Good to have a VTT report confirming the charging speeds, but the actual differentiator would be the energy density I guess, given that BYD has already proven <10min charging with an LFP battery in an actual car. (https://volta.foundation/battery-report-2025/ pg. 161)

>BYD has already proven <10min

BYD needs to be heavily liquid cooled/thermally managed to achieve that. The Donut battery only had metal heat sink on two or even one side - and its performance was even higher at high temperatures. LFP doesn't behave like that, I think?

Agree, didn't notice that at first in the results, it would potentially allow for less thermal management and even more density at pack level. Curious to see if VTT will also publish a report on the cycles.
