Episode notes
Nanosilicon Enables Extreme Fast Charging
- StoreDot replaces graphite with nanosilicon anodes to enable extreme fast charging.
- Nanosilicon increases surface area and lowers resistance, letting ions move faster with less heat.
High Power And Low Resistance Must Align
- High-power chargers (350+kW) are required to deliver extreme fast charging rates.
- Higher current raises heat exponentially, so lower resistance in the cell is crucial to control temperature.
"100 Miles In 5 Minutes" Exists Now
- Storedot shipped sample batteries achieving "100 miles in 5 minutes" to about 15 OEMs.
- The company produced thousands of these batteries and is iterating further generations.
