摘要

Due to the high specific capacity,low cost,and environmental friendliness,lithium-sulfur batteries hold great potential to become the mainstay of next-generation energy storage system.Regarding the composition of sulfur/carbon in cathode,flammable organic liquid electrolyte,and lithium metal anode,great concerns about the safety have been raised.Hence solid-electrolyte-based lithium-sulfur batteries,as one alternative route for safe batteries,are highly interested.This review highlights the recent research progress of lithium-sulfur batteries with solid electrolytes.Both sulfide solid electrolytes and oxide solid electrolytes are included.The sulfide solid electrolytes are mainly employed in all-solid-state lithium-sulfur batteries,while the oxide solid electrolytes are applied in hybrid electrolyte for lithium-sulfur batteries.The challenges and perspectives in this field are also featured on the basis of its current progress.
