Technical FAQs 4

What are skeleton supercapacitors used for?

Founded in 2009, Skeleton’s supercapacitors are used in transport, grid, industrial, and automotive applications and allow to reduce CO2 emissions and save energy.

Where are the three Estonian scientists now?

Next year, Skeleton will open the largest supercapacitor factory in Europe, producing twelve million cells a year. As the new generation of engineers is taking over, the three Estonian scientists are remaining in their small town in Tartu where it all started. Marian Männi is an Estonian investigative journalist.

What are supercapacitors & Super batteries?

Supercapacitors in industry standard D60 and D33 form factors, offering reliable high power, low ESR (1S 0.2-1.6mΩ) with 20+ years of lifetime. SuperBatteries fills the gap between supercapacitors and Li-ion batteries, offering the ideal combination of energy, power, and safety.

Why are supercapacitors important?

Supercapacitors are essential for producing and storing green energy. The curved graphene invented by Leis, Arulepp and Perkson made the existing supercapacitors much more efficient. They could keep and provide bursts of energy better than other commercial carbons, withstanding over one million charge cycles.
