description | For the development of light, flexible, and wearable electronic devices, it is crucial to develop energy storage components combining high capacity and flexibility. Herein, an all-solid-state supercapacitor is prepared through an in situ growth method. The electrode contains polyaniline deposited on a carbon nanotube and a poly (ethylene-co-vinyl acetate) film. The hybrid electrode exhibits excellent mechanical and electrochemical performance. The optimized few-layer polyaniline wrapping layer provides a conductive network that effectively enhances the cycling stability, as 66.4% of the starting capacitance is maintained after 3000 charge/discharge cycles. Furthermore, the polyaniline (PANI)-50 displays the highest areal energy density of 83.6 mWh·cm(−2), with an areal power density of 1000 mW·cm(−2), and a high areal capacity of 620 mF cm(−2). The assembled device delivers a high areal capacity (192.3 mF·cm(−2)) at the current density of 0.1 mA·cm(−2), a high areal energy (26.7 mWh·cm(−2)) at the power density of 100 mW·cm(−2), and shows no significant decrease in the performance with a bending angle of 180°. This unique flexible supercapacitor thus exhibits great potential for wearable electronics. |
