【 摘 要 】

tsCNT/MnO2/graphene-grafted carbon cloth electrode is designed and achieves high MnO2 mass loading (9.1 mg cm−2).The electrode with favorable electronic/ionic conductivity delivers a large areal capacitance and rate capability.The assembled asymmetric supercapacitor yields a large energy density of 10.18 mWh cm−3.
