Hybrid supercapacitors combine battery-like and capacitor-like electrodes in a single cell, integrating both faradaic and non-faradaic energy storage mechanisms to achieve enhanced energy and power densities [190]. These systems typically employ a polarizable electrode (e.g., carbon) and a non-polarizable electrode (e.g., metal or conductive
The power–energy performance of different energy storage devices is usually visualized by the Ragone plot of (gravimetric or volumetric) power density versus energy density [12], [13].Typical energy storage devices are represented by the Ragone plot in Fig. 1 a, which is widely used for benchmarking and comparison of their energy storage capability.
Polymer nanodielectrics present a particularly challenging materials design problem for capacitive energy storage applications like polymer film capacitors.
