SuperBattery
SuperBattery power
for a net-zero future


Skeleton’s technology, providing ultrafast charging at ~< 90 seconds, means the solution can help mining companies reduce emissions without compromising on efficiency.”


What is SuperBattery?
While Ultracapacitors excel at short-term energy storage in the range of milliseconds up to 60 seconds, they lack the energy density to provide meaningful energy storage at longer timescales.
Lithium-Ion batteries, on the other hand, are energy dense but lack the power density to be efficient below 15 minutes charge/discharge time, which leads to battery systems often being overscaled up to 6 times.
Skeleton’s SuperBattery technology has been developed to fill this technological gap in the energy storage market, delivering peak power within 30 seconds, while still being able to support up to 30 min of charge/discharge events due to an energy density of up to 65 Wh/kg.



SuperBattery Cells
High energy throughput, high power, and long lifetime in a safe, industry-standard form factor
Skeleton's SuperBattery energy storage cells are based on our proprietary Curved Graphene raw material, allowing for a long lifetime (50,000 charge-discharge cycles), high power, energy density comparable to high-power batteries, and excellent safety.
The first SuperBattery cells come in the supercapacitor industry standard D60 large cell form factor.
