Are supercapacitors a good energy storage device?

Supercapacitors are among the most promising electrochemical energy-storage devices, bridging the gap between traditional capacitors and batteries in terms of power and energy density. Their charge-storage performance is largely influenced by the properties of electrode materials, electrolytes and the underlying charge-storage mechanisms.

How does a supercapacitor work?

A supercapacitor is an electrochemical variant of a capacitor, consisting of two electrodes separated by an electrolyte, which stores energy either through electrostatic charge accumulation or via electrochemical charge transfer at the electrode–electrolyte interface.

What are electrochemical energy storage devices?

Among various electrochemical energy-storage devices, electrochemical capacitors (supercapacitors) and batteries have been extensively studied and widely used for a range of applications. The energy-storage mechanisms in capacitors and batteries differ significantly.

Which polymers are used in supercapacitor application?

Restacking of the layers largely limits the capacitive performance. Highly conductive and redox-active polymers, including polypyrrole, polyaniline, polythiophene, poly (3,4-ethylenedioxythiophene), etc. and their composites are widely used for supercapacitor application.
