“…18 Moreover, density functional theory (DFT) calculations pointed towards an exceptionally high ionic conductivity around 10 −1 S cm −1 . 19 Taken together, these reports and especially the prospects of achieving high ionic conductivity in the xLi 2 S/yP 2 S 5 /zLiI system (amorphous, crystalline or both) [18][19][20][21][22][23][24] motivated us to embark on an investigation into the preparation of the glass (ceramic) phase of Li 4 PS 4 I.…”

All‐solid‐state lithium batteries have emerged as a priority candidate for the next generation of safe and energy‐dense energy storage devices surpassing state‐of‐art lithium‐ion batteries. Among multitudinous solid‐state batteries based on solid electrolytes (SEs), sulfide SEs have attracted burgeoning scrutiny due to their superior ionic conductivity and outstanding formability. However, from the perspective of their practical applications concerning cell integration and production, it is still extremely challenging to constructing compatible electrolyte/electrode interfaces and developing available scale processing technologies. This review presents a critical overview of the current underlying understanding of interfacial issues and analyzes the main processing challenges faced by sulfide‐based all‐solid‐state batteries from the aspects of cost‐effective and energy‐dense design. Besides, the corresponding approaches involving interface engineering and processing protocols for addressing these issues and challenges are summarized. Fundamental and engineering perspectives on future development avenues toward practical application of high energy, safety, and long‐life sulfide‐based all‐solid‐state batteries are ultimately provided.

“…The number of methods to improve the ionic conductivity of solid electrolytes prepared by the liquid-phase synthesis route is very limited; these methods include the addition of LiX (X = Cl, Br and I) and a thermal treatment procedure in the case of argyroditetype solid electrolytes [28][29][30][31][32]. Doping Li 3 PS 4 with oxygen (75Li 2 S•23P 2 S 5 •2P 2 O 5 ) resulted in the increase of ionic conductivity at room temperature (RT) from 1.83 × 10 −4 Scm −1 to 2.53 × 10 −4 Scm −1 [33].…”

“…In this study, 100Li 3 PS 4 •xLi 3 PO 4 solid electrolytes were prepared by liquid-phase synthesis using ethyl propionate (EP). EP was employed in this study since it was suitable for Li 3 PS 4 and Li 3 PS 4 -LiI solid electrolytes preparation [19,30]. Ultravioletvisible (UV-Vis) spectroscopy evidenced the solvation of P 2 S 5 but not of Li 3 PO 4 in EP.…”

A solid solution of a 100Li3PS4·xLi3PO4 solid electrolyte was easily prepared by liquid-phase synthesis. Instead of the conventional solid-state synthesis methods, ethyl propionate was used as the reaction medium. The initial stage of the reaction among Li2S, P2S5 and Li3PO4 was proved by ultraviolet-visible spectroscopy. The powder X-ray diffraction (XRD) results showed that the solid solution was formed up to x = 6. At x = 20, XRD peaks of Li3PO4 were detected in the prepared sample after heat treatment at 170 °C. However, the samples obtained at room temperature showed no evidence of Li3PO4 remaining for x = 20. Solid phosphorus-31 magic angle spinning nuclear magnetic resonance spectroscopy results proved the formation of a POS33− unit in the sample with x = 6. Improvements of ionic conductivity at room temperature and activation energy were obtained with the formation of the solid solution. The sample with x = 6 exhibited a better stability against Li metal than that with x = 0. The all-solid-state half-cell employing the sample with x = 6 at the positive electrode exhibited a better charge–discharge capacity than that employing the sample with x = 0.
