What are the Popular Supercapacitor Products?
I. Introduction
Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are energy storage devices that bridge the gap between traditional capacitors and batteries. They store energy through electrostatic charge separation, allowing for rapid charge and discharge cycles. In recent years, supercapacitors have gained significant attention due to their unique properties, such as high power density, long cycle life, and the ability to operate in a wide temperature range.

II. Understanding Supercapacitors
A. Basic Principles of Supercapacitor Operation
Supercapacitors operate on two primary principles: electrochemical double-layer capacitance and pseudocapacitance.
1. **Electrochemical Double-Layer Capacitance**: This occurs at the interface between an electrode and an electrolyte, where ions accumulate, creating a double layer of charge. This mechanism allows supercapacitors to store energy quickly and release it rapidly.
2. **Pseudocapacitance**: This involves fast redox reactions at the electrode surface, allowing for higher energy storage than traditional capacitors. Pseudocapacitance contributes to the overall capacitance of the supercapacitor, enhancing its energy density.
