Skeleton Technologies is the global leader in ultracapacitors and is innovating at the intersection of battery and capacitor technology to deliver high-power energy storage. Founded in 2009 with operations in Estonia and Germany, Skeleton’s ultracapacitors (branded “SuperCaps”) provide instant power and over 1,000,000 charge cycles, used in transportation, grid, and industrial applications. Now, Skeleton is developing the “SuperBattery,” a hybrid system combining its ultracapacitors with chemical batteries to achieve fast charging in 90 seconds and high power output, targeting use in electric vehicles to assist lithium-ion packs. Skeleton’s products use patented “curved graphene” material for unmatched performance. Manufacturing in Grossröhrsdorf, Germany, Skeleton can produce ultracapacitor cells and modules at scale, and it’s building a new gigafactory for ultracapacitors in Saxony. Collaborating with automakers (e.g., Hyundai), Skeleton aims to complement batteries by handling power surges and fast charging, thereby extending battery life. Skeleton’s agile R&D and in-house production of carbon electrodes give it a unique position to boost future EV battery systems with hybrid energy storage.

Skeleton Technologies is a global leader in high-power energy storage specializing in ultracapacitors and hybrid supercapacitor-battery systems. Headquartered in Estonia with production in Germany, Skeleton provides cutting-edge carbon-based ultracapacitor cells and modules that deliver very high power density, fast charging, and over 1 million life cycles. For the e-mobility sector, Skeleton offers innovative solutions like its “SuperBattery,” which combines the characteristics of batteries and ultracapacitors to provide instant power and extend battery life in electric vehicles. Skeleton’s products are used in electric buses, trucks, motorsport, and industrial machinery to improve acceleration, capture regenerative braking energy, and stabilize power networks. With nine IATF 16949 certified manufacturing sites globally, Skeleton meets rigorous automotive quality standards and partners with leading OEMs to integrate its technology for improved efficiency and performance. Committed to constant innovation, Skeleton leverages patented “curved graphene” material to achieve world-record energy density in its class. As the demand for high-power and fast-charging energy storage grows, Skeleton Technologies stands at the forefront, delivering reliable solutions that bridge the gap between batteries and conventional capacitors.
