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.
Nawa's ultracapacitors offer an interesting alternative (or augmentation) to lithium battery systems. When it comes to fast charging or discharging, there's simply no contest – they can pick up or pump out power at rates that absolutely demolish lithium cells, meaning that charging is next to instantaneous – we're talking sub-20 seconds for a full charge – and they're unparalleled for quick bursts of huge power.
Their energy density isn't great compared to batteries, storing maybe a quarter of the power lithium units can for a given volume, but compared to other ultracapacitors their carbon nanotube structure crams up to five times more energy in. They're useless for longer-term storage, leaking somewhere between 10-20 percent of their energy per day, but on the other hand, they last up to a million cycles and are exceptionally durable across a range of temperatures and environments that might test the limits of standard batteries, such as space, high-temp drilling or undersea.
We've covered the technology before, including an interview with Nawa's CEO and COO last year. And now, the company has announced that it's raised the capital and laid down the roadmap to get these things into mass production within the next 12 months.
