Transforming Waste into Valuable Resources: Mo₂C Nanoparticles Modified Waste Pinecone-Derived Carbon as an Effective Sulfur Host for Lithium-Sulfur Batteries.

ABSTRACT: In this paper, the natural waste pinecone as a carbon precursor for the generation of satisfactory sulfur host materials in lithium-sulfur batteries was realized by introducing molybdenum carbide nanoparticles into the derived carbon structure. The conductive pinecone-derived carbon doped with N, O reveals an expansive specific surface area, facilitating the accommodation of a higher sulfur load. Moreover, the integration of Mo₂C nanoparticles also significantly enhances its chemical affinity and catalytic capacity for polysulfides (LiPSs) to alleviate the shuttle effect and accelerate sulfur redox conversion. As a result, the WPC-Mo₂C/S electrode displays excellent electrochemical performance, including a low capacity decay rate of 0.074% per cycle during 600 cycles
