Highlights Single-layer graphdiyne on MXene (sGDY@MXene) heterostructure was fabricated and integrated into polypropylene separators. directing a LiF-rich solid electrolyte interphase and long-term stability of lithium-metal anode. Instead of direct electron transfer from surface polar groups to fluorinated anions. the adsorbed Li ions on sGDY@MXene act as dynamic bridges collaborativ... https://lecoureures.shop/product-category/ski-de-fond-junior-fixations-classic/
