AbstractSuperionic solid electrolytes are key to the development of advanced solid-state Li batteries. In recent years, various materials have been discovered, with ionic conductivities approaching or even exceeding those of carbonate-based liquid electrolytes used in high-performance Li-ion batteries. Among the different classes of inorganic solid electrolytes under study, lithium thiophosphates are one of the most promising due to their high Li-ion conductivity at room temperature and mechanical softness. Here, we report about the effect of synthesis parameters on the crystallization behavior and charge-transport properties of Li4PS4I. We show that thermally induced crystallization of Li4PS4I (P4/nmm), starting from the glassy phase 1.5Li2S–0.5P2S5–LiI, adversely affects the material’s conductivity. However, both conductivity and crystallization temperature can be significantly increased by applying pressure during the preparation.

Sol Gel Synthesis

Organic/inorganic hybrid membranes that are based on GTT (GPTMS-TMES-TPTE) system while using 3-Glycidoxypropyl-trimethoxysilane (GPTMS), Trimethyletoxisilane (TMES), and Trimethylolpropane triglycidyl ether (TPTE) as precursors have been obtained while using a combination of organic polymerization and sol-gel synthesis to be used as electrolytes in Li-ion batteries. Self-supported materials and thin-films solid hybrid electrolytes that were doped with Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) were prepared. The hybrid network is based on highly cross-linked structures with high ionic conductivity. The dependency of the crosslinked hybrid structure and polymerization grade on ionic conductivity is studied. Ionic conductivity depends on triepoxy precursor (TPTE) and the accessibility of Li ions in the organic network, reaching a maximum ionic conductivity of 1.3 × 10−4 and 1.4 × 10−3 S cm−1 at room temperature and 60 °C, respectively. A wide electrochemical stability window in the range of 1.5–5 V facilitates its use as solid electrolytes in next-generation of Li-ion batteries.

Our results reveal that the Li-ion conductivity of LGPS increases with decreasing grain volume. For the smallest nanometric grain size, the Li-ion conductivity at room temperature is three times higher that of the bulk system. These findings reveal that nanosizing LGPS and related solid electrolytes could be an effective approach for enhancing their Li-ion conductivity.</div>

With the emergence of non-conventional energy resources and development of energy storage devices, serious efforts on lithium (Li) based rechargeable solid electrolyte batteries (Li- SEBs) are attaining momentum due to their potential as a safe candidate to replace state-of-the-art conventionally existing flammable organic liquid electrolyte-based Li-ion batteries (LIBs). However, Li-ion conduction in solid electrolytes (SEs) has been one of the major bottlenecks in large scale commercialization of next-generation Li-SEBs. Here, in this review, various challenges in the realization of high-performance Li-SEBs are discussed and recent strategies employed for the development of efficient SEs are reviewed. In addition, special focus is laid on the ionic conductivity enhancement techniques for inorganic (including ceramics, glasses, and glass-ceramics) and polymersbased SEs. The development of novel fabrication routes with controlled parameters and highperformance temperature optimized SEs with stable electrolyte-electrode interfaces are proposed to realize highly efficient Li-SEBs.
