Q. HOW MUCH DOES SILICON BATTERY TECHNOLOGY COST COMPARED TO OTHER BATTERIES? Because silicon increases energy density, you can achieve better performance with fewer cells or less weight, which improves pack-level economics. As production scales, the cost per mile driven or per kilowatt-hour delivered over the life of the battery becomes increasingly competitive.
Q. DO SILICON BATTERIES REQUIRE RARE EARTH MINERALS?

» No. Silicon is one of the most abundant elements in the Earth’ s crust.

This abundance supports long-term supply security and resilience.
By reducing dependence on graphite – most of which is exported from China – we’ re reducing dependence on a single source of material and diversifying regional supply chains.
WHAT IS THEIR LIFESPAN?

» Historically, silicon anodes struggled with cycle life due to material expansion during charging. We solved for that by housing silicon in a porous, nano-carbon scaffold that allows for expansion while maintaining stability.
