Highly flexible conductive electrodes were prepared by screen printing a commercial carbon nanoparticle ink onto various substrates such as clothes, polyethylene terephthalate (PET) and paper. The flexible electrodes showed good stability during the bending test and could act as a foldable electric circuit. Multi-walled carbon nanotubes-manganese dioxide (MWCNTs-MnO2) anodes and multi-walled carbon nanotubes-molybdenum trioxide (MWCNTs-MoO3) cathodes for asymmetric supercapacitors (ASCs) were screen printed onto carbon nanoparticle electrodes, which acted as a collector. The fully screen printed supercapacitor has a wide operating potential window of 1.7 V and exhibits excellent electrochemical performance, e.g. a high energy density of 11.04 mW h cm(-3) at a power density of 614.6 mW cm(-3), a high retention ratio of similar to 91.3% of its initial capacitance after 5000 cycles. The screen-printing acting as a simple, versatile, fast, and cost-effective printing method can be fully integrated with the fabrication process in current printed electronics and has potential applications for energy storage.
