What we do

Power Roll has invented a fundamentally new way to generate and store energy.

Our technology is based on a flexible film patterned with thousands of microgrooves. The grooves are a few microns thick - smaller than a human hair.

Capacitors

Our flexible film enables roll-to-roll manufacturing of capacitors using a range of dielectrics and storage materials. Our capacitor technology offers:

Ultra-low cost manufacturing

Multiple shapes and sizes with voltage and capacitance flexibility

Exceptional energy density

Enhanced operating lifetime compared with wet electrolytic capacitors

Future opportunities include low-cost and high-voltage supercapacitors and higher energy and power density storage devices.
