Recent progress of sulfide electrolytes for all-solid-state lithium batteries

Solid electrolytes are recognized as being pivotal to next-generation energy storage technologies. Sulfide with high ionic conductivity represent some of the most promising materials realize high-energy-density all-solid-state lithium batteries. Due their soft nature, sulfides possess good wettability against Li metal and preparation process is relatively effortless. High cell-level sulfide-based batteries have gradually been realized in recent years. However, there still several disadvantages that sulfide need overcome, including sensitivity humid air instability electrodes. Herein, progress for electrolytes, particular attention given electrolyte synthesis mechanisms, electrochemical chemical stability, interphase stabilization density, presented.
