4 − groups, approaches to engineering borohydrides with enhanced ionic conductivity, and later on the superionic conductivity of polyhedral borohydrides, their correlated conductive kinetics/thermodynamics, and the theoretically predicted high conductive derivatives are discussed. Furthermore, the validity of borohydride pairing with coated oxides, sulfur, organic electrodes, MgH 2 , TiS 2 , Li 4 Ti 5 O 12 , electrode materials, etc., is surveyed in solid-state batteries. From the viewpoint of compatible cathodes, the stable electrochemical windows of borohydride solid-state electrolytes, the electrode/electrolyte interface behavior and battery device design, and the performance optimization of borohydride-based solid-state batteries are also discussed in detail. A comprehensive coverage of emerging trends in borohydride solid-state electrolytes is provided and future maps to promote better performance of borohydride SSEs are sketched out, which will pave the way for their further development in the field of energy stora...
