Controllable Substitution of S Radicals on Triazine Covalent Framework to Expedite Degradation of Polysulfides

Lithium–sulfur (Li–S) batteries are facing a significant barrier due to the diffusion of intermediate redox species. Although some S doped covalent framework cathodes have been reported with outstanding reversibility, the low content of sulfur (less than 30%) limits the practical applications. To ov...
