Solid-state　electrolytes　(SSEs)　with　flame　retardancy　and　good　adaptability　to　lithium-metal　anodes　can　have　great　potential　in　enabling　high　safety　and　high　energy　density　lithium-metal　batteries.　In　addition　to　optimize　the　composition/structure　of　current　three　main　types　of　SSEs　including　inorganic　SSEs,　polymeric　SSEs,　and　inorganic/polymer　composite　SSEs,　massive　efforts　are　under　way　to　seek　for　new　SSE　formulations.　Recently,　metal-organic　frameworks　(MOFs),　a　type　of　crystalline　inorganic-organic　materials　with　the　structural　features　of　rich　porous,　ordered　channels,　tunable　functionality,　are　emerging　as　a　research　hotspot　in　the　field　of　SSEs,　which　have　attracted　tremendous　efforts.　Based　on　the　latest　investigations,　in　this　paper,　a　systematic　overview　of　the　recent　development　in　MOFs-based　SSEs　(MSSEs)　for　lithium-metal　batteries　is　presented.　Classification　and　compositions,　development　history,　fabrication　approaches,　and　recent　progress　of　five　main　types　of　MSSEs　are　comprehensively　reviewed,　and　the　roles　of　MOFs　in　MSSEs　including　ionic　conductors,　ionic　transport　carriers,　and　added　fillers　are　highlighted.　Moreover,　the　main　challenges　are　analyzed　and　the　perspectives　of　MSSEs　are　also　presented　for　their　future　research　and　development.　This　review　not　only　contributes　to　the　study　of　new　systems　of　solid-state　electrolytes,　but　also　for　further　development　of　electrified　transportation.
