Lithium/carbon　fluoride　(Li/CFx)　batteries　have　been　widely　researched　due　to　their　high　theoretical　specific　energy.　To　create　a　high-performance　electrode,　the　fluorinated　hard　carbon　(FHC)　is　prepared　by　direct　gas-phase　fluorination.　It　has　a　high　F/C　ratio　of　0.95　based　on　the　gravimetric　method.　Selecting　hard　carbon　(HC)　with　a　high　surface　area　as　the　carbon　source　allows　for　FHC　to　achieve　suitable　interlayer　spacing　and　specific　surface　area,　as　well　as　abundant　pore　structures　to　facilitate　rapid　lithium　ion　transportation.　Additionally,　a　composite　of　graphene　and　carbon　nanotubes　(CNTs)　is　coated　on　the　surface　of　FHC,　enhancing　electron　transport　speed.　The　resulting　FHC&C　exhibits　a　very　high　energy　density　of　1256　Wh　kg−1　and　an　excellent　power　density　of　72,929　W　kg−1　at　a　high　rate　of　40　C.　Moreover,　compared　to　commercial　CFx,　FHC&C　exhibits　higher　energy　and　power　densities,　thus　presenting　a　promising　practical　application　prospect.　©　2023　by　the　authors.
