Anteotech's 70% silicon anode tech leads the silicon race by far but no one knows ? what does Aerotech's marketing guru do for a living ?

One promising approach to developing a stable, high-capacity anode is to leverage the stability of graphite and combine it with the high capacity of metallic silicon or SiOx-based materials to create a composite anode. In this method, metallic silicon or silicon oxide is embedded in a carbon matrix to buffer the volume changes of silicon. Additionally, composite carbon networks enhance electrical conductivity while providing adhesion and increased chemical stability. Other approaches, such as silicon nanowires, carbon coatings on silicon particles, or 3D structures, contribute to the development of highly silicon-enriched anodes. In silicon-based compositions, volume expansion/contraction, mechanical stress, and electrode pulverization during lithiation and delithiation cycles are major concerns when designing a cell with high cycle life (>1,000 cycles), and these issues are heavily influenced by the silicon content. Regarding production costs, the production of silicon composites is higher than that of graphite, metallic silicon, and most SiOx.
