NORMAN, Okla. – NAWA Technologies, a multi-award winning startup based in the South of France, proposes a new generation of batteries that can be recharged in seconds. The system called Ultra Fast Carbon Batteries use the principle of ultra-capacitor.

Although during the past years the ultra-capacitor technology has exponentially increased, the Ultra Fast Carbon Batteries went to the next level. According to NAWA Technologies, the special coating added on its vertically aligned carbon nanotube electrodes cove boost by five times the power density than existing ultra-capacitors.

The ultra-capacitors have several assets compared to lithium-ion batteries: lighter, faster to recharge and discharge, long life up to one million cycles, no overheating, almost no internal resistance and contains nearly no harmful chemicals or toxic metals.

But when the ultra-capacitor has a higher power density than the lithium-ion battery it also has lower energy density than its competitor, affecting how long it will run for. Therefore limiting the market to specific needs.

Better than the existents ultra-capacitors on the market, but still not enough to replace the lithium-ion batteries, the Ultra Fast Carbon Batteries sit between both technologies.

“We are looking to use the technology when charging and discharging time are short,” said by phone Pascal Boulanger, the co-founder and chief operating officer at NAWA Technologies to Red Dirt Report. Boulanger’s career includes among other 10 years in charge of Research Projects within the French Alternative Energies and Commissariat Energie Atomic.

Boulanger said the technology is extremely suitable to using for automatized vehicles such as reach truck for warehouse, airports and harbor. And can also work for shared Autonomous vehicles to transport people for short distance (up to 20 miles) in cities.

“Our technology as the capacity to propose new business models in transportation,” Boulanger said.

Even if the batteries proposed by NAWA Technologies can’t replace the lithium-ion technology for electric cars, Boulanger said it can greatly increase cars’ range when both technologies are coupled together. According to Boulanger, replacing 30 percent of the lithium battery in an electric car by an Ultra Fast Carbon Battery will reduce the volume and weight of the overall batteries by factor two and increase the range by two times. Boulanger added such result is possible if the electric car is doing a lot of braking/acceleration cycles to store and used back the energy kinetic quickly.

“For the same price,” Boulanger said, adding the combination is even more effective for powerful engines such as bus and streetcar.

Far to be limited to logistics and transportations the dedicated applications are numerous: spatial for satellites and launchers, recharge terminals for electric cars, grid security, storage for intermittent renewable energy and electric tools.

Another advantage of the Ultra Fast Carbon Battery and other similar ultra-capacitor is that it’s made of carbon. Carbon is one of the most common element on Earth (biomass, graphite, diamond, in the air,…), making it easy to produce for industrial use.

“This is another strength of our batteries, we produce directly our carbon,” he said.

NAWA Technologies is currently working with numerous European corporations and organizations such as among other the European Space Agency, EDF Energy and the French Alternative Energies and Atomic Energy Commission.

Boulanger expects to start the industrial production of its Ultra Fast Carbon Batteries in few years.

“We hope to show that this technology has a place in the global energy mix,” Boulanger said. “It provides a storage more virtuous, cleaner and safer.”

And for now, the analysts seem to give reason to Boulanger as forecasts are regularly revised upward. The last report published by Research and Markets on October 2016, predicted an increase of the compound annual growth rate about 21.1 percent over the next decade to reach approximately $9.88 billion by 2025.
