Liquid-mediated synthesis offers a new approach to producing or applying solid electrolytes (SEs) in all-solid-state Li-ion batteries (ASSLIB). Li-ion conductive Li3InCl6 (LIC) powders are synthesized using a water-mediated process in which hydrated precursor powders are dried at progressively increasing temperatures up to 200°C. The effects of drying environments, including high-vacuum (HV; 10-3 Torr), low-vacuum (LV; 10-1 Torr), Ar, and N2 (both at 1 atm), on the chem., microstructural, and ionic conductive properties of the LIC powders are investigated. Oxy-contaminations in the LIC powders are determined based on synchrotron X-ray diffraction and X-ray absorption analyses. The ionic conductivity of the produced LIC powder exhibits a profound reverse trend with the amounts of oxy contaminations, including crystal water residual and In-O oxy species, such as InOCl. The vacuum drying conditions favor the formation of smaller particles, which facilitate water removal due to a shorter diffusion length and a higher surface area, resulting in less oxy-contamination and higher ionic conductivities (HV: 2.70 mS cm-1; LV: 0.96 mS cm-1). The 1-atm drying conditions, either in Ar or N2, produce compact LIC chunks, which are unfavorable to water removal, and more oxy-contaminations, leading to nearly an order of magnitude lower conductivities (Ar: 0.39 mS cm-1; N2: 0.22 mS cm-1). The HV SE powder leads to the best electrochem. performance of a high-capacity Ni-rich Li(Ni,Mn,Co)O2SEInLi full-cell. The revealed processing-microstructure-property relationships may facilitate the synthesis of high-quality halide-based Li-ion SEs for ASSLIB applications. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Product Details of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 7447-41-8
