Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
Unlike batteries, electrochemical capacitors (ECs) can operate at high charge and discharge rates over an almost unlimited number of cycles and enable energy recovery in heavier-duty systems. Like all capacitors, ECs (also called supercapacitors or ultracapacitors because of their extraordinarily high capacitance density) physically store charge.
Dielectric electrostatic capacitors have emerged as ultrafast charge–discharge sources that have ultrahigh power densities relative to their electrochemical counterparts 1. However, electrostatic capacitors lag behind in energy storage density (ESD) compared with electrochemical models 1, 20.
The mechanism of charge storage in electrochemical capacitors has traditionally been attributed to the electrosorption of ions on the surface of a charged electrode to form an electrical double layer 16.
Dielectric electrostatic capacitors 1, because of their ultrafast charge–discharge, are desirable for high-power energy storage applications. Along with ultrafast operation, on-chip integration can enable miniaturized energy storage devices for emerging autonomous microelectronics and microsystems 2, 3, 4, 5.
Interestingly, they have an extremely robust stability, with a capacitance retention of 100% for up to 65,000 cycles, demonstrating a superior overall energy storage performance that is highly promising for practical applications in advanced energy storage devices.
Miniaturized energy storage devices, such as electrostatic nanocapacitors and electrochemical micro-supercapacitors (MSCs), are important components in on-chip energy supply systems, facilitating the development of autonomous microelectronic devices with enhanced performance and efficiency.
