NAWA Plans to Use Nanotube Ultracapacitor to Power EVs

Battery density is one of the most significant challenges facing electric vehicles. French company NAWA Technologies intends to use its Ultra Fast Carbon Battery to help solve the problem.

Ultra Fast Carbon Battery

NAWA's Ultra Fast Carbon Battery is an ultracapacitor built from carbon nanotubes. The technology will be used in a dual energy system along with lithium-ion batteries.

The company claims its design can deliver up to five times more power and energy density than traditional ultracapacitors. This is due mostly to the unique coating applied to the nanotubes.

CEO Ulrik Grape expands on the concept, "The unique aspect of the technology of our Ultra Fast Carbon Battery is our successful development of vertically aligned specially coated nanotubes, allowing us to increase the energy density of the carbon nanotubes or basic capacitor."

"We can accept the charge and release it exceptionally fast," he said. "This is a high power technology that can assist the automotive sector's requirement to achieve ever greater energy density." 


NAWA, hopes the technology will have a lifespan and charging speed superior to current lithium-ion batteries. The firm predicts the nanotube-filled Ultra Fast Carbon Battery will have a recharge time of just seconds and last up to a million cycles. Long life comes from the ultracapacitor's ability to do the system's heavy lifting.

Fast charging and extended service are just a couple of the benefits associated with The Ultra Fast Carbon Battery. Another perk is quick power delivery from the capacitors under heavy acceleration. The technology can also collect an exceptional amount of energy during regenerative braking.

And then there's the weight reduction. NAWA believes the hybrid ultracapacitor and lithium-ion set up can substantially reduce system heft.

Making it a reality

Such technology certainly sounds pricey. But NAWA believes it will cost much less than the ultracapacitors available now. Currently, Ultra Fast Carbon Batteries are going through a pilot program at NAWA's R&D facility.

Once released on the market, the technologies first application is likely to be power tools. NAWA says automotive use is still four to five years out.
