| Abstract Scope |
Lithium-sulfur (Li-S) batteries have the potential to deliver higher energy at lower cost compared to state-of-the-art Li-ion batteries. Greatest obstacles for deployment of Li-S batteries lie in polysulfide dissolution and high Electrolyte/sulfur ratio required for long term cycling. In all-solid-state Li-S batteries (ASSLiS), S conversion undergoes the solid-state route therefore excludes the problems of polysulfide dissolution and high E/S ratio. Sulfide-based solid state electrolytes (SSE) are most suitable for ASSLiS.Due to the insulating nature of S particles, short diffusion length is needed to realize high S utilization, which requires nanosized SSE particle. The other significant obstacle of ASSLiS is lack of SSE that support stable Li metal cycling at relevant current density and cycling depth. In this talk, we'll present our progress on the sulfide-based solid electrolytes for ASSLiS including synthesis of nanosized SSE and the highly conductive SSE with low-impedance interface with Li metal anode. |
