NanoGraf Corporation has developed a novel high-energy density Si-based anode material that has the long-term potential to replace graphitic-based anodes in lithium-ion batteries for a range of applications, from consumer electronics to electric vehicles.

Connor Hund says NanoGraf aims to onshore production of its silicon-anode material at a new Chicago facility beginning in Q2 this year. The company, whose backers include the Department of Defense, claims to have created the most energy-dense 18650 cylindrical cell yet, at 3.8 amp-hours. The technology key is a pre-lithiated core that allows an anode silicon percentage as high as 25 percent, versus cells that typically top out at 5-to-7 percent silicon.

AZoM talks with Francis Wang, CEO of NanoGraf, to discuss their new lithium-ion battery technology and the onshoring of production in the Midwest.

NanoGraf, a lithium-battery startup, has raised $65 million to help it build up its Chicago production facilities, joining a wave of investment that has poured into US battery manufacturers.

Volta Energy Technologies and CC Industries led the round, which brings the total amount raised by NanoGraf to about $100 million, the company plans to announce Tuesday.

Q&A with NanoGraf COO Connor Hund

Graphite, a pure form of carbon, is a critical material for battery anodes. Graphite’s physical structure allows it to store lithium ions, which merrily migrate to the anode when the battery is charged. Unlike cathodes, which can be composed of various combinations of chemicals (cobalt, nickel, manganese, lithium, iron, phosphorus et al), all current anodes used in EV batteries are composed mainly of graphite.

Battery-technology startup NanoGraf has raised $65 million to ramp up production at a West Side factory that will open later this year. Warrenville-based Volta Energy Technologies and CC Industries, the Crown family's holding company, led the investment. TechNexus and five other investors also joined the round, with existing backers, including Hyde Park Angels and Evergreen Climate Innovations.

Start-ups hoping to commercialize silicon materials for battery anodes raised nearly half a billion dollars in the final quarter of 2022. The money is intended to help them build factories and incorporate their materials into mass-market electric vehicles in the next few years.

Next-gen battery tech is expected to change the economics of EVs, grid-scale renewable power, and other energy-intensive applications. Learn about what's inside the cells that will be coming to market over the next decade.

NanoGraf CEO Francis Wang explains the silicon-anode advantages that made it possible and its implications for the US military and others.

“If you told me this is a 10-year play, I would say, yeah, that makes total sense,” Chip Breitenkamp, president of battery materials company NanoGraf, told TechCrunch. “I think 2024, 2025 is really aggressive for what they’re trying to do and the stipulations they put on the tax credit.”

Recycling electric car batteries is the next big space to watch as the first wave of electric and hybrid vehicles begins to retire from the streets.

“I’m a huge bull on recycling,” Breitenkamp said.

Our CEO, Francis Wang, talked to Wall Street Journal technology reporter Christopher Mims last week about battery market supply chain challenges (including the graphite shortage), and their impact on the “other electric vehicle” – E-bikes. We were excited to see his comments run in this weekend’s edition of the WSJ.
