Lithium phosphorus sulfuric oxide nitride (LiPSON) is prepared by radio frequency (RF) sputtering using a sputter target with compositions of 50 wt% Li3PO4 and 50 wt% Li2SO4. Knowledge about the present phases at the solid electrolyte–lithium anode interface, the so‐called solid electrolyte interphase (SEI), is achieved by performing an in situ sputtering of metallic lithium on the electrolyte and subsequently measuring the chemical bonding by X‐ray photoelectron spectroscopy (XPS). Information about the SEI is of essential interest to understand the process of lithium‐ion conduction in the half cell. Therefore, the information about the formation of lithium phases in the SEI is crucial.

“…In fact, the nitrogen atoms can enter the glass network as di‐coordinated (=N–), and tricoordinated (>N–) nitrogen . The role of divalent and trivalent nitrogen on oxynitride glass structure has been discussed by several authors; however, the mechanisms are not yet completely understood and it has being also, recently, investigated in nitrided thin films …”

“…Ammonolysis is carried out by a gradual replacement of oxygen by nitrogen involving a mixed reaction/diffusion rate‐limiting mechanism caused in the network structure . The most studied parameters to control the nitrogen incorporation in phosphate glasses are temperature, time, and ammonia flow . However, some relevant parameters that may influence the nitrogen uptake were not well defined such as the initial mass of the base glass and if the material is in powder or bulk form, among others.…”

Metaphosphate glasses such as LiPO3 and NaPO3 are known to incorporate nitrogen in the molten state under NH3 flow to form (Li/Na)PON glasses through the reaction: (Li/Na)PO3 + xNH3 → (Li/Na)PO3−(3x/2)Nx + (3x/2)H2O, by partially replacing two‐coordinated oxygen with two‐ and three‐coordinated nitrogen. After nitridation, the glasses exhibit improved properties such as increased working range, chemical durability, and ionic conductivity. In this study, LiPO3 and NaPO3 glasses were prepared by the conventional melting and casting method and used as base glasses for the ammonolysis procedure. The nitridation processes were carried out by remelting the base glasses at temperatures up to 780°C, under a constant NH3 flow. The effects on the nitrogen content in the resulting (Li/Na)PON glasses caused by different processing times and masses of powder and/or bulk materials were investigated. Nitridation was successfully confirmed by CNHS chemical analyses, Raman spectroscopy, and Differential Scanning Calorimetry. Mass loss measurements after the ammonolysis process and Raman spectroscopy were used to quantify the nitrogen content into the glass structure. A new approach using a specific Raman normalization, (P–N<)/(O–P–O)sym, has been demonstrated as a reliable, simple, and fast way to determine the amounts of N incorporated to metaphosphate glass structures.

Lithium-sulfur (Li-S) batteries are one of the most promising next-generation battery types for their high energy density and low cost. On the other hand, safety issues and poor cyclability strongly limit practical application. Solidstate electrolytes (SSEs) can present as high ionic conductivity as aprotic electrolytes and eventually avoid the shuttle effect, which provides an ultimate solution for safe Li-S batteries with good cyclability. In this review, the recent achievements in all-solid-state Li-S batteries based on inorganic SSEs are summarized. Furthermore, the main attentions are paid to the interfaces, including metallic lithium|SSEs, SSEs|SSEs, and composite sulfur cathode|SSEs. The potential approaches to deal with these interfacial issues are proposed as well, such as composite SSEs with an asymmetric structure to enhance their compatibility with lithium anodes and sulfur cathodes, adding Li 2 O or LiF and increasing the densification to reduce the grain boundary resistance, and nanomaterials used to improve the kinetic process in cathode. Figure 3. Structures of several SSEs. a) Local structure phase diagram of Li 2 S:P 2 S 5 glass ceramics and the changes of anionic units with temperature and compositions. Only the 75Li 2 S:25P 2 S 5 glass consisting of orthothiophosphates presents good thermal stability. Reproduced with permission. [58]
