Nanotech Value Proposition for LFP Cells
- Increase reversible capacity of LFP. Our graphene can be utilized to increase the capacity of LFP by 5-20%.
- Our true mono layer graphene is made in-house and can be produced at scale.
- Graphene can increase the cycling life of the battery. Commercially available LFP particles are normally coated with an amorphous carbon layer. The van der Waals forces between graphene sheets and carbon-coated LFP particles drive the formation of even graphene coating. This feature can provide good protection for LFP particles against the volume expansion or agglomeration while providing improved cycling life.
- Enhance the safety rating of the cells by utilizing patented High Flashpoint/Non-Flammable Electrolytes.
- Increase the power density of the cells by manipulating the electronic and ionic conductivity of the electrodes and electrolytes. Graphene enables an “expressway” to facilitate electron transfer across the particles.
- Improve low temperature performance of the cells.

Designing Next Generation LFP – Safety
Inherently LFP batteries are safer when abused, however the electrolyte is flammable, and the cells will still burn during a thermal runaway event.
Nanotech Energy non-flammable electrolyte eliminates the issue with the liquid electrolyte burning, making the system far safer than it would be with standard electrolytes.
Typical LFP cells contain ~1g of electrolyte per 1.0-1.3Wh of capacity (A 500kWh battery system would have ~500kg, nearly 200 gallons, of electrolyte).
Designing Next Generation LFP – Long Life
Extending the cycle and calendar life of the cells allows for the cost per cycle for batteries and systems to be reduced due to the longer in service lifetime.
Nanotech Energy has technology that can extend the life of LFP while keeping the safety described in the previous section.
Cells at room temperature. After Cycling with Nanotech’s patented Organolyte for 2 years, Nanotech Cell is projecting over 4000 cycles, (cycling 100% DoD, to 80% capacity) where traditional electrolyte projects to ~2000 cycles
Designing Next Generation LFP in Many Formats
- Nanotech Energy materials allow for high-rate capability compared to other LFP battery cells.
- Providing higher power allows for packs, batteries and systems to use fewer cells and provide expanded performance using the same number of cells.
- Brings improved value and reduced cost at the system level due to higher power availability.
- Nanotech Energy Power Cells also have high energy density, nearly energy cell capacity, further improving the performance window for the cells.
Voltage vs. Capacity at Various Rates
Enabling Supply Chain Circularity
Partnership between BASF and Nanotech Energy will enable production of lithium-ion batteries in North America with locally recycled content and low CO2 footprint.
- BASF to produce cathode active materials from recycled metals in Battle Creek, Michigan, USA, for use in Nanotech Energy’s lithium-ion battery cells.
- BASF will be the first company in North America to provide cathode active materials produced with recycled metals on a commercial scale starting in 2024.
- Nanotech will be able to offer cells produced with metals recycled to its customers in North America, ensuring a fully regional supply chain.
