I haven’t found any information about a partnership myself either, but the thought has certainly crossed my mind.
Apparently, a battery can function completely without carbon nanotubes, but with the specs promised by Donut Lab, it is very unlikely without some kind of CNT or similar nanostructure. Without them, charging speed, safety, battery life, etc. would be hard to achieve.
Let’s see.. Without Siilasmaa’s presence, I wouldn’t believe in Donut at all based on this information. There must be some truth to Donut’s claims. Wouldn’t Siilasmaa have surely distanced himself from Donut’s claims quickly if they weren’t true?
