SuperBattery benefits
SuperBattery is an innovative technology combining the characteristics of supercapacitors and batteries.
Less than 90 seconds of charging, eliminating long charging breaks.
SuperBattery has more than 10 times more charge-discharge cycles compared to Lithium-Ion batteries, providing much longer lifetime.
No thermal runaways, no need for thermal propagation measures. SuperBatteries are safe, even when pierced, crushed, or overheated.
SuperBatteries don't use cobalt, nickel, graphite, or copper.
SuperBattery Racks, Modules, & Cells
Skeleton's SuperBatteries provide unmatched reliability, lifetime, and power/energy density. SuperBatteries are available in the forms of cells, or modules, serving customers in AI data centers, grid, automotive & heavy trucks, and aerospace companies.
