Lithium-sulfur (Li-S) is one of the most promising rechargeable batteries due to its high theoretical specific capacity, abundance, and low cost. Li-S batteries, however, suffer from detrimental volumetric changes, poor electrical conductivity, and polysulfide shuttling. To overcome these problems, current approaches mostly focus on chemical processes. Herein, we have developed two different physical strategies for suppressing the shuttle effect. The first method involves the deposition of metal thin films, such as Al and Ni, on sulfur cathodes by magnetron sputtering. In the second method, the Al sputtered filter papers with varying pore sizes are sandwiched between the cathode and the separator following the carbonization processes. Thin film coating on the cathode surface and the insertion of the protective interlayer can prevent the diffusion of polysulfides towards the anode, supressing the shuttle effect. The morphological and stuctural properties of the modified electrodes are comprehensively investigated through microscopic and spectroscopic characterization techniques. The electrochemical characterization of the half-cells with modified electrodes is also performed. This study introduces newly developed strategies to improve the cycling stability of Li-S batteries.
