Customer ServiceAs a promising kind of solid electrolytes, sulfide-based solid electrolytes are desirable for the solid-state sodium batteries because of their relatively high sodium ionic conductivity, low grain boundary resistance, good plasticity, and moderate synthesis conditions, compared with oxide electrolytes , , , , , , , .
Therefore, for sulfide-based solid-state sodium batteries, the increase in energy density can be divided into two directions: to optimize the composition and interface to improve the rate performance of sulfur and transition metal sulfides, and to introduce high-voltage cathode materials. Fig. 6.
Constructing anode-free sulfide-based solid-state sodium batteries. If the energy density of sulfide-based solid-state sodium batteries is expected to be close to that of lithium-ion batteries, it is necessary to construct an anode-free system.
In recent years, solid-state sodium batteries have attracted extensive attention because of their improved safety, considerable energy density, and low cost. Nevertheless, high-performance solid-state electrolyte and compatible interface are still absent and need to be further developed for constructing solid-state sodium batteries.
Meanwhile, large-scale production of high-performance solid-state electrolyte via a facile and scalable method with low cost is also necessary. Sodium batteries are considered as promising candidates for large-scale energy-storage systems owing to the abundant and low-cost sodium resources.
Therefore, the performance of solid-state sodium batteries is mainly dominated by the electrolyte/electrode interfaces. In this regard, sulfide-based and polymer SSE would be the promising alternatives for practical applications because good interfacial contact between them and electrodes could be achieved without hot pressing.
