Tailoring Cathode–Electrolyte Interface for High-Power and Stable Lithium–Sulfur Batteries

This review delves into the mechanism of the state-of-the-art lithium–sulfur batteries from a novel perspective of cathode–electrolyte interface. It provides extensive strategies to construct a stable cathode–electrolyte interphase layer and improve the uneven deposition of Li₂S, enhancing the stability of the interface structure. It proposes an in-depth and comprehensive research on how to inhibit the shuttle effect at the cathode–electrolyte interface with regard to distinct reaction pathways.
