Defect engineering of hollow porous N, S co-doped carbon spheres-derived materials for high-performance hybrid supercapacitors

Nanosheet floral clusters of Fe-doped Co3O4 for high-performance supercapacitors

“…6–8 In particular, electrode materials are a crucial component and essential component of supercapacitors. Supercapacitor electrode materials can be broadly classified into three categories: carbon-based materials, 9 conductive polymers, 10 and compounds based on transition metals. 11 Each category has pros and cons of its own.…”
