To mitigate these issues, we report an efficient electrocatalytic interlayer based on a FeCoNiCrMn high-entropy alloy embedded in N-doped carbon nanofibers (HEA@NCNF). The multi-metallic HEA offers abundant active sites, while the N-doped carbon shell not only prevents HEA particle agglomeration and metal leaching, but also establishes a three-dimensional conductive network. Combined X-ray photoelectron spectroscopy and density functional theory calculations elucidate the underlying mechanism: electron modulation from the N-doped carbon layer raises the d-band center of the HEA, thereby strengthening LiPS adsorption and promoting its electrocatalytic conversion. Consequently, the HEA@NCNF interlayer functions as an efficient “trap-and-convert” reactor for LiPSs, which simultaneously suppresses shuttle effects and accelerates redox kinetics. The cells with HEA@NCNF demonstrate exceptional cycling and rate performance, with a capacity decay of only 0.023% per cycle over 1500 cycles at 1C. Remarkably, this superior performance extends to challenging conditions, including high sulfur loading (≥ 7 mg cm<sup>−2</sup>), lean electrolyte, and high-rate operation.

Despite the absence of an insulating spacer between the gold nanopore arrays and silicon nanorods, no luminescence quenching is observed. Furthermore, we employ finite difference time domain simulations to map the electric field distribution and estimate a Purcell factor of 5, which is lower than the experimentally measured luminescence enhancement. This indicates that the observed luminescence enhancement is only partially attributable to the Purcell effect. Importantly, the Purcell effect would not cause a shift in the luminescence peak, whereas a significant peak shift is observed in our experiments. Based on these facts, a novel luminescence mechanism is proposed to complementally account for the remarkable luminescence enhancement observed in our experiments.
