Due　to　its　exceptionally　high　theoretical　energy　density,　fluorinated　carbon　has　been　recognized　as　a　strong　contender　for　the　cathode　material　in　lithium　primary　batteries　particularly　valued　in　aerospace　and　related　industries.　However,　CFx　cathode　with　high　F/C　ratio,　which　enables　higher　energy　density,　often　suffer　from　inadequate　rate　capability　and　are　unable　to　satisfy　escalating　demand.　Furthermore,　their　intrinsic　low　discharge　voltage　imposes　constraints　on　their　applicability.　In　this　study,　a　novel　and　high　F/C　ratio　fluorinated　carbon　nanomaterials　(FNC)　enriched　with　semi-ionic　C-F　bonds　is　synthesized　at　a　lower　fluorination　temperature,　using　aggregated　nanocarbon　as　the　precursor.　The　increased　presence　semi-ionic　C-F　bonds　of　the　FNC　enhances　conductivity,　thereby　ameliorating　ohmic　polarization　effects　during　initial　discharge.　In　addition,　the　spherical　shape　and　aggregated　configuration　of　FNC　facilitate　the　diffusion　of　Li+　to　abundant　active　sites　through　continuous　paths.　Consequently,　the　FNC　exhibits　high　discharge　voltage　of　3.15　V　at　0.01C　and　superior　rate　capability　in　lithium　primary　batteries.　At　a　high　rate　of　20C,　power　density　of　33,694　W　kg(-1)　and　energy　density　of　1,250　Wh　kg(-1)　are　achieved.　Moreover,　FNC　also　demonstrates　notable　electrochemical　performance　in　sodium/potassium-CFx　primary　batteries.　This　new-type　alkali-metal/CFx　primary　batteries　exhibit　outstanding　rate　capability,　rendering　them　with　vast　potential　in　high-power　applications.
