3D metallic frameworks for lithium metal anodes (LMA) have attracted wide interests due to large specific surface area and high stability. However, their poor lithiophilic surface still suffers non-uniform lithium nucleation and dendrite growth. The construction of oxide layers on the metallic surfaces have been widely reported to effectively improve the surface lithiophilicity. In comparison, metallic nitrides with both strong affinity to lithium and high conductivity have been seldom studied. Herein, a novel and simple strategy has been adopted to build a lithiophilic and compact nitride layer on the nickel foam by an eco-friendly plasma process. The nitride decorated nickel foams (PNNF) not only show higher specific surface area, but also uniform lithium deposition by the formation of lithiophilic and high ion conductive Li₃N. In turn, the PNNF in a symmetric cell exhibited low voltage hysteresis 13, 18 and 39 mV at 1, 2 and 5 mA/cm² respectively for over 400 cycles. In addition, the fabricated full-cell paired with LiFePO₄ cathode displayed a high reversible capacity 167.1 mAh/g after 300 cycles and stable cycling performance, indicating a preeminent potential for practical application. Moreover, this work provides a new strategy for the use of metallic nitrides as lithiophilic layer for LMA.

由于大比表面积和高稳定性，用于锂金属阳极（LMA）的3D金属框架引起了广泛的兴趣。然而，它们不良的亲硫表面仍然遭受不均匀的锂成核和枝晶生长。已经广泛报道了在金属表面上构造氧化物层以有效改善表面的亲锂性。相比之下，很少研究对锂具有强亲和力和高电导率的金属氮化物。本文中，已采用新颖且简单的策略通过生态友好的等离子体工艺在镍泡沫上建立亲硫的致密氮化物层。氮化物装饰的镍泡沫（PNNF）不仅显示出更高的比表面积，而且还通过形成亲硫性和高离子导电性的Li形成了均匀的锂沉积₃ N.反过来，以对称的小区中的PNNF表现出低的电压滞后13，18和39毫伏为1，2和5毫安/平方厘米²分别为超过400个循环。此外，与LiFePO ₄阴极配对的已制成全电池在300次循环后显示出167.1 mAh / g的高可逆容量，并具有稳定的循环性能，这表明其在实际应用中具有巨大的潜力。此外，这项工作为使用金属氮化物作为LMA的亲硫层提供了新的策略。
