Industry challenge

Silicon oxide achieved market adoption a decade ago, but pain points limit its benefits and addition.

  • Irreversible 1st-cycle loss

  • High-cost production processes

  • High swelling limits anode incorporation

  • No U.S. sources

NanoGraf solution

NanoGraf has developed a proprietary metal-doped SiOx composition and low-cost coating, providing a solution to first-generation challenges.

  • High 1st-cycle efficiency

  • Low-cost production and raw materials 

  • Suppressed swelling enables high blends

  • 100% U.S. owned

OUR COMPETITIVE ADVANTAGE

Solving first-generation commercial SiOx pain points

  • Proprietary surface and core-particular compositions provide a solution to traditional SEI and high irreversible capacity loss challenges

  • Our products have been designed with scalability in mind. Conventional processes and compositions replace costly vapor deposition techniques

  • NanoGraf silicon anodes have lower volumetric changes during charge and discharge, resulting in a more stable electroactive material. Our technology minimizes the deleterious effects of particulate fracture and unwanted calendar life degradation

Empowered by US advanced manufacturing, we are paving the way towards a robust and secure US supply chain.

DROP-IN SOLUTION

Drop-In Manufacturing NanoGraf silicon anodes drop into existing production equipment and processes

Material Compatibility Our product is also compatible with conventional cathode and electrolyte chemistries

HISTORICAL PERFORMANCE OF 18650 CELLS
(1992-2024)

Funded and designed to meet military directives, NanoGraf 3.8Ah 18650 demonstrates a superior energy & power value proposition over 3.5 Ah 18650 cells

Enables +800 Wh/L 18650

NanoGraf aims to become the premier producer of domestic silicon anodes, driving differentiation from the battlefield to US highways.
