Supercapacitors for energy storage: Fundamentals and materials
Among various electrochemical energy-storage devices, electrochemical capacitors (supercapacitors) and batteries have been extensively studied and widely used for a range of
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.
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.
Supercapacitors bridge the gap between traditional capacitors and batteries. It has the capability to store and release a larger amount of energy within a short time . Supercapacitors hold comparable energy storage capacity concerning batteries.
Most prominently, solar, wind, geothermal, and tidal energy harvesters generate electricity in today's life. As the world endeavors to transition towards renewable energy sources, the role of supercapacitors becomes increasingly pivotal in facilitating efficient energy storage and management.
