Summary: This article introduces a method for synthesizing heteroatom-doped carbon materials using poly(ionic liquid) as precursors. Polydopamine coating and ion exchange were used to successfully apply imidazolium-based poly(ionic liquid) nanovesicles in morphology-maintaining carbonization, preparing carbon composite nanocapsules. The strategy was further extended to synthesize carbon composite nanocapsules functionalized with iron nitride nanoparticles. This well-crafted composite nanostructure effectively mitigated the shuttle effect of lithium polysulfides in Li-S batteries, showing excellent electrochemical performance.
