As anode for a flexible supercapacitor, the FeCo<sub>2</sub>O<sub>4</sub>@polypyrrole core/shell nanowiresndisplay a specific capacitance of 2269 F g<sup>–1</sup> atn1 A g<sup>–1</sup>. The specific capacitance retains 79.2%nat 20 A g<sup>–1</sup>. Additionally, a flexible ASC was fabricatednvia combining an FeCo<sub>2</sub>O<sub>4</sub>@polypyrrolenanode with an activated carbon cathode, which achieves an encouragingnenergy density of 68.8 Wh kg<sup>–1</sup> (0.8 kW kg<sup>–1</sup>), and long cycle lifespan (91% over 5000 cycles).
