Engineering Hollow-Structured Carbon Framework to Facilitate High-Sulfur-Content Encapsulation for Lithium-Sulfur Batteries.

ABSTRACT: Lithium-sulfur batteries (LSBs) have emerged as promising candidates for next-generation energy storage systems due to their high theoretical energy density and cost-effectiveness. However, their practical application is severely limited by the shuttle effect of lithium polysulfides (LiPSs) and the inherently low electrical conductivity of sulfur, which leads to rapid capacity fading and poor rate performance. To address these challenges, this work develops a hollow-structured graphitic nitrogen-doped porous carbon (h-GNPC) framework derived from zeolitic imidazolate framework-8 via a magnesiothermic reduction (MR) process. This method effectively tailors the pore architecture and electrical conductivity, enabling efficient sulfur encapsulation and high sulfur loading up to 90 wt.%. Compar
