In addition to the specific phenomena in solid-state battery systems, the intrinsic large volume change of sulfur originating from the conversion reaction usually can break the physical contact, dramatically reducing the conductive pathways .
Sulfur materials Due to its high theoretical specific capacity (1675 mAh g −1) and low cost, elemental sulfur is considered an ideal active material for lithium-sulfur batteries. In particular, the interface between sulfur and sulfide SSEs shows good chemical compatibility in sulfide-based ASSLSBs.
The incorporation of sulfur into the carbon material can significantly suppress the diffusion of polysulfides into the electrolyte and increase the practical capacity and cycling time of Li-S batteries. 151 This method was one of the first to be developed, but it was found that there are two major problems that prevent its commercial production.
Consequently, sulfur is suitable for the application as an active material in all-solid-state lithium-sulfur cells. In most cases, designing a sulfur composite electrode involves the use of sulfur, a carbon additive, the solid electrolyte itself, and, in some cases, a polymer binder to increase the strength of the electrode. 58, 87, 152
Sulfur utilization in high-mass-loading positive electrodes is crucial for developing practical all-solid-state lithium-sulfur batteries. Here, authors propose a low-density inorganic solid-state electrolyte to improve the sulfur utilization in lab-scale Li-In||S all-solid-state cells.
In general, sulfide electrolytes and sulfide electrodes with the same chemical composition of anions show excellent compatibility with each other. Consequently, sulfur is suitable for the application as an active material in all-solid-state lithium-sulfur cells.
