| Abstract Scope |
Among several re-visited chemistries, though rechargeable lithium-sulfur (Li-S) batteries holds a significant promise as the next generation technology to replace lithium ion batteries, their development is still hampered by several challenges such as low cycle life, poor coulombic efficiency, and high self-discharge. As conventional carbon materials have poor adsorption towards dissolved polysulfides, search for alternative sulfur hosts has gained research interest in the Li-S battery field. Here, we preset a role of catalyst at the cathode surface to stabilize polysulfide shuttle process along with enhancement in its redox kinetics. The interaction between catalyst and polysulfide has been evaluated from the insitu spectro-electrochemical studies. The introduction of catalyst-based cathodes in the Li-S system is expected to open a new avenue for improving electrochemical performance. |
