Nanotech Batteries That Last 9 Times Longer

Nanom is unveiling a patented technology that uses nanoparticles to make batteries that are far more efficient than the ubiquitous lithium-ion version used today.

If it works, the technology could revolutionize batteries used in everything from electric cars to laptops and smartphones. Nanom claims its batteries last 9 times longer than the nickel-iron batteries Thomas Edison invented and more than than 9 times longer than lithium-ion batteries. They also weigh 5 times less and improve energy density, recharge rates, and battery disposal.

Nanom isn’t disclosing the direct comparison to lithium-ion batteries yet. But it is saying that an electric car with Nanom tech could drive across the United States on a single battery charge. That’s pretty mind-boggling.

And the company has raised $3 million from investors in Silicon Valley and the Nordics, thanks to backers like Village Global, whose network includes Bill Gates, Jeff Bezos, and Reid Hoffman.

A big advantage of the nanotechnology Nanom uses is that it can be applied to existing lithium-ion batteries, creating more surface area to generate energy with the battery cells. Nanom can make the tech in its labs and easily add production to existing manufacturing plants.

“The problem has always been that nanotechnology has been a little bit stuck in the lab,” CEO Armann Kojic said in an interview with VentureBeat. “It’s like a concept that has been great for making a million-dollar battery, but not one that actually goes in your car. And what’s unique about our approach is the fact that our core method of creating nanoparticles is a mass production method. This is very much about bringing it out of the lab and into a product.”

The Edison nickel-iron battery is more than 120 years old. Using iron and nickel particles and carbon fiber, Nanom makes the battery usable again. The company says its materials are 80% cheaper than those in a regular battery — and more disposable. The nickel-iron battery is used in large-scale energy storage devices.

“The Edison battery is kind of a showcase for us … to show what could be done to take a green battery and counter the weaknesses,” Kojic said.

Nanom is talking to a wide range of transportation, stationary storage, and battery companies about immediately adopting its nanoparticles into their own proprietary designs.

“We all know that this battery problem exists,” Kojic said. “And there’s a lot of factors that need to come together, like the environmental factor, the cost factor, and the effectiveness of the battery.”

Nanom’s nanoparticle technology enables any battery formulation to be fundamentally altered for the better by dramatically increasing every aspect of its performance. It does so by immersing the battery materials in nanoparticles that increase the surface area that generates energy on a microscopic level.

These particles are many orders of magnitude more effective in increasing energy surface area than the current solutions, which makes them ideal for this generation of battery energy storage. And Nanom immediately enhances the energy density of any battery, Kojic said.

“It’s all about the ultra-high surface area, which affects the charging rates and the capacity,” Kojic said. “If I take a business card, I have the surface area as the front and the back of the business card. But if I cut it into a billion pieces, it becomes several football fields of a surface area, I’m using the sides and everything in between. And we can use all of that unused area for storing energy.”

Nanom has the ability to convert existing battery materials into nanoparticle size, enabling the same benefits for any battery process without needing to retool — the nanoparticles are simply mixed into the slurry that is a standard part of all battery manufacturing lines. Nanom has achieved massive scale in its manufacturing process and can already satisfy the requirements of key battery markets. In that sense, Kojic said the invention is industrially scalable.

The critical barrier to the utilization of the full potential of nanotechnology has always been the inability to economically manufacture nanoparticles in sufficient quantities. Nanom’s method allows for mass production of nanoparticles produced through friction by transverse introduction of feedstock material into alternating supersonic flow regimes in various controlled atmospheres. Controlling flow speed, atmosphere, repetitions, and after treatment allows the company to uniquely shape the particle’s size and surface areas, resulting in a bespoke nanostructure with unique properties. Nanom said it can convert micron-sized particles to nano-sized particles in high volume.

This provides unique nanostructures that enable longer-lasting batteries without changing anything in the batteries’ manufacturing flow. By replacing key materials with nano-enhanced materials, Nanom says it gives customers a competitive advantage.
