Weavable, High‐Performance, Solid‐State Supercapacitors Based on Hybrid Fibers Made of Sandwiched Structure of MWCNT/rGO/MWCNT

Weavable, high-performance, solid-state supercapacitors are prepared based on hybrid fibers made of sandwiched structure of multi-walled carbon nanotube (MWCNT)/reduced graphene oxide (rGO)/MWCNT. Such supercapacitors exhibit excellent weavability, high volumetric capacitance and energy density, and good cycling stability owing to the high mechanical property and electrical conductivity of well-aligned long MWCNTs, the incorporation of rGO nanosheets, and the unique sandwiched hybrid structure.
