The use of sulfide solid electrolytes has considerably promoted the development of all-solid-state lithium batteries because of advantages such as a high ionic conductivity, formability, and good interface compatibility with electrodes.
The successful utilization of innovative sulfide-based solid-state batteries in energy storage hinges on developing scalable technologies and machinery for upscaling their production.
In this study, the conventional production of lithium-ion batteries is reconsidered, and the feasibility of seamlessly integrating sulfide-based solid-state batteries into the existing process chains is discussed. Scalable technologies and key challenges along the process chain of sulfide-based solid-state batteries are accordingly addressed.
Traditional preparation methods for sulfide solid electrolytes include solid-state sintering, high-energy ball milling, and liquid-phase methods (Fig. 1) [17, 18]. Solid-state sintering involves mixing raw materials at a specific stoichiometric ratio to obtain precursor sulfide solid electrolytes.
To overcome these difficulties, inert coatings, replacing sulfide solid electrolytes with halide solid electrolytes, and replacing frequently used transitional metal oxide cathode materials with other materials that are better suited for sulfide solid electrolytes to modify the composite cathode have been explored.
In the aforementioned applications of liquid-phase methods in all-solid-state lithium batteries, whether in the encapsulation and composite of electrolytes with cathodes, doping of electrolyte elements, or fabrication of electrolyte thin films, liquid-phase methods have demonstrated robust capabilities.
