Abstract
- Lithium metal has been treated as one of the most promising anode materials for next-generation rechargeable batteries due to its extremely high theoretical capacity. However, its practical application is hindered by inhomogeneous lithium deposition and uncontrolled dendrite growth. In this work, we prepared a three-dimensional nickel foam (NF)-based current collector with a lithiophilic interface layer through facile hydrothermal and coating methods. The lithiophilic Ni <subscript>3</subscript> S <subscript>2</subscript> array synthesized via a hydrothermal method has been demonstrated to facilitate the nucleation of Li <superscript>+</superscript> . Moreover, it has been observed that the outer coating comprising LPP effectively enhances the inward diffusion of Li <superscript>+</superscript> . Additionally, this interface layer can serve as an isolating barrier between the electrodes and the electrolyte. The prepared LPP-Ni <subscript>3</subscript> S <subscript>2</subscript> @Ni shows significant reversibility both in symmetric cells (1200 h, 1 mA cm <superscript>-2</superscript> ) and half-cells (CE: 99.60%, 500 cycles, 1 mA cm <superscript>-2</superscript> ) with low interfacial resistance (35 Ω). Full cells with LiFePO <subscript>4</subscript> as a cathode also exhibit promising electrochemical performance with over 76.78% capacity retention over 200 cycles at 1 C.
