WebFiber-shaped supercapacitors, which occupy minimal volume and possess remarkable flexibility, are particularly promising candidates for next-generation smart wearable devices. However, the state-of-the-art energy density and mechanical properties of fiber-shaped electrodes are far from satisfactory. WebAn asymmetric all-solid-state supercapacitor (ASC) was fabricated using AC as the anode, MnO 2 @CC as the cathode, and polyvinyl alcohol (PVA)/LiCl gel as the electrolyte. An ultrahigh specific capacitance of 3455.6 mF cm −2 at 1 mA cm −2, a maximum energy density of 1.56 mW h cm −2, and a long lifetime of 10,000 cycles can be achieved.
