Li metal is the most ideal anode material for next-generation high energy lithium-ion batteries.The uncontrollable growth of Li dendrites,however,hinders its practical application.Herein,we propose the adoption of Zn nanoparticles uniformly embedded in N-doped carbon polyhedra homogeneously built on carbon cloth (Zn@NC@CC) to prevent the formation of Li dendrites.Based on theoretical calcu-lation and experimental observation,lithiophilic Zn nanoparticles and N-doping inside of the as-synthesized Zn@NC play a synergistic role in enhancing the adsorption capacity with Li,thus resulting in uniform Li deposition and complete suppression of Li dendrites.Moreover,the porous N-doped carbon polyhedras uniformly distributed on carbon cloth effectively relieves the volume change of Li upon repeated Li stripping/plating process,which contributes to preserving the structural integrity of the whole electrode and hence enhancing its long-term cycling stability.Benefiting from these synergistic effects,the Li-Zn@NC@CC electrode delivers a prolonged lifespan of over 1200 h at 1 mAcm-2 with an areal capacity of 1 mA hcm-2 in symmetric cells and high Coulombic efficiencies of 95.4％ under an ultra-high capacity of 12 mA hcm-2.Remarkably,H-Zn@NC@CC//LiFePO4 full cells deliver a high reversible capacity of 110.2 mA h g-1 at 1C over 200 cycles.
