Enhancing Li-S Battery Performance by Harnessing the Power of Single Atoms on 2d Borophene

Опубликована: Янв. 1, 2025

Li-S batteries are potentially interesting alternatives for green energy applications due to their high density and low cost. Nonetheless, present practical application falls short of theoretical predictions, despite efforts address volumetric expansion enhance electrical conductance through porous sulfur-hosting scaffolds. The performance is mainly restricted by the poor electrochemical reaction kinetics lithium polysulfides (LiPS), which convert into sulfide (Li2S) elemental sulfur (S) during charge-discharge cycles. Single-atom catalysts (SACs) offer novel opportunities addressing complex challenges effective in atomic-resolution characterization intermediates as well precise atomic-level engineering. Inspired single-atom catalysis approach, we designed an innovative electrocatalyst including FeN4 active sites anchored 2D borophene nanosheets. significant electronic coupling between Fe 3d S 2p orbitals promotes charge transfer improves redox dynamics polysulfide intermediates. Moreover, unique properties borophene, its mass density, superior conductivity, rapid Li-ion transport, robust binding with polysulfides, render it a promising choice battery materials. synergistic effect adsorption improved kinetics, enabled configuration three-dimensional architecture FeN4/borophene (Fe@BNS), results outstanding batteries. fabricated cells exhibit exceptional long-term cycle life (1180 mAh g−1 at 1 C 1000 cycles) high-rate (790.3 C) loading 6.5 mg cm−2.
