The commercial development of lithium ion batteries (LIBs) have been hampered from the uncontrollable growth of Li dendrites and low coulombic efficiency (CE). In this respect, the exploration of advanced host materials to regulate the behavior of Li plating/stripping is an effective strategy to resolve those issues. In this work, we report the modified Ni foam by Au nanoparticles decorated reduced graphene oxide (rGO) as effective Li host (denoted as Au@rGONi). Thus-prepared Li host enabled a stable CE as high as 96.5% after 100 cycles at a current density of 1 mA cm⁻² with a capacity of 1 mAh cm⁻². The according symmetric cell delivered a long-term lifespan of 1000 h without obvious voltage fluctuation under 0.5 mA cm⁻²/1 mAh cm⁻². More encouragingly, a full LIB based on the Au@rGONi-300 anode and LiFeO₄ cathode demonstrated excellent discharge-charge cycling behavior with a high capacity of 130.5 mAh g⁻¹ after 140 cycles at 0.2C. This work presents the feasibility to develop stable lithium metal anodes by surface modification of commercial Ni foam with lithiophilic materials.

锂离子电池（LIB）的商业开发受到Li树枝状晶体不可控制的增长和低库仑效率（CE）的阻碍。在这方面，探索先进的主体材料来调节锂电镀/剥离的行为是解决这些问题的有效策略。在这项工作中，我们报告了金纳米粒子修饰的还原Ni泡沫修饰的还原氧化石墨烯（rGO）作为有效的Li主体（表示为Au @ rGONi）。由此制备的锂主机在1毫安cm 2的电流密度使能稳定的CE高达96.5％100次循环后^-2以1毫安厘米的容量^-2。在0.5 mA cm ^-2 / 1 mAh cm ^-2下，上述对称电池可提供1000 h的长期使用寿命，而不会出现明显的电压波动。更令人鼓舞的是，基于Au @ rGONi-300阳极和LiFeO ₄阴极的完整LIB在0.2C循环140次后表现出出色的放电-充电循环性能，高容量为130.5 mAh g ^-1。这项工作提出了通过使用亲硫性材料对商用镍泡沫进行表面改性来开发稳定的锂金属阳极的可行性。
