NanoGraf Corporation is a leading developer of advanced silicon-based anode materials for lithium-ion batteries. Since its founding in 2012, the Chicago-based company has focused on creating superior energy storage solutions through innovative silicon-graphene technology. NanoGraf’s proprietary materials significantly enhance battery performance, offering up to 50% increased energy density compared to traditional graphite anodes. The company’s solutions serve various sectors, including electric vehicles, consumer electronics, and military applications, making it an essential player in the U.S. battery supply chain.
Battery Technology
NanoGraf’s primary innovation centers on its silicon-oxide anode material, which represents a significant advancement in battery technology. This proprietary material combines silicon with graphene in a unique composite structure that addresses common challenges in silicon-based anodes, such as volume expansion during charging cycles. The technology enables batteries to achieve higher energy density while maintaining structural stability and longevity.
The company’s latest silicon-oxide anode material has demonstrated exceptional performance metrics, including:
- 20% increased range for electric vehicles
- Over 1,000 cycles to 80% rated capacity under typical EV conditions
- 90% capacity retention after three months at high temperatures
- Reduced volume expansion during charging cycles
- Cost parity with synthetic graphite at scale
These improvements translate to practical benefits, such as extending EV range by up to 28% and providing eight additional hours of use in portable devices.
Recent Projects
In late 2024, NanoGraf secured a $60 million grant from the U.S. Department of Energy to construct a battery plant in Flint, Michigan. This facility, representing a $175 million total investment, will produce 2,500 tons of silicon anode material annually, supporting up to 1.5 million electric vehicles per year.
The company also expanded its Chicago presence with a new facility at 455 N. Ashland Ave., creating 60 new jobs. Additionally, NanoGraf achieved UL1642 and IEC62133 certifications for its 3.8Ah 18650 cell, enabling mass production starting in 2024.
