NanoGraf, currently the largest silicon oxide anode material producer in the US, announced the release of Onyx — an EV-ready silicon anode material that delivers dramatically improved lithium-ion battery performance at cost parity with synthetic graphite anodes.
Manufactured in NanoGraf’s Chicago facility, with expanded production planned for the company’s recently announced Michigan plant, Onyx is a significant step forward for EV battery anodes.
Onyx’s unique benefits to EV manufacturers include:
- Enhanced materials with no effect on cost: has cost parity at scale with synthetic graphite on a dollar-per-kilowatt-hour basis
- Greater energy density: boasts a 30% improvement in cell energy density compared to synthetic graphite anodes
- Improved capacity: increases EV range by 30% and add significant hours of runtime to portable devices
- Reduced swelling: Onyx’s metal-doped silicon oxide core reduces swelling by 75% compared to traditional silicon, extending overall battery life
- Reliable domestic supply chain: made at NanoGraf Chicago production facility, supporting a more reliable and resilient domestic battery supply chain
Designed to deliver peak performance at a lower price point than other available silicon anode options, Onyx is drop-in ready, and is also suitable for applications, including military, drones, electronics, and more.
In addition to its performance benefits, NanoGraf is one of the few large-scale silicon anode producers that does not use silane gas, a costly and volatile ingredient that has made silicon anodes more expensive and at more risk of supply chain interruptions.
