Abstract：

The　lithium　metal　anode　has　been　considered　the　most　promising　anode　in　rechargeable　batteries　to　meet　the　ever-increasing　requirements　of　high　energy　density.　Herein,　a　3D　porous　lithiophilic-lithiophobic-lithiophilic　dual-gradient　Cu-Au-ZnO-PAN-ZnO　(CAZPZ)　current　collector　is　fabricated　to　suppress　Li　dendrite　growth.　The　lithiophilic　Au　and　ZnO　at　the　bottom　are　favorable　for　homogeneous　Li　nucleation,　the　ZnO-PAN-ZnO　skeleton　provides　plenty　of　space　to　accommodate　deposited　Li　and　the　lithiated　ZnO　(Li2O/LixZn)　layer　can　act　as　an　artificial　SEI　to　regulate　the　well-distributed　Li+　flux.　As　a　result,　long-term　stabilization　for　1200　h　at　0.5　mA　cm-2　and　a　low　overpotential　of　22　mV　at　3　mA　cm-2　are　achieved　in　symmetric　cells.　Moreover,　the　CAZPZ-Li　hybrid　anode　exhibits　superb　electrochemical　properties　when　matched　with　a　LiFePO4　(LFP)　cathode.　The　CAZPZ-LiLFP　full　cells　exhibit　excellent　stabilization　for　1000　cycles　at　5C　with　a　high　capacity　retention　of　97.3%.　The　lithiophilic-lithiophobic-lithiophilic　dual-gradient　design　of　the　3D　porous　current　collector　for　the　Li　metal　anode　can　be　a　very　promising　strategy　to　enable　the　practical　application　of　Li　metal　batteries.　©　2019　The　Royal　Society　of　Chemistry.
