  • NanoGraf announced it raised $65 million. These are the details.

NanoGraf – an advanced battery materials company and enabler of the world’s most energy-dense lithium-ion 18650 cell – announced that it has raised $65 million in an oversubscribed Series B funding round.

This funding round was co-led by Volta Energy Technologies and CC Industries (CCI) with participation from Emerald Technology Ventures, Material Impact, Arosa Capital, Nabtesco Technology Ventures, and TechNexus. The existing investors including Hyde Park Angels, Evergreen Climate Innovations, and Goose Capital also participated in the round. NanoGraf previously raised a total of $27 million in funding from a mix of the venture, angel, and non-dilutive funding sources.

The U.S. battery supply chain issues brought on by unprecedented market demand is prevalent now more than ever and NanoGraf is committed to onshoring key strategic components of the battery supply chain, aligned with President Biden’s Inflation Reduction Act for clean energy and infrastructure projects. And NanoGraf’s Series B funding supports onshoring of its silicon anode production in Chicago, as well as the continued development, production and supply of advanced lithium-ion technologies.

The announcement of the Series B funding comes on the heels of two major announcements for NanoGraf. And in November of 2022, the company was awarded a $10 million contract from the U.S. Government to develop the first advanced silicon anode manufacturing facility in the Midwest. One month before, NanoGraf set a new industry benchmark for the most energy-dense lithium-ion 18650 cell, with more than 20% higher energy density than the industry’s leading cells today.

NanoGraf is an advanced battery material company whose patented silicon-anode technology enables longer-lasting, higher-energy, and higher-power lithium-ion batteries. And NanoGraf works with over 50 companies, including some of the world’s leading consumer electronics, household appliance, and power tool brands, and over 12 strategic partners in electric mobility (from startups to Fortune 100s). NanoGraf is a spinout of Northwestern University and Argonne National Laboratory.


“NanoGraf’s breakthrough silicon technology further exemplifies our commitment to extending the energy and power performance characteristics of today’s lithium-ion batteries for a sustainable electrified future. I’m incredibly proud of the technologies and products our team has developed over the last 36 months. This funding not only ensures a domestic supply of a key strategic component of next generation lithium-ion batteries, but also enhances our national competitiveness in the global energy storage space.”

— Dr. Francis Wang, CEO of NanoGraf

“Nanograf’s technology promises to enable higher energy density in lithium-ion batteries, in a way that uses silicon with what is practically drop-in to existing battery manufacturing processes. Volta is excited to add Nanograf to its growing portfolio of advanced technology that will be part of the important supply chain of advanced battery and related technology. We are equally enthused by the quality of the group of investors in this round of financing being announced today.”
