Although the great demand for high-energy-density batteries has inspired the renewed interest of rechargeable lithium metal batteries that use metallic lithium as the anode, short lifespan and serious safety risks caused by the substantial volume change of the Li electrode during plating/stripping and the uncontrollable growth of Li dendrites are two main issues of Li metal anode. In this study, a new 3D Cu current collector with a pore structure of vertical micro-channels coated with a lithiophilic Li-Sb interphase is prepared via a facile synthesis procedure. The introduced lithiophilic interphase can dramatically reduce the Li nucleation barrier to inhibit the formation of Li dendrites. The vertical micro-channels pore structure can effectively lower the local current density to regulate a smooth Li deposition. Consequently, the symmetrical cells with the hybrid architecture substrate demonstrates an ultra-long lifespan over 2000 h at 12 mA cm⁻² for 12 mAh cm⁻². Full cells made of such a 3D copper supported Li anode coupled with a LiFePO₄ cathode with a similar architeture can achieve a remarkable retention of 91.23% at a high areal capacity (~ 6 mAh cm⁻²) over 150 cycles under a harsh condition (low N/P capacity ratio of 1.5).

尽管对高能量密度电池的巨大需求激发了人们对使用金属锂作为负极的可再充电锂金属电池的新兴趣，但是由于锂电极在电镀/剥皮和剥离过程中体积的巨大变化，使用寿命短且存在严重的安全隐患锂枝晶的不可控生长是锂金属阳极的两个主要问题。在这项研究中，通过一种简便的合成方法，制备了一种新的3D Cu集电器，该集电器具有垂直微通道的孔结构，该孔具有涂有亲硫的Li-Sb相的涂层。引入的亲硫中间相可以显着降低Li成核屏障，从而抑制Li树枝状晶体的形成。垂直的微通道孔结构可以有效降低局部电流密度，以调节平滑的锂沉积。所以，^-2为12毫安厘米^-2。由这种3D铜负载的Li阳极与类似结构的LiFePO ₄阴极结合制成的全电池在苛刻的条件下（150 ^°C）在150循环的高面积容量（〜6 mAh cm ^-2）下可实现91.23％的显着保留率。N / P容量比低（1.5）。
