Yes, gothitjulie, I know about current battery technology. I was asking about the proposed use of silicon anode cells.
From the article detailing the tests on the silicon anode cells:
“The cells tested by INL have completed 1,000 dynamic stress test (DST) cycles following the USABC three-hour charge protocol, and over 900 DST fast charge cycles using a 4C rate or 15-minute charging protocol under 100% depth of discharge (DOD). The high-rate capable cells can be charged to 80% of their capacity in 10 minutes and to 90% of their capacity in 15 minutes. Zenlabs says its silicon anode cells enable a vehicle with a 300-mile range, and a potential battery life of up to 300,000 miles.”
