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.
The accelerating global demand for sustainable and efficient energy storage has driven substantial interest in supercapacitor technology due to its superior power density, fast charge–discharge capability, and long cycle life. However, the low energy density of supercapacitors remains a key bottleneck, limiting their broader application.
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.
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.
