Carbon fabric-aligned carbon nanotube/MnO2/conducting polymers ternary composite electrodes with high utilization and mass loading of MnO2 for super-capacitors

▸ Carbon fabric-aligned carbon nanotube (CF-ACNT) acted as a unique substrate. ▸ MnO2 and poly(3,4-ethylenedioxythiophene) (PEDOT) were deposited on CF-ACNT. ▸ The ternary composites showed a high MnO2 utilization of 77.7%. ▸ The 3D porous ternary system allowed large MnO2 mass loading up to 3.11 mg cm−2 ▸ A reasonable area-normalized capacitance of 1.3 F cm−2 was achieved.
