Metal　skeletons,　such　as　Nickel　Foam　(NF)　has　attracted　worldwide　interests　as　stable　host　for　lithium　metal　anode　because　of　its　high　stability,　large　specific　surface　area　and　high　conductivity.　However,　most　metal　skeletons　have　lithophobic　surface　and　uneven　current　distribution　that　result　in　sporadic　lithium　nucleation　and　uncontrolled　dendrites　growth.　Herein,　we　describe　a　sequential　immersing　strategy　to　generate　interwoven　Nickel(II)-dimethylglyoxime　(Ni-DMG)　nanowires　at　NF　to　obtain　composite　skeleton　(NDNF),　which　can　be　used　as　an　stable　host　for　Li　metal　storage.　The　Ni-DMG　has　proved　effective　to　realize　uniform　lithium　nucleation　and　dendrite-free　lithium　deposition.　Combing　with　the　three　dimensional　(3D)　hierarchical　porous　structure,　the　composite　host　shows　a　significantly　improved　coulombic　efficiency　(CE)　than　pristine　commercial　nickel　foam.　Moreover,　the　corresponding　Li　parallel　to　Li　symmetrical　cells　can　run　more　than　700　h　with　low　voltage　hysteresis　22　mV　at　1.0　mA/cm(2),　and　Li@NDNF　parallel　to　LiFePO　4　full-cell　exhibits　a　high　capacity　retention　of　82.03%　at　1.0　C　during　630　cycles.　These　results　proved　the　effectiveness　of　metal-organic　complexes　in　governing　Li　metal　growth　and　can　be　employed　as　a　new　strategy　for　dendrite-free　Li　metal　anode　and　safe　Li　metal　batteries　(LMBs).　(c)　2022　Published　by　Elsevier　B.V.　on　behalf　of　Chinese　Chemical　Society　and　Institute　of　Materia　Medica,　Chinese　Academy　of　Medical　Sciences.
