          We have performed atheoretical study of the Li/Li6PS5Cl interface and showed the ability of theapplied computational methods to properly describe the chemical processes thatoccur at the interface. After a 500 ps ab initio molecular dynamics simulation,we find that the Li/Li6PS5Cl interface decomposes with formation of multiplephases and that the main decomposition products are Li2S, Li3P, LiCl, andpossibly LiP. These findings are in good agreement with reported experimentaldata. The observed quick decomposition is attributed to the weak bondingbetween P and S. On the basis of this and earlier obtained experimentalresults, we conclude that the chemical instability may be an intrinsic problemof P S-based solid electrolytes when they are in contact with Li-metal. Ourresults validate the effectiveness of the available computational tools toreach a deeper insight into the evolution of interfacial structures andproperties prior to experiment.

          Bulk-typeall-solid-state lithium-ion batteries (ASLBs) have the potential to be superiorto conventional lithium-ion batteries (LIBs) in terms of safety and energydensity. Sulfide SE materials are key to the development of bulk-type ASLBsbecause of their high ionic conductivity (max of approximately 10-2 S cm-1) anddeformability. However, the severe reactivity of sulfide materials towardcommon polar solvents and the particulate nature of these electrolytes poseserious complications for the wet-slurry process used to fabricate ASLBelectrodes, such as the availability of solvent and polymeric binders and theformation of ionic contacts and networks. In this work, we report a newscalable fabrication protocol for ASLB electrodes using conventional compositeLIB electrodes and homogeneous SE solutions (Li6PS5Cl (LPSCl) in ethanol or0.4LiI-0.6Li4SnS4 in methanol). The liquefied LPSCl is infiltrated into thetortuous porous structures of LIB electrodes and solidified, providing intimateionic contacts and favorable ionic percolation. The LPSCl-infiltrated LiCoO2and graphite electrodes show high reversible capacities (141 and 364 mA h g-1)at 0.14 mA cm-2 (0.1 C) and 30 degrees C, which are not only superior to thosefor conventional dry-mixed and slurry-mixed ASLB electrodes but also comparableto those for liquid electrolyte cells. Good electrochemical performance ofASLBs employing the LPSCl-infiltrated LiCoO2 and graphite electrodes at 100degrees C is also presented, highlighting the excellent thermal stability andsafety of ASLBs.

          The aim of achievinghigh-energy, long-life, safe and low cast storage batteries has broughttremendous scientific attention in the last decade, resulting in significantimprovements in the stored energy of cathodes and anodes particularly inlithium-based battery technology. However, presently available lithium-iontechnology cannot satisfy the increasing demand for energy density. Li-Sbattery is a typical example, which can offer theoretically a fivefold increasein energy density compared with conventional lithium rechargeable batteries.Despite significant advances, there are challenges to its wide-scaleimplementation, which include dissolution of intermediate polysulphide reactionspecies into the electrolyte when liquid polysulphide is used as cathodes.Another problem is preparation of polysulphides. Here we report a novel approachto replace the liquid electrolyte with solid lithium conducting membranes,Argyrodite (Li6PS5X(X = Cl,Br)) and Li10GeP2S12 solid electrolytes to mitigatethe problem. Among the three solid electrolyte membranes Li10GeP2S12 exhibitedhigh first discharge specific capacity of 1435 (+/- 3) mAh g(-1) at 0.5 C rate.
