“…Some studies suggest that a narrow particle size distribution enhances ionic conductivity by increasing surface area and facilitating ion transport. 37,38 Conversely, other research indicates that a wider distribution may be beneficial. 39 Regardless of these differing views, it is generally agreed that an optimized particle size distribution is vital for achieving effective electrode-electrolyte contact and uniform interface formation.…”

This review gives a detailed overview of the challenges in using sulfide solid electrolytes in all-solid-state lithium-sulfur batteries and discusses strategies to overcome them. First, the general description of the synthetic procedure of the sulfide solid electrolytes is given, including descriptions of the potential ways for improvement of the electrolyte properties, such as ionic conductivity and air and moisture resistance. This is followed by a review of the polymer binders and matrices that can enhance the sulfide solid electrolytes mechanical strength. Subsequently, the ways to ensure the chemical stability on the anode-solid electrolyte interface are described. Finally, prototypes of the all-solid-state Li-S batteries, created by using the combination of all above-mentioned methods, are discussed.

“…Furthermore, numerous papers have been published on solid electrolytes (SEs), which are essential components of all ASSBs. Among the different types of SEs developed to date, such as oxides, polymers, sulfides, and halides, sulfide SEs are particularly promising owing to their high ionic conductivity and excellent ductility [17][18][19][20][21][22] . Several sulfide SEs show high conductivities; for example, Li7P3S11 [23] , Li10GeP2S12 [24] , Li9.54Si1.74P1.44S11.7Cl0.8 [25] , and Li5.5PS4.5Cl1.5 show conductivities of 1.2×10 −2 , 1.2×10 −2 , 2.5 × 10 −2 , and 9.4 × 10 −3 S cm −1 , respectively, at 25 ℃ [26][27][28][29][30] .…”

All-solid-state batteries (ASSBs) with adequately selected cathode materials exhibit a higher energy density and better safety than conventional lithium-ion batteries (LIBs ). Ni-rich layered cathodes are benchmark materials for traditional LIBs owing to their high energy density. Recent studies have highlighted the advantages of using crack-free, single-crystalline cathode materials in ASSBs . In this study, a scalable infiltration sheet-type process was used to fabricate composite electrodes with different cathode-material morphologies for ASSBs . Typically, crack-free single-crystalline materials exhibit a better retention performance and lower rate capability than polycrystalline cathode materials. In this study, Li6PS5Cl-infiltrated polycrystalline electrodes showed an excellent retention performance and rate capability. Galvanostatic intermittent titration technique analysis and transmission electron microscopy confirmed severe polarization and the presence of a rock-salt-structure layer in cathode particles, indicating side reactions within the layered structure of the material. In contrast, composite electrodes comprising polycrystalline cathode materials infiltrated with the solid electrolyte Li6PS5Cl showed an excellent electrochemical performance owing to intimate electrode–electrolyte interfacial contact. This study confirms the critical influence of interface engineering and material morphology on the overall performance and stability of ASSBs, and could facilitate the development of high-performance ASSBs in the future .

Solvent exchange-induced facile recrystallisation and particle size control of sulphide solid electrolytes for all-solid-state Li-ion batteries

Abstract: Practical all-solid-state Li-ion batteries (ASSLBs) require small-sized sulphide solid electrolyte (SSE) particles (SSE membranes (few microns) and composite electrodes (sub-microns)). However, particle-size reduction via mechanical crushing and classification significantly reduces...
