Supercapacitors are a new type of capacitors whose capacitance far exceeds the capacitance of traditional capacitors and have ultra-high-energy storage density. By storing opposite charges on two isolated plates, supercapacitors can store large amounts of energy. Unlike traditional capacitors, supercapacitors no longer use solid dielectrics but use electrostatic double-layer capacitors and electrochemical pseudocapacitors.
Compared with traditional batteries, supercapacitors have higher power density (300W/kg~5000W/kg, about 5~10 times that of batteries), faster charge and discharge speed(charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacity), and more charge-discharge cycles (deep charge and discharge cycles can be used up to 1 to 500,000 times, which means longer service life), and higher storage and discharge efficiency (high current energy cycle efficiency exceeds 90%).
Supercapacitors are mainly used in scenes that require rapid charge and discharge cycles and short-term energy storage. At present, they have been used in the car's start-stop system(When decelerating or stopping for a short time, the kinetic energy is converted into electrical energy and stored in the super capacitor, and then the capacitor is discharged during acceleration to achieve the purpose of fuel-saving), super capacitor buses, urban rail transit, and logistics trucks and other fields have started the commercialization process.
At the same time, it has great development prospects in wind power generation, photovoltaic power generation, elevators, port machinery, and data center rapid start, and traditional consumer electronics fields such as mobile phones. It is an important part of future energy storage devices.
