Lithium-sulfur (Li-S) batteries have a high theoretical energy density and are regarded to be an ideal choice for the next generation of electrochemical storage systems. However, their practical application is hindered by several bottlenecks, including insulating nature sulfur its discharge products (Li2S2/Li2S), shuttling behavior intermediate polysulfides, slow redox reactions. Herein, we propose highly efficient bimetallic selenide electrocatalyst featuring hollow porous core-shell spherical structure, which serves as both cathode host modified separator coated on commercially available polypropylene address above issues. The enhances conductivity, unique structure provides rapid ion transport channels, along with ample spatial confinement lithium polysulfides. Additionally, abundant reactive sites selenides exhibit intrinsic electrocatalytic activity, accelerating polysulfide conversion improving kinetics. Density functional theory calculations indicate that interact more strongly polysulfides present lower reaction barriers compared those sulfide counterparts. Consequently, these materials demonstrate superior rate performance cycling stability in Li-S batteries, achieving impressive lifespan 1400 cycles minimal decay 0.030% per cycle at 1.0 C. This work insights into enhancing transition metal compounds batteries.
