Ultracapacitors

This sweet-looking electric motorcycle has a relatively small, lightweight 9-kWh battery, and yet it boasts a 300-km (186-mi) urban range and superbike-level acceleration thanks to an ultracapacitor hybrid system unlike anything we've seen before.

Charging almost instantly and offering massive power density, Nawa's innovative ultracapacitors are ready to make a mark across industries from automotive to power tools and aviation. And after raising more than US$10 million, this French company is going into mass production.
