How do supercapacitors store energy?
Supercapacitors are energy storage devices that store energy through electrostatic separation of charges. Unlike batteries, which rely on chemical reactions to store and release energy, supercapacitors use an electric field to store energy. This fundamental difference endows supercapacitors with several unique properties.
Are supercapacitors the future of energy storage?

Among these technologies, supercapacitors have emerged as a significant innovation, offering unique advantages over traditional energy storage systems such as batteries.
What are supercapacitors used for?
Supercapacitors have seen increased use recently as stand-alone as well as complementary devices along with other energy storage systems such as electrochemical batteries.
Could supercapacitors be an alternative electrochemical energy storage technology?
Therefore, it is believed that supercapacitors can be a potential alternative electrochemical energy storage technology to that of widely commercialised rechargeable batteries especially lithium-ion batteries.
Do supercapacitors have a high energy density?
1) The energy densities of electrochemical capacitors are not high. Currently, there remains a noticeable gap between the energy densities of supercapacitors (<20 Wh kg −1) and batteries (30–200 Wh kg −1). [474 - 476] Improving energy storage density continues to be a key research focus and challenge in the field of supercapacitors.
What is a supercapacitor based on?
A supercapacitor has owned some internal resistance, resulting in energy loss. It can be modeled as a system consisting of a capacitor in series with a resistor (RES), as depicted in Figure 10. The RES is the resistance of the electrochemical capacitors and is important in reflecting the energy efficiency and power performance of supercapacitors.
