Lithium metal establishes a promising anode, but it suffers from dendrite growth. Constructing a current collector with stable artificial solid electrolyte interphase (SEI) and lithiophilic matrix is highly considered for achieving uniform lithium (Li) deposition. In this work, lithiophilic silver nanoparticles with polydopamine (Ag@PDA) were synthesized successfully and coated on the copper (Cu) current collector to use as a nucleation seed to improve the lithium nucleation. More importantly, graphene oxide (GO) was effectively coated on the top of Ag@PDA to act as artificial SEI to buffer the Li-ion distribution in anode free lithium metal batteries (AFLMBs). Thus, the synergistic effect of the modified electrodes displays a uniform Li metal deposition and dendrite free morphology during repeated cycling. Accordingly, the Cu|Ag@PDA//Li, and Cu|Ag@PDA-GO//Li cells demonstrate relatively uniform lithium nuclei, lower nucleation overpotential, and higher CE compared to the uncoated electrode. Besides, the Cu|Ag@PDA-GO//NMC full cell owns higher average Coulombic efficiency (~ 98.6%) and higher capacity retention (~ 55.7%) after 60 cycles within 5% fluoroethylene carbonate (FEC) in the carbonate-based electrolyte at 0.5 mA cm⁻². While, the bare copper only achieves, 94.4% and 4.3% average Coulombic efficiency and capacity retention, respectively. Therefore, a lithiophilic matrix integrated with an artificial SEI coating on the Cu substrate offers a feasible way for the inhibition of lithium dendrite and electrolyte decomposition in the anode free lithium metal batteries (AFLMBs).

锂金属建立了有希望的阳极，但它会遭受树枝状晶体的生长。为了实现均匀的锂（Li）沉积，高度考虑构建具有稳定的人造固体电解质中间相（SEI）和亲硫基质的集电器。在这项工作中，成功合成了具有聚多巴胺（Ag @ PDA）的亲锂银纳米颗粒，并将其涂覆在铜（Cu）集电器上，用作成核晶种以改善锂的成核作用。更重要的是，在Ag @ PDA的顶部有效地涂覆了氧化石墨烯（GO），用作人造SEI，以缓冲锂离子在无阳极锂金属​​电池（AFLMBs）中的分布。因此，在重复循环期间，修饰电极的协同作用显示出均匀的锂金属沉积和无枝晶形态。因此，Cu | Ag @ PDA // Li 与未涂覆的电极相比，Cu | Ag @ PDA-GO // Li电池表现出相对均匀的锂核，较低的成核超电势和较高的CE。此外，在碳酸盐基的5％氟代碳酸亚乙酯（FEC）中经过60个循环后，Cu | Ag @ PDA-GO // NMC全电池具有更高的平均库仑效率（〜98.6％）和更高的容量保持率（〜55.7％）。电解质在0.5 mA厘米⁻²。而仅裸铜分别达到了94.4％和4.3％的平均库仑效率和容量保持率。因此，在铜基板上集成了人工SEI涂层的亲硫基质为抑制无阳极锂金属​​电池（AFLMBs）中的锂枝晶和电解质分解提供了一种可行的方法。
