Flexible, all-solid-state cells.
(a) Pictorial representation of an all-solid-state flexible electrochemical capacitor cell; (b) Typical galvanostatic charge/discharge curves of metal/PPy hollow nanoparticles measured at a current density of 0.1 A g−1; (c) Specific capacitances measured at different current densities; and (d) Calculated coulombic efficiencies.
