SiMaxx

Using 100%* Silicon Nanowires, SiMaxx allows volume expansion without binders, graphite, or any inactive materials. The spacing between nanowires and silicon porosity accommodates silicon volume expansion, allowing ions and electrons to travel along the most conductive paths. This results in high-energy capability and fast charge rates.

With the highest commercially available energy density, SiMaxx is ideally suited to power innovations in defense technology, high-performance electric vehicles, and aviation—across unmanned drones, HAPS, eVTOL, and electric planes.

* Actual percentage of silicon is 99.5-99.9% which is within the range of acceptable purity levels for materials that are considered 100%.
