High performance of lithium-sulfur batteries have been dragged down by their shuttling behavior which is complicated multiphase transition-based 16-electron redox reactions of the S8/Li2 *** this article,the triple-phase interfaces of graphene-like carbon clusters on antimony trisulfide(C-Sb_(2)S_(3))nanowires are tailored to design a multifunctional polysulfide host which can inhibit migration of polysulfides and accelerate conversion kinetics of redox electrochemical *** from the triple-interface design of polysulfides/Sb_(2)S_(3)/carbon clusters,the C-Sb_(2)S_(3) electrode not only anchors polysulfide migration by the synergistic effect of Sb,S,and C atoms as interfacial active sites,but also the graphene-like carbon clusters shorten the diffusion paths to further favor redox electron/ion transport through the liquid(electrolyte/polysulfide)and solid(Li2 S/S8,carbon clusters,and Sb_(2)S_(3))-based ***,these Li_(2)S_(6)-based C-Sb_(2)S_(3) cells possess high sulfur loading,excellent cycling stability,impressive specific capacity,and great rate *** work of interfacial engineering reveals insight for powering reaction kinetics in the complicated multistep catalysis reaction with multiphase evolution-based chargetransfer/non-transfer processes.

The point-to-point contact mechanism in all-solid-state Li-S batteries(ASSLSBs)is not as efficient as a liquid electrolyte which has superior mobility in the electrode,resulting in a slower reaction kinetics and inadequate ionic/electronic conduction network between the S(or Li_(2)S),conductive carbon,and solid-state electrolytes(SSEs)for achieving a swift(dis)charge ***,a series of hybrid ionic/electronic conduction triple-phase interfaces with transition metal and nitrogen co-doping were *** graphitic ordered mesoporous carbon frameworks(TM-N-OMCs;TM=Fe,Co,Ni,and Cu)serve as hosts for Li_(2)S and Li_(6)PS_(5)Cl(LPSC)and provide abundant reaction sites on the triple *** from both experimental and computational research display that the combination of Cu-N co-dopants can promote the Li-ion diffusion for rapid transformation of Li_(2)S with adequate ionic(6.73×10^(−4)S·cm^(−1))/electronic conductivities(1.77×10^(−2)S·cm^(−1))at 25℃.The as-acquired Li_(2)S/Cu-N-OMC/LPSC electrode exhibits a high reversible capacity(1147.7 mAh·g^(−1))at 0.1 C,excellent capacity retention(99.5%)after 500 cycles at 0.5 C,and high areal capacity(7.08 mAh·cm^(−2)).
