Episode notes
Big Bet On Silicon Anodes
- Group14 raised $463M to expand silicon anode manufacturing amid sustained battery demand.
- Investors back silicon anodes as a path to higher energy density and cheaper EVs.
Silicon's Capacity Vs. Stability Tradeoff
- Silicon can store up to 10x more electrons than graphite but swells and crumbles with cycles.
- Startups engineer scaffolds and blends with graphite to preserve stability while boosting capacity.
Scaffold Design Enables Performance Gains
- Group14's scaffold holds silicon in internal voids to accommodate expansion without structural failure.
- The company claims up to 50% energy density gain and sub-10-minute fast charging potential.
