Ecellix Inc., Issaquah, WA, US
There is a race to add silicon to Li-ion negative electrodes due to the tenfold improvement in theoretical capacity over the industry standard of graphite. Technology startups are pushing majority silicon active materials, yet none have made a significant impact. While all offer >3x capacity of graphite, material manufacturing cost is high due to complicated, multi-step synthesis procedures. This also means scaling to support tonne-level production required for Li-ion battery supply is painfully slow and capital intensive. Ecellix delivers a majority silicon active material without these production challenges. While maintaining the >3x capacity, Instead of individual silicon synthesis and carbon coating steps, Ecellix combines everything into a simple one step process. This reduces the manufacturing costs by 50% vs. other silicon startups and has the advantage of being highly scalable, bringing kg to tonne level production to market rapidly, at up to a 75% reduction in production time. Ecellix retains the promises of high performing silicon Li-ion electrodes without the typical manufacturing complexity and price.
