Regulating the d band in WS2@NC hierarchical nanospheres for efficient lithium polysulfide conversion in lithium-sulfur batteries

Jintao Liu et al.

Summary: A versatile route to prepare multi-functional nanocomposites with tuable hierarchical structure via ammonium hydroxide induced self-assembly was reported for improving the performance of lithium-sulfur batteries. The as-prepared WS2@NC composite exhibits superior performance due to higher surface area and total pore volume, easier access to electrolyte, better volume change buffering ability, and more prominent shifting and charge compensation from d band of W compared to Co. The density function theory calculation reveals the higher binding energy towards LiPSs and lower energy barrier for Li+ diffusion on the surface of WS2, contributing to enhanced electronic concentration and more hybridization of d-p orbitals in the Fermi level for improved lithium polysulfide interfacial redox and conversion dynamics.
