Investors bet $27.5 million on Nanotech Energy’s graphene battery breakthrough –…

Nanotech Energy plans to release a non-flammable, environmentally friendly lithium battery that can charge “18 times faster than anything that is currently available on the market.” And it aims to do it within the next year.

From pv magazine USA

In May of this year, battery and graphene tech startup Nanotech Energy closed a $27.5 million funding round at a post-money valuation of $227.5 million. The investors were not disclosed. The company has raised more than $30 million since it was established in 2014.

CEO Jack Kavanaugh recently spoke with pv magazine. His startup claims to be “the world’s top supplier of graphene” and plans to release a non-flammable, environmentally friendly lithium battery that can charge “18 times faster than anything that is currently available on the market.” And it aims to do it within the next year.

This list of leading graphene suppliers does not include Nanotech Energy. Headquartered in Los Angeles, the company was co-founded by Kavanaugh and UCLA scientists Richard Kaner and Maher El-Kady.

“We are confident that we have a one-of-a-kind, industry-changing product that will impact the technologies and bottom lines of multiple end-user markets,” Kavanaugh said.

Although investors in this round were not disclosed, Kavanaugh, along with fellow-board members Mahi De Silva and Robert Snukal, are part of Multiverse Investment Fund, a minority investor in the battery startup, according to Pitchbook.

Graphene can improve the surface area and electronic conductivity of the lithium-ion battery anode and cathode. According to the company, these nanostructured electrodes “enable a new generation of lithium-ion batteries with excellent power density, exceptionally high energy density and long cycling life.”

The startup uses a solution processing method that allows graphene to be coated on “any substrate” along with a laser process step that forms a graphene foam. The company had originally applied its graphene technology to making better supercapacitors, but now focuses on its “super battery.”

Nanotech Energy is commercially shipping graphene inks and the CEO stresses that it is producing “real graphene,” not graphite. Science Mag points out that much of what is sold as graphene is often small pieces of bulk graphite, despite its $300 per gram price. Graphite is used as structural support in tennis racquets and bicycles – but it’s not the 1-atom-thick sheet of monolayer graphene needed to make a better battery.

The CEO said that fabricating its own graphene allows the startup to be vertically integrated. He adds that the firm can produce kilos per day compared to the grams coming from other vendors.

Specs and claims

The CEO said that the company’s technology is being applied to various lithium formulations, as well as a non-lithium, environmentally friendly, water-based electrolyte.

The company claims:

  • Its battery has low resistance – less than 5 mΩ  in…
