StoreDot’s silicon-based nanoparticles serve as the foundational innovation enabling their Extreme Fast Charging (XFC) technology. By replacing conventional graphite anodes with silicon-dominant counterparts, these nanoparticles address critical limitations in traditional lithium-ion batteries.
Key roles of silicon nanoparticles
- Enhanced charging speed: The nanoparticles’ high lithium-ion absorption rate facilitates rapid charging without compromising structural integrity, enabling XFC.
- Volumetric stability: A conductive organic/inorganic matrix surrounds the nanoparticles, accommodating silicon’s natural expansion during charging cycles while maintaining mechanical stability.
- Safety and longevity: Custom electrolyte additives work synergistically with the silicon anode to prevent lithium dendrite formation and extend cycle life (1,200+ cycles to 80% capacity).
The technology achieves 300Wh/kg energy density while maintaining XFC capability ā a combination previously unattainable with graphite-based designs. Recent advancements in prismatic cell integration demonstrate how this silicon-dominant approach adapts to different battery form factors without sacrificing performance.
