Supercapacitors, also known as ultracapacitors or electric double-layer capacitors (EDLCs), are energy storage devices that bridge the gap between traditional capacitors and batteries. They are characterized by their ability to store and release energy rapidly, making them essential components in various modern technologies. As the demand for efficient energy storage solutions continues to grow, understanding the different types of supercapacitors and their applications becomes increasingly important. This article aims to provide a comprehensive overview of the product types of supercapacitors, their characteristics, and their applications in various industries.
Supercapacitors operate on the principle of electrostatic charge storage.
