Lithium　metal　anode　is　considered　one　of　the　most　promising　anode　materials　for　lithium　rechargeable　batteries　due　to　its　highest　theoretical　specific　capacity　and　lowest　anode　potential.　However,　dendritic　growth　during　Li　planting　leads　a　safety　concern　and　hinders　the　application　of　lithium　(Li)　metal　batteries.　Herein,　unique　3D　nanoporous/macroporous　structure　conductive　Cu　was　designed　and　used　as　the　current　collector　for　Li　planting/stripping　to　regulate　metal　Li　deposition　and　inhibit　the　growth　of　lithium　dendrite.　The　nanoporous/macroporous　Cu　current　collector　can　effectively　reduce　the　local　current　density　and　guide　the　metallic　Li　nucleation,　leading　Li　to　deposit　uniformly　on　its　surface.　As　a　result,　the　modified　Li@　nanoporous/macroporous　Cu　current　collector　composite　anode　possesses　a　dendrite-free　morphology　and　an　enhanced　cycling　stability　with　a　high　average　Coulombic　efficiency　of　98%　for　400　h.　When　matching　the　LiFePO4　cathode,　the　LiFePO4　and　Li@porous　Cu　current　collector　anode　resultant　full　cell　exhibits　stable　cycling　performance.
