SuperBattery benefits

SuperBattery is an innovative technology combining the characteristics of supercapacitors and batteries.

charged in under 90 seconds
Charged in under 90 seconds

Less than 90 seconds of charging, eliminating long charging breaks.

50000 life cycles
50 000 life cycles

SuperBattery has more than 10 times more charge-discharge cycles compared to Lithium-Ion batteries, providing much longer lifetime.

Inherently safe
Inherently safe

No thermal runaways, no need for thermal propagation measures. SuperBatteries are safe, even when pierced, crushed, or overheated.

More sustainable raw materials
