Abstract：

The　electrochemical　performance　of　Li　metal　anode　is　closely　bound　up　with　the　interphase　between　Li　and　lithium-loaded　skeleton　as　well　as　solid　electrolyte　interphase　(SEI)　on　Li　surface.　Herein,　for　the　first　time,　we　propose　a　novel　liquid-source　CHBr2F　plasma　technology　to　simultaneously　construct　dual　bromine-fluorine-enriched　interphases:　NiBr2-NiF2　interphase　on　sponge　Ni　(SN)　skeleton　and　LiBr-LiF-enriched　SEI　on　Li　anode,　respectively.　Based　on　density　functional　theory　(DFT)　calculations　and　COMSOL　multiphysics　simulation　results,　SN　skeleton　with　NiBr2-NiF2　interphase　can　effectively　decrease　the　local　current　density　with　good　lithiophilicity.　And　the　LiBr-LiF-enriched　SEI　on　Li　surface　can　function　to　block　electron　tunneling　and　hinder　side　electrochemical　reduction　of　electrolyte　components,　thus　suppressing　the　growth　of　dendrite　and　facilitating　the　homogeneous　transportation　of　lithium　ions.　Consequently,　the　Li/SN　electrodes　with　modified　interphases　show　remarkable　stability　with　a　low　overpotential　of　22.6　mV　over　1800　h　at　1　mA　cm–2/1　mAh　cm–2　and　an　exceptional　average　Coulombic　efficiency　of　99.6%.　When　coupled　with　LiNi0.8Co0.1Mn0.1O2　(NCM811)　cathode,　the　full　cells　deliver　improved　cycling　stability　with　a　capacity　retention　of　79.5%　even　after　350　cycles　at　0.5　C.　This　study　provides　a　facile　and　new　plasma　method　for　the　construction　of　advanced　Li　anodes　for　energy　storage.　©　2023
