In this work, we demonstrate, scalable spray technique and a chemical treatment method to fabricate high-performance SSCs on carbon cloth using PEDOT:PSS-rGO (20w%) composite. H3PO4 acid SC devices fabricated from chemically treated PEDOT:PSS-rGO electrodes and PVA-H3PO4 gel electrolyte operates at high voltage (voltage window of 0~2.0V), yielding high areal and specific capacitance of ~3000 mF/cm2 and ~170 F/g, at the scan rate of 5 mV/s. Large area (25.0 cm2) devices have high specific capacitance of ~64 F/g. The SC devices have high cyclic and bending stability. Our spray manufacturing approach provides a new way to fabricate high power, large area, wearable energy storage devices. |
