摘要
Although lithium-sulfur batteries are considered one of the most potential next-generation energy storage systems owing to their high-energy density, the dissolution and shuttle of intermediate lithium polysulfides primarily limit their commercial applications. Currently, the search for new materials for high-performance lithium-sulfur batteries has become a global research hotspot.MXenes, two dimensional inorganic compound comprising several layers of transition metal carbide, nitride, or car-bonitride,are actively investigated owing to their large specific surface area, good conductivity, and excellent cycle and rate performance.This article firstly reviews the breakthrough of MXenes in lithium-sulfur batteries, introduces the preparation methods and structural characteristics, and summarizes the specific applications and modification mechanisms in lithium-sulfur batteries.Then, the characteristics and advantages of MXenes as a composite electrode material for lithium-sulfur batteries are highlighted. Finally, the potential in future commercial applications is summarized.
