Solid-state electrolytes (SSEs) play a vital role in the development of high-energy all-solid-state batteries. However, most adopted mechanical ball milling and/or high-temperature annealing are ineffective approaches for large-scale synthesis. Herein, a universal and scalable hydrate-assisted strategy for the synthesis of oxychloride SSEs is developed based on the chemical reaction among alkali chlorides, AlCl3, and AlCl3·6H2O. The synthesized aluminum-based oxychloride SSEs possess a high Li+ conductivity over 1 mS cm-1 at 30 °C. The final aluminum-based oxychloride SSEs are structurally heterogeneous with nm-sized LiCl-like and LiAlCl4 crystallites and large amounts of amorphous [AlaObClc](2 b + c -3 a )- components. Faster local mobility of Li+ ions in amorphous structures is verified and is attributable to weakened Li+-X- interactions ensured by the [AlaObClc](2 b + c -3 a )- polyanions. The potential applications for this synthesis technique are further demonstrated by kilogram-scale reactions and synthesis of other oxychloride SSEs including zirconium-based and tantalum-based analogs. These findings not only provide a new simple, scalable, and energy-efficient synthesis route for oxychloride SSEs but also further promote their application in all-solid-state batteries
