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.
Capacitor specifications of capacitance, DC leakage current (DCL), equivalent series resistance (ESR), size, etc. are typically room temperature measurements under a very specific test condition. Furthermore, energy storage capacitors will often be set up in some parallel/series combination that can pose unique challenges or unexpected behaviour.
Simplified diagram of the constitution of an aluminum electrolytic capacitor consisting of aluminum electrodes, an alumina dielectric and an electrolyte. The only physics that can store energy in a capacitor is electrostatics, allowing rapid and reversible processes.
A simple energy storage capacitor test was set up to showcase the performance of ceramic, Tantalum, TaPoly, and supercapacitor banks. The capacitor banks were to be charged to 5V, and sizes to be kept modest. Capacitor banks were tested for charge retention, and discharge duration of a pulsed load to mimic a high power remote IoT system.
As a result, these SCs are being widely considered as preferable alternatives for energy storage applications. Flexible solid-state supercapacitor devices typically consist of many components, such as flexible electrodes, a solid-state electrolyte, a separator, and packaging material .
This comprehensive review has explored the current state and future directions of supercapacitor technology in energy storage applications. Supercapacitors have emerged as promising solutions to current and future energy challenges due to their high-power density, rapid charge-discharge capabilities, and long cycle life.
