A novel type of fiber asymmetric supercapacitor was fabricated by assembling a CoSe2@PPy core/shell nanoflower positive electrode and an EACF negative electrode. Full cells show good flexibility, high-rate capacity, outstanding volume specific capacitance, high volume energy density and are used to power mini-scale photodetectors.
