Organosulfur‐Rich Porous Carbon Cathode Enables Soluble‐Polysulfide‐Free and High‐Rate Potassium‐Sulfur Batteries

) can be achieved for the OSPC cathodes. Additionally, the feasibility of synthesizing OSPC from real-world waste plastics is demonstrated, which offers a dual benefit of alleviating plastic pollution and enabling the fabrication of low-cost yet high-performance cathodes for K-S batteries.
