Today on Volts: in lithium-ion batteries, the cathode has been evolving for 30 years, but the anode has remained stubbornly graphite. Now silicon anodes, which promise 5X the energy density & charging speeds, are finally reaching commercial viability. I talk with a silicon-anode pioneer.

Coreshell just launched their first commercial scale 60Ah cells. What's new in that?
Silicon anodes instead of traditional Graphite and domestically sourced metallurgical silicon instead of synthetic silicon.

Silicon can hold 10X the lithium ions that graphite can, but it swells & shrinks when it does so, which has been hell on durability in the past. The unlock here is to create a kind of carbon scaffolding to embed the silicon atoms in, which gives them room to swell & shrink in peace.

Didn’t know graphite was >95% of the anode.
Also didn’t know, ‘While graphite is limited to a theoretical capacity of 372 mAh/g, pure silicon can reach roughly 4,000 mAh/g’ - but silicon breaks, or is expensive to stabilize.
Batteries are important.

Some updates on silicon anode batteries here, which offer greater density and charge speed, avoid graphite (which China dominates the market for), and can be dropped in on existing lithium ion lines. Sionic wants to ship to customers for validation in 2025.

Silicon anodes are coming to market! Huge improvement in energy density (400 Wh/kg!) and charge rates (10 min rapid charging) for Li-ion batteries, and an alternative to graphite, which is almost all sourced from China now. This is one area where US could regain leadership in battery tech.

This reduces dependence on China for Graphite, increases specific energy capacity 10x and decreases material costs by 50%.
No numbers disclosed on that yet but Graphite has 372 mAh/g so their silicon anode will have 3720 mAh/g.

🤞🤞 this works at scale! Sourcing graphite for anodes is one of the biggest challenges if the USA wants to build a resilient supply chain independent of Chinese firms. Silicon anodes are a good alternative w/potential for higher energy density, and several US startups lead the way in this space. 🔌💡🔌🚗

oh, and one more benefit! essentially all graphite today comes from China. but silicon is made from quartz, which is literally just sand. Group14 is based out of Washington state. this is homegrown clean energy tech.
