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.
