Near West Side ventures seed growth in Chicago manufacturing

There’s this weird thing about the entrepreneurial spirit and trying to create jobs from a new idea: It takes intense work and focus but also patience, qualities hard to find in equal measure.

On the Near West Side, within blocks of each other, are examples of two such operations seeing results from its investments of labor, thought and capital. They will be part of an innovation economy taking root in what was Chicago’s old meatpacking and produce district.

NanoGraf Holds Ribbon Cutting for Midwest's First Advanced Silicon Anode Production Facility

NanoGraf announced the grand opening of its new office and manufacturing facility in Chicago’s West Loop neighborhood. U.S. Senator Dick Durbin, Deputy Assistant Secretary of Defense for Industrial Base Resilience Halimah Najieb-Locke, and other confirmed attendees led a ribbon cutting ceremony for the 17,000-square-foot space, the first large-volume silicon oxide manufacturing facility in the U.S.

Illinois’ success in landing an EV battery plant came from defeat

Illinois’ success in landing an electric vehicle battery plant came from defeat.

Nearly a year before China’s Gotion Hi-Tech chose Manteno for a $2 billion battery assembly plant, it picked Michigan for a similar factory. Gov. J.B. Pritzker set about persuading lawmakers to authorize a $400 million deal-closing fund and extend the state’s incentives, primarily payroll-tax credits, to last as long as 30 years. The legislation passed in December and January.

The EV Battery Wish List - Which automakers most want what in their ideal electric powertrain?

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.

How NanoGraf is commercializing the “world’s most energy-dense” 18650 battery cell with stable silicon oxide

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.

Crown family part of $65 million investment in battery startup

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.
