“…In Table 2, we show values of Angell's decoupling indexes for Li 2 S-Sb 2 S 3 -P 2 S 5 glassy system (ternary and doped) and some similar systems [4][5][6][7][8][9][10][11][12][13]. The studied glasses and most of the common glasses have high R t values (10 10 -10 14 ), so the movements of the monovalent cations on these glasses are strongly decoupled from structural relaxations characteristic at glass transition temperatures.…”

“…It is suggested that electronic conductivity remains low (because band gap enhancement, if any, is not easy to detect one on glassy samples) and ionic conductivity becomes the dominant conduction mechanism as Li + is the most mobile specie present in this ternary system. A comparison study of composition with predominant ionic conductivities (30-50% Li 2 S) with glasses belonging to the other chalcogenide lithium [4][5][6][7][8][9][10][11][12][13] conductors (Fig. 4) shows that the Li 2 S-Sb 2 S 3 -P 2 S 5 glassy system presents the following features: first, DC room temperature conductivities s 25 C ð Þ are comparable to those of the Li 2 S-As 2 S 3 system (following extrapolation line); second, activation energies (E a ) are situated on the 0.3-0.6 eV interval characteristic of the fast ion conduction; however, the Li 2 S-Sb 2 S 3 -P 2 S 5 glassy system presents the largest values and it is reflected on lower conductivity values.…”

“…); a network modifier as M 2 X (where M=Li, Ag, or Tl and X=O or S), and in some cases a doping salt (lithium halides, LiX, or lithium oxy-salts such as Li 3 PO 4 , Li 2 SO 4 , etc.). Several compositions had been found to be excellent lithium-ion conductors, for example, the classic system Li 2 S-P 2 S 5 -LiI [4] and some of the newest as Li 3 PO 4 -Li 2 S-SiS 2 [5], which are both used in commercially marketed solid state batteries [6]. We can also mention systems like Li 2 S-GeS 2 [7][8][9], Li 2 S-P 2 S 5 [10][11][12], Li 2 S-B 2 S 3 -LiI [13], etc.…”

New sulfide glasses in the Li 2 S-Sb 2 S 3 -P 2 S 5 system have been prepared by classical quenching technique where glassy domain remains up to 50% molar addition of Li 2 S and electrical conductivities have been determined by impedance spectroscopy. Room temperature DC conductivity vs Li 2 S content exhibits two regions implying different conductivity mechanisms. The compositions of low lithium content presented low electronic conductivities close to 0.01 μS/cm at room temperature (due to Sb 2 S 3 semiconducting properties). The compositions of medium lithium content could result to mixed ionic-electronic conductors with predominant ionic conductivity with a maximum close to 1 μS/cm; Arrhenius behavior is found between 25°C and T g for all glasses, but activation energy is found to be somehow above most similar systems. A comparative study with glasses belonging to the other chalcogenide systems has been undertaken and values of the decoupling index are reported, and in order to validate conductivity data, a circuit equivalent circuit was proposed and fitted parameters were calculated with good agreement.

Priority and Prospect of Sulfide‐Based Solid‐Electrolyte Membrane

et al. 2023

View full text Add to dashboard Cite

All‐solid‐state lithium batteries (ASSLBs) employing sulfide solid electrolytes (SEs) promise sustainable energy storage systems with energy‐dense integration and critical intrinsic safety, yet they still require cost‐effective manufacturing and the integration of thin membrane‐based SE separators into large‐format cells to achieve scalable deployment. This review, based on an overview of sulfide SE materials, is expounded on why implementing a thin membrane‐based separator is the priority for mass production of ASSLBs and critical criteria for capturing a high‐quality thin sulfide SE membrane are identified. Moreover, from the aspects of material availability, membrane processing, and cell integration, the major challenges and associated strategies are described to meet these criteria throughout the whole manufacturing chain to provide a realistic assessment of the current status of sulfide SE membranes. Finally, future directions and prospects for scalable and manufacturable sulfide SE membranes for ASSLBs are presented.

Unveiling the Growth Mechanism of the Interphase between Lithium Metal and Li₂S‐P₂S₅‐B₂S₃ Solid‐State Electrolytes

Chalcogenides with high ionic conductivity and appropriate mechanical properties are promising solid‐state electrolytes (SSEs) to substitute current liquid electrolytes in lithium‐ion batteries. Yet, their practical applications in all‐solid‐state batteries are still retarded by both the low critical current density and the inferior interfacial stability toward electrodes. In this work, a series of superior SSEs, that is, Li2S‐P2S5‐B2S3 electrolytes, are developed via a ball‐milling and then melt‐quenching strategy. These SSEs exhibit a high critical current density of 1.65 mA cm−2 and a long cycling life of over 300 h. In addition, the evolution mechanism of the interphase between SSEs and metallic lithium is revealed via operando electrochemical impedance spectroscopy, depth‐profiling XPS, and in situ Raman spectroscopy. The structural and chemical heterogeneities are found to be the main origins of the continual interphase evolution. The resulting “multi‐layer mosaic like” interphase facilitates the suppression of Li dendrite growth, and hence, prolongs the lifetime of lithium‐ion all‐solid‐state batteries. In addition, the preparation technique of SSEs developed in the present work is feasible for scale‐up production.
