Lithium-sulfur (Li-S) batteries are receiving a lot of attention as next-generation power sources. Elemental sulfur is a promising cathode material with the advantages of low cost and environmental friendliness as well as high theoretical capacity (1675 mAh/g) and high energy density (2600 Wh/kg). However, the problems caused by the insulation of sulfur, the dissolution of lithium polysulfide intermediates, and volume expansion of electrodes during the lithiation process may lead to low utilization of active materials, serious capacity fading, and safety risks. In order to overcome these problems of Li-S batteries, porous carbons for supporting sulfur, which is an active material, and interlayer films for suppressing the movement of lithium polysulfides have been widely used. In this study, a novel coating interlayer was prepared by using a nano-rod type La_xSr_1-xCo_yFe_1-yO₃ perovskite material for advanced Li-S batteries, which can effectively immobilize the soluble polysulfides and further accelerate the reaction kinetics. The perovskite-type oxide can withstand a significantly high concentration of anion vacancy in a crystal structures, thereby providing a lot of active sites to anchoring polysulfides and further improving the electrochemical performance of Li-S batteries. Therefore, Li-S batteries with the perovskite-type  coating layer can improve the specific capacity and guide an excellent rate capability for Li-S batteries.
