Manufacturing High-Energy-Density Sulfidic Solid-State Batteries

All-solid-state batteries (ASSBs) using sulfide solid electrolytes with high room-temperature ionic conductivity are expected as promising next-generation batteries, which might solve the safety issues and enable utilization of lithium metal anode to further increase energy density cells. Most researchers in academic community currently focus on developing novel electrolytes, clarifying interface between electrodes mechanism dendrite growth ASSB. However, there is a lacking technical route analysis about commercialization ASSBs based electrolytes. This review mainly introduces specific preparation methods various parts sulfide-based ASSBs, including electrolyte particles, composite membranes, cathodes anodes, analyzes advantages disadvantages these methods. In addition, several schemes ASSB assembly also introduced. Finally, perspective large-scale production provided, accelerate ASSBs.
