dc.description.abstract | We report on the on-chip fabrication of high performance flexible micro-supercapacitor (MSC) arrays with hybrid electrodes of multi-walled carbon nanotube (MWNT)/V2O5 nanowire (NW) composites and a solid electrolyte, which could power the SnO2 NW UV sensor integrated on the same flexible substrate. The patterned MSC using hybrid electrodes of MWNT/V2O5 NW composites with 10 vol% of V2O5 NWs exhibited excellent electrochemical performance with a high volume capacitance of 80 F cm(-3) at a scan rate of 10 mV s(-1) in a PVA-LiCl electrolyte and good cycle performance to maintain 82% of the capacitance after 10 000 cycles at a current density of 11.6 A cm(-3). The patterned MSC also showed an excellent energy density of 6.8 mW h cm(-3), comparable to that of a Li-thin film battery (1-10 mW h cm-3), and a power density of 80.8 W cm(-3) comparable to that of state-of-the-art MSCs. In addition, the flexible MSC array on a PET substrate showed mechanical stability over bending with a bending radius down to 1.5 mm under both compressive and tensile stress. Even after 1000 bending cycles at a bending radius of 7 mm, 94% of the initial capacitance was maintained. Furthermore, we have shown the operation of a SnO2 NW UV sensor using such a fabricated MSC array integrated into the same circuit on the PET substrate. | - |
