Abstract：

The　exceptional　energy　density　and　stability　of　fluorinated　carbon　(CFx)　cathode　materials　have　shone　brightly　in　the　field　of　Li　primary　batteries.　However,　the　development　of　Li/CFx　secondary　batteries　has　hit　a　bottleneck　due　to　the　high　dissociation　energy　and　band　gap　energy　of　LiF.　Herein,　a　fluorinated　biomass　hard　carbon　(FTS/Ni),　with　Ni　functional　layer　rich　in　catalytic　active　sites　deposited　on　CFx　surface　via　magnetron　sputtering,　is　synthesized,　showing　high　reversibility　of　lithium　ions　storage.　FTS/Ni　cathode　with　1.5　wt%　Ni　content　exhibits　high　capacity　of　250　mAh　g−1　within　voltage　window　of　1.5–5.0　V.　Density　functional　theory　(DFT)　calculations　confirm　that　Ni　catalyst　could　reduce　the　dissociation　energy　of　LiF,　accelerating　the　conversion　kinetics　of　LiF,　thereby　enhancing　the　secondary　electrochemical　performance　of　Li/CFx　batteries.　This　work　demonstrates　that　the　reversibility　of　LiF　within　the　voltage　window　of　1.5–5.0　V　can　be　achieved　through　Ni　catalytic　action,　pointing　out　a　promising　direction　for　the　secondary　rechargeability　of　Li/CFx　batteries.　©　2025　Elsevier　B.V.
