Lithium　(Li)　metal　is　a　promising　candidate　for　next-generation　anode　materials　with　high　energy　densities.　However,　Li　dissolution/deposition　processes　are　limited　at　the　upper　surface　in　contact　with　the　electrolyte,　which　brings　a　locally　high　current　density　and　then　results　in　dendritic　Li　growth.　This　restraint　of　the　local　surface　reaction　during　cycling　has　not　been　solved　by　commonly　used　modification　strategies.　In　this　study,　a　three-dimensional　(3D)　Li+　conductive　skeleton　is　activated　from　atomic　layer　deposition　(ALD)　coating　Li3PO4　(LPO)　on　the　surface　of　the　Ni　foam　(LPNF).　Then,　the　skeleton　is　efficiently　constructed　in　the　Li　metal　anode　by　the　lower-temperature　Li　infusion.　Ionic　conductor　LPO　layers　and　electronic　conductor　Ni　fibers　supply　charge　transport　channels　between　the　electrolyte　and　the　internal　Li.　The　mixed　conductive　network　realizes　holistic　charge　transfer,　which　is　proved　by　in　situ　scanning　electron　microscopy　experiments.　In　virtue　of　dispersive　dissolution/deposition　and　optimized　electrochemical　kinetics　brought　by　a　Li+　conductive　network,　the　composited　Li　electrode　presents　an　excellent　symmetric　battery　cycling　stability　(over　1200　h)　and　enhanced　rate　performances　(stable　cycling　even　at　10.0　mA　cm-2).　When　matching　with　a　LiCoO2　(LCO)　cathode,　LCO||Li@LPNF　full　batteries　exhibit　a　capacity　retention　of　80.8%　over　250　cycles.　During　cycling,　there　was　no　evidence　of　dendrite　growth　and　the　remaining　Li　in　the　composited　anode　showed　a　smooth,　compact,　and　well-combined　condition　with　LPNF.　Through　constructing　a　3D　Li+　conductive　network,　the　composited　Li　metal　anode　breaks　through　the　limit　of　the　local　surface　reaction;　this　work　proposes　a　novel　insight　of　realizing　holistic　charging/discharging　for　the　dendrite-free　Li　metal　anode.
