Lithium　metal　batteries　(LMBs)　are　considered　by　most　researchers　as　among　the　most　prospective　nextgeneration　high　energy　density　storage　devices　because　of　high　theoretical　capacity　(3860　mAh　g　-　1)　and　low　reduction　potential　(-3.040　V　compared　to　standard　hydrogen　electrode)　of　Li　metal　anode.　Nevertheless,　the　uncontrollable　dendrite　growth　of　the　Li　metal　anode　during　cycling　hinders　the　commercial　application　of　LMBs.　Herein,　we　put　forward　a　hybrid　protective　layer　containing　LiZn　alloy　and　LiI　at　the　surface　of　the　Li　metal　anode.　Thanks　to　the　＂lithiophilic＂　feature　of　LiZn　alloy　and　LiI　having　a　low　surface　Li+　diffusion　energy　barrier,　the　constructed　homogeneous　hybrid　protective　layer　can　reduce　the　nucleation　barrier　and　facilitate　Li+　rapid　diffusion.　As　a　consequence,　Li　metal　anode　exhibits　a　smooth　plating/stripping　morphology　and　can　suppress　the　dendrite　formation.　Notably,　the　constructed　ZI@Li　||　ZI@Li　symmetrical　cell　realizes　stable　cycling　for　470　h　at　2　mA　cm-2　and　2　mAh　cm-2,　and　LMBs　matched　with　commercial　LiFePO4　cathode　deliver　greatly　enhanced　electrochemical　properties.　This　hybrid　protective　layer　provides　a　feasible　strategy　to　realize　even　plating/　stripping　of　Li　metal,　which　would　promote　the　high　energy　density　LMBs　for　practical　applications.
