The service life of the supercapacitor in the car is more than 5 years.
Supercapacitor (super
capacitor, also known as electrochemical capacitor, double electric layer capacitor, is a new type of capacitor, its appearance makes the limit capacity of the capacitor suddenly rise by 3 to 4 orders of magnitude, reaching a large capacity of 1 F\/g level or more. Because supercapacitors can charge and discharge in a few seconds, the performance loss is very low, so supercapacitors in daily use, without special maintenance, integrated in the lithium battery battery, supercapacitors can also provide instant power, reduce the number of charge and discharge of lithium batteries, extend the life of lithium ion batteries and the entire energy system.
