Plasma-Constructed Nickel Fluoride Lithiophilic Interlayer for High-Performance Lithium Metal Anodes
A three-dimensional host architecture has emerged as a promising strategy for developing high-energy lithium metal anodes, where the lithiophilic characteristics and interfacial compatibility of the host material play pivotal roles in determining the electrochemical performance. In this work, we demonstrate an innovative gas plasma-assisted technique for in situ synthesis of NiF2 coatings on nickel fiber current collectors. The three-dimensional interconnected NiF2-modified Ni fiber network not only provides efficient electron transport pathways but also enables homogeneous lithium-ion flux distribution, synergistically reducing local current density and alleviating volume changes during cycling. The NiF2-modified Ni fiber/lithium metal anode (Li/FN) achieves a low overpotential of 16.7 mV for 2600 h at a current density of 1 mA cm–2 with a high average Coulombic efficiency of 99.1%, showing a marked improvement over its unmodified counterpart. When paired with LiN0.8Co0.1Mn0.1O2 (NCM811) cathodes, the assembled full cells exhibit a capacity retention rate of 85.2% after 100 cycles at 0.5 C. This plasma-enabled surface engineering approach presents a scalable and efficient pathway for fabricating high-performance lithium metal anodes, offering new insights into interface optimization strategies for next-generation battery systems.
