Also known as an ultracapacitor or Electrical Double-Layer Capacitor (EDLC), supercapacitors possess a very high capacitance value compared to other regular capacitors. These high-capacitance capacitors have low voltage limits. A major reason for choosing these capacitors over regular ones is that they feature higher power density.
Supercapacitors, also called ultra capacitors or double layer capacitors, are specially designed capacitors that possess very large values of capacitance—as high as 12,000 F. They can be recharged very quickly and are used primarily for energy storage. Supercapacitor construction and operation. (Image: ES Components.) How do supercapacitors work?
The specific power of supercapacitors far exceeds that of the lithium-ion battery. Since supercapacitors charge and discharge so quickly, they are excellent candidates for energy storage during regenerative braking of hybrid and electric vehicles. Supercapacitors are also being applied to large-scale energy storage in renewable energy applications.
Also, please take a look at the list of 19 supercapacitor manufacturers and their company rankings. Here are the top-ranked supercapacitor companies as of October, 2025: 1.SPEL TECHNOLOGIES PRIVATE LIMITED, 2.Taiwan Zhifengwei Technology Co., Ltd., 3.CDE. What Is a Supercapacitor?
