A 1.8 V asymmetric solid-state flexible micro-supercapacitor is designed with one MnO2-coated reduced graphene oxide/single walled carbon nanotube (rGO/SWCNT) composite fiber as positive electrode and one nitrogen-doped rGO/SWCNT fiber as negative electrode, which demonstrates ultrahigh volumetric e...
