Technical FAQs 4

What is a super capacitor?

Super capacitors, also known as ultracapacitors, stand at the forefront of energy storage technology, offering rapid charging and discharging times, high power density, and extended life cycles compared to traditional batteries.

Are supercapacitors a good choice for energy storage?

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.

What is the specific power of a supercapacitor?

Supercapacitors have a specific power 5 to 10 times greater than that of batteries. For example, while Li-ion batteries have a specific power of 1 - 3 kW/kg, the specific power of a typical supercapacitor is around 10 kW/kg.

Are supercapacitors better than batteries?

Supercapacitors have a competitive edge over both capacitors and batteries, effectively reconciling the mismatch between the high energy density and low power density of batteries, and the inverse characteristics of capacitors.
