Lithium metal has been regarded as the most ideal choice to be anode for rechargeable lithium batteries. However, lithium dendrites growth and unstable interface between lithium and electrolyte result in security risk and poor cyclic performance, hindering practical applications of lithium anode. By analyzing kinetic parameters and the morphology of initial lithium deposition, we find that In₃Li₁₃ substrate exhibits excellent lithiophilic nature with extremely small nucleation barrier of lithium. Thus, an integrated Li-rich Li-In anode with lithiophilic In₃Li₁₃ framework was designed and prepared by a facile one-step vacuum evaporation approach. The framework reduces the local current density and accommodates lithium in the interior space. Most importantly, the lithiophilic In₃Li₁₃ can guide uniform Li nucleation. Via the synergy of lithiophilic framework in structure and interface, the designed integrated Li-In anode exhibits excellent electrochemical performance. Symmetric cells with the Li-In anode stably cycle for over 230 hours, about four times the lifespan of the cell with the pure lithium anode. In the full cells with LiFePO₄ cathode, the capacity retention is improved from 83.6% to 97.7% after 160 cycles with the Li-In anode. These attempts deepened the understanding of Li nucleation on lithiophilic substrate and provide new insight for designing high-performance lithium anode.

金属锂一直被认为是可充电锂电池阳极的最理想选择。然而，锂树枝状晶体的生长以及锂与电解质之间的不稳定界面导致安全风险和差的循环性能，从而阻碍了锂阳极的实际应用。通过分析动力学参数和初始锂沉积的形态，我们发现In ₃ Li ₁₃衬底表现出优异的亲锂性，并且锂的成核势垒非常小。因此，具有富硫的In ₃ Li ₁₃的集成的富锂Li-In阳极通过简便的一步真空蒸发方法设计和制备了该框架。该框架降低了局部电流密度，并在内部空间中容纳了锂。最重要的是，亲硫的In ₃ Li ₁₃可以引导均匀的Li成核。通过亲硫骨架在结构和界面上的协同作用，设计的集成锂铟阳极具有出色的电化学性能。带有Li-In阳极的对称电池可稳定循环230个小时以上，约为纯锂阳​​极电池寿命的四倍。在充满LiFePO ₄的完整电池中阴极，使用锂铟阳极160次循环后，容量保持率从83.6％提高到97.7％。这些尝试加深了对Lithiophilic衬底上Li成核的理解，并为设计高性能锂阳极提供了新的见识。
