Niobium Phosphide‐Induced Sulfur Cathode Interface with Fast Lithium‐Ion Flux Enables Highly Stable Lithium–Sulfur Catalytic Conversion

Abstract Research on the Li−S catalytic chemistry primarily focus on the development of high‐performance catalysts and the exploration of their reaction mechanisms, with limited attention given to the impact on the interface at the cathode. Moreover, regulating the Li + flux at the cathode interface can enhance Li 2 S conversion kinetics without compromising the intrinsic catalytic activity of catalyst. This work presents a paradigm that employs interface regulation to enhance Li−S battery (LSB) cycling stability. A novel phosphorus doped carbon supported niobium phosphide nanocrystals (NbP/PC) catalyst is developed and demonstrates exceptional intrinsic activity for lithium polysulfide conversion while it…
